Mutation Definition and 48 Threads

I came across an article on CNN on a bunch of scientists researching the dangers of very old viruses that have been "paused" within the northern permafrost and their prospects of causing infection due to their release which might happen as the permafrost decreases...

If different eyes appeared let say to less sun or an accidental mutation, has it become subject to selection of individuals like eugenism or due to modern gene technology nowadays ?

https://www.biorxiv.org/content/10.1101/2021.01.08.425835v1.full Can prime editing fix every mutation in every type of cell in the body?. From what I read in the article the editing efficiency of prime editing using adeno-associated virus is 1.82%, so what prevent us from repeating the same...

Given the seeming increased transmissibility of the new SARS-CoV-2 variants being identified, I thought I'd start a general thread to collect and organize information on the various mutations to the SARS-CoV-2 virus. B.1.1.7 variant (aka 20B/501Y.V1, VOC 202012/01; originally identified in the...

When I see the term random mutation in popular writings on evolution (social sciences major here, so please forgive my ignorance), I wonder what it precisely refers to. I understand we can have have gene mutations due to exogenous factors, such as exposure to UV light, or from "errors" in the...

Yup, it's mutated to be more contagious and has a higher viral load in patients, but does NOT change the severity of symptoms. It is a mutation that was noted back in Feb., 2020 of the original version from China, it has spread worldwide. 52 page research article in Cell ...

Homework Statement Question 2[/B] You mutagenize male flies with EMS. Next you mate an EMS-treated male fly to a wild-type female fly. (i) If you find an F1 offspring with a sleep-too-little mutant phenotype, what does that suggest to you about this mutation? (ii) You expect that majority of...

I got this question in an exam. Why do silent mutations always affect the third position of a codon? I have no clue about it.

is Mutation /evolution as a result of quantum jump? and is it possible that the collapse of the quantum state alters the nucleotide sequence of the genome of some creatures. thank you ! <mentor moved the thread from Biology to Quantum Physics>

1.Above sentence means in 1074 mutations(Events) just one of them could make a functional protein and that mutation is beneficial? 2.Is above sentence similar to "Hoyle's calculation of the Odds of Life", thus the criticism against Hoyle's idea can apply to above sentence? Like this:

I was wondering if anyone knew what happens to a protein that gets wrongly assembled due to a mutated RNA? Does it just do a slightly different or very destructive action in the organism, or does the organism catch it and kick it out? Also an extra side question: Speaking of mutations of RNA...

Ygggdrasil submitted a new PF Insights post What Causes Cancer: Bad Luck or Bad Lifestyles? Continue reading the Original PF Insights Post.

Homework Statement UV Rays is said to induce point mutations which get incorporated during the DNA replication process. These mutations are corrected by the excision repair mechanism of the DNA polymerase but sometimes they might be left out. In one of such cases, point insertions were...

I am an evolutionary theoretician, focusing on the dynamics of process that shape the generation of variation in organisms, including properties such as mutational robustness, the evolution of evolvability, and modularity in the genotype-phenotype map. My main mathematical area is development...

In a recent thread I posted there was mention of evolution having a specific sense in biology. I just spent an hour reading some evolution primers and I think I have a better sense of how this works at the molecular level but will need to read a lot more till it all hangs together in my mind...

Homework Statement Homework Equations The Attempt at a Solution From what I can see in the data given there must be at LEAST 3 mutations I found 5: Initial: UCU UAU GGC Final: UAU (1 mutation) UUA (2 mutaions) UUG (2 mutations) or Final: UAU (1 mutation) CUU (2 mutaions) UUG...

When I first encountered the term genetic mutation, I envisioned a gene that had somehow spoiled – like an orange with mole on it. A little research indicated that a gene is a linear string of amino acids that codes for a protein. The term mutant gene was being used to indicate a gene in...

Please tell me it dosent? http://en.wikipedia.org/wiki/Alternative_theories_of_quantum_evolution

I am an electrical engineer. Just curious about evolution. I was watching a documentary about evolution. So evolution happens because of mutation. But what exactly trigger or starts mutation. The DNA or part of DNA which turns ON/OFF other DNA, what exactly is it called. Where can I read...

hey guys, sorry for coming here with these potentially stupid topics, but tbo, this is the closest thing I have to biologists or biology enthusiasts on the subject. My question came from creationist who does not accept evolution...He says that evolution is false because mutations are repaired...

Homework Statement there is a virus that infects a baterium. the viral genome was a 5000base long rna strand and it contained 4 genes for attacking the bacterium and reproducing. this rna strand was placed in a test tube with free nucleotides to allow it to reproduce. thus after many repeated...

If a organism has a dna mutation, would this not imply that some trait is lost. If there is a mutation then somewhere in the dna there is a difference which would cause something to be missing. Is this right? If this is the case then how come complicated speices still have all there original...

Consider the DNA of a human. How many single, individual, molecular mutations are possible?

Hi, i would like to ask why is addition or deletion of one base in mutation is not as severe as addition or deletion of 3 base in mutation? If it were to make enzyme the shape would be gone right?

Homework Statement Is it true that gene and chromosomal mutation are similar in the sense that they both can occur through translocation? Can an increase in genetic material occur in both then? Are chromosomal mutations due more often to mitosis or meiosis? Homework Equations The...

This is a question of semantics(?). Biologists are not known to be gods of well-definedness, but if there actually exists an argument over the following question (even a possibility), then I might get some credit back on some classwork. What is the definition of a dominant mutation (of a...

Homework Statement The effects of a mutation are not always visible. How might a biologist determine whether a mutation has occurred, and if so, what type of mutation it is? Homework Equations The Attempt at a Solution Would it be correct to say that cancer is not always...

I know this is a long post, but bear with me.. this is what I've got through several days of reserach. I've always woundered about the mathematical aspects of evolution. I've heard such facts that the mutation rate is fairly consistant and can be used as a biological "clock" to track events...

To jump from a single celled organism to a multicellular one, we need beneficial addition mutations in DNA sequences. My question is this: has this phenomena ever been observed? By beneficial I mean a mutation in the genotype that serves to cause some phenotype that can be used by an organism...

If you were to select healthy and smart people from our gene pool (in hopes of creating better humans), and let them reproduce in isolation without further intervention, would the generations of offspring down the line still develop the same ailments that the general population develops...

hi :smile: i am new over here,needed a little help from u people. i have an assignment to do in which i have to discuss about any 4 examples linking dna mutation to disease

Using dendrochronology to get DNA mutation rates? A question: Would it be possible to use DNA analysis in combination with tree ring dating get an accurate DNA mutation rate? By extracting DNA from the inner rings of a tree, shouldn't it be possible to compare it to the DNA from outer...

What does the 'random' in random mutation really mean?

There is a general belief that radiation can cause genetic mutation. I have never understood the mechanism by which such mutation could result. An alpha particle (+helium nucleus), beta particle (-electron) or a gamma ray (high energy em radiation with a wavelength smaller than an atomic...

As I've learned it, mutations can be grouped into 3 categories as they relate to evolution: harmful, neutral, or beneficial. Is there any way to figure out the ratios (in relation to each other) of these types of mutations?

Hello all, First I'd like to say that I'm not a great scientists nor a great thinker. All I do is try to derive a common logic. A few days ago, I had a lesson on "how do mutations affect us." And so I copied all the definitions into my notebook. One of them was 'Germ-line mutation" and...

Here is another question (the previous one about meteor impact) concerning extraterrestrial effects upon terrestrial selection: Could the incidence of mutations increase substantially during times of magnetic pole shifts? The unstable Van Allen belts then might allow more radiation to reach...

I have a project to do with viral mutation, but i haven't found any information how the virus changes, just that it does. can anyone tell me exactly how the virus mutates? Thanks :smile:

i...I'd like to know if all of the attacks made by any kinds of virus are the same all the time. My answer although i am still not really sure is NO, IT ISN'T, therefore, ii...the mutation rate of different virus is always different, but where can i find or how to know of how fast it really...

Mutation is one of the important factors to cause evolution, but besides radiation, what cause mutation to happen? Is it happen naturally?

i always hear the same examples; antibiotics resistance of bacteria, ddt , anemia examples…. These are all invalid. Just please tell me one valid example of beneficial mutation if there is. Also backup your example please. By the way i suggest you to check this before you write...

I am interested in finding out more about mutation but so far I haven't found much on the topic... What would be a place to start if you are only familiar with the basics of DNA replication... translation.. transcription... I don't know much on the subject... thanks. News reguarding...

"The researchers' new discovery involves a gene called MYH16, which had apparently gone unrecognized because of a small mutation that had rendered it inactive for producing some jaw muscles for chewing and biting. The scientists found that this myosin gene was still intact today in other...

I am wondering, are there certain statistical probabilities of mutations? Like, which one is more likely a transistion or a transversion (and what do they mean)?

Belgian farmers had been breeding a bull for its muscle size, finally getting a bull who is supermuscular http://www.ultimate-exercise.com/bravenewworld.html This supermuscularity is caused by a mutation is the myostatin gene. Why has this case not been exploited yet? Or am I just not...

What is the main cause behind mutation in evolution?
