Genetic code Definition and 12 Threads

Summary: Curious to find out genetic code other than DNA <mentor> Moved to Discussion, hypothetical discussion Dear PF Forum, It's been a long time since I log into PF. And I hope everybody is in a good health. Recently I had a discussion debate with my friend about other life in this...

I just did my morning exercise while listening to a short youtube talk on genetics. I do not understand it but what struck me was it seemed to be on the level of an EE discussing OHM's law, Transistor theory, and digital logic terms. Now I know all the rules that make my PC on which I am...

Now i had a question,but before that look at this. Now by the central dogma DNA is transcribed by RNA polymerase onto mRNA and this leads to translation which creates Protiens. But hold on...The polymerase itself is an enzyme ie ;a protein . So to make proteins...you need proteins aldredy...

All life on Earth stores its genetic information in DNA using just four nucleotide letters: A, T, C, and G. Research published this week in the journal Nature describes how scientists engineered a bacterium to incorporate two new letters into their DNA (which they call X and Y, pictured below)...

According to https://www.ncbi.nlm.nih.gov/books/NBK21950/ and some other sources: 'Genetic code is the set of correspondences between nucleotide pair triplets in DNA and amino acids in protein.' What dose correspondences mean in this regard? I don't understand why nucleotide pair triplets and...

Homework Statement Val-tRNA val is the tRNA that carries valine to the ribosome during translation. Which of the following sequences gives an appropriate anticodon for this tRNA? A. CAU B. AUC C. UAC D. GUG Homework Equations There are four different codons for Valine: GUU, GUC, GUA, and...

Thoughts on this? http://journal.frontiersin.org/Journal/10.3389/fgene.2014.00140/full The codon redundancy (“degeneracy”) found in protein-coding regions of mRNA also prescribes Translational Pausing (TP). When coupled with the appropriate interpreters, multiple meanings and functions are...

http://www.bbc.co.uk/news/science-environment-14492948" Just want to discuss this development. IMO, we are not prepared for this kind of revolution, unless we fully understand the implications and effect of engineering the genetic code without exactly knowing the outcome. I know this is...

Interesting, never trust a dogma. Genetic Code Supports Targeted Insertion of Two Amino Acids by One Codon "Call it the genetic version of a double-entendre. Scientific dogma dictates that various three-letter combinations of our genetic sequence each "mean" exactly one thing--each codes...

Hello, Here's a conceptual question: The wobble effect says that 1 tRNA can be used for more than 1 anticodon, as the nucleotide near the 5' position of the anticodon does not need to follow strict base pairing rules. The degeneracy of the genetic code refers to the fact that more than...

I'm having problems with three terms that are used to describe the genetic code: universality redundancy non-overlapping reading frame 1) Universality: For the most part, I understand. I know that the universality of the code allows for the limited exchange of genetic information among...

codons aren't basic units of the genetic code right? my friend told me that it does but i remember in lecture that proff said it doesn't but maybe i misheard
