Hi all, I am struggling to see the difference between tRNA and Anti-Codons, can anyone help elucidate? Any help apreciated.

In summary, tRNA and anti-codons are two important components involved in protein synthesis. The anti-codon is a small part of the tRNA that is complementary to the mRNA codon and helps to bring the correct amino acid to the ribosome. The tRNA is a larger structure made up of nucleotides and is important for shaping the molecule and aiding in interactions with other molecules in the cell. The amino acids are not made from the tRNA, but are either obtained through diet or synthesized in other parts of the cell and then attached to the tRNA.

The anti-codon refers to a specific part of the tRNA (3 nt of the ~80-90 nt that compose the tRNA).

I'm a Gr12 Learner I don't know what "nt" is :P. So in layman terms the anti-codon is the base triplet complementary to the mRNA codon and tRNA is Anti-Codon + Amino Acid?

Oops, my bad. nt stands for nucleotide. A tRNA is a fairly large structure made up of 80-90 nucleotides (see picture below).
The anticodon is only a small part of the tRNA, and only 3 of the ~ 80-90 bases in the tRNA form the anticodon. The rest of the tRNA is important for defining the overall shape of the tRNA molecule to help it interact with the ribosome and other molecules within the cell (such as the enzymes that attach the amino acid to the tRNA).

Good answer. Much obliged. How does the amino acid get made from the tRNA? does the trna become the amino acid?

No, the amino acids are not synthesized from the tRNA. The amino acids are either obtained through diet or synthesized in other parts of the cell then later attached to the end of the tRNA (see the diagram in my previous post to see where the amino acid gets attached).NotASmurf said:

ohkay thank you. Teacher made it seem like they did, did well in the test thought, Thanks for your help :)
FAQ: Difference between tRNA and Anti-Codon
What is tRNA?
tRNA, or transfer RNA, is a type of RNA molecule that plays a crucial role in protein synthesis. It carries amino acids to the ribosome, where they are assembled into proteins according to the instructions encoded in the mRNA.
What is an anti-codon?
An anti-codon is a sequence of three nucleotides on tRNA that is complementary to a specific codon on mRNA. It helps to ensure that the correct amino acid is added to the growing protein chain during translation.
How is tRNA different from anti-codon?
tRNA and anti-codon are two different components of the protein synthesis process. tRNA is a type of RNA molecule that carries amino acids to the ribosome, while anti-codon is a specific sequence on tRNA that is complementary to a codon on mRNA. In simple terms, tRNA is the carrier, while anti-codon is the identifier.
Can tRNA have more than one anti-codon?
Yes, tRNA can have more than one anti-codon. This is because there are 20 different amino acids used in protein synthesis, but only 64 possible codons (4 nucleotides in groups of 3 can make 64 combinations). Therefore, some amino acids have more than one codon, and tRNA with different anti-codons can carry the same amino acid.
What happens if there is a mismatch between tRNA and anti-codon?
If there is a mismatch between tRNA and anti-codon, the wrong amino acid will be added to the growing protein chain. This can result in a change in the genetic code and potentially lead to the production of a non-functional or even harmful protein. However, cells have mechanisms to detect and correct these errors, helping to maintain the accuracy of protein synthesis.
