Answer to Question #164949 in Genetics for Sam

Question

Discuss how the genetic code allows proteins to be synthesised with minimal errors taking place, including:

• triplet codes

• codon

• anticodon

• degenerate code

• non-overlapping  

Answer 1

During protein synthesis, tri-nucleotides or triplet codes or codons are paired by anticodons on the tRNA that on the opposite end bears a corresponding amino acid that is added to a growing polypeptide chain, or otherwise synthesized to form a backbone for the growth of a polypeptide chain, this mechanism important in reducing the error rates that occur during this process. To be able to decode all the 64 codons the body has developed a mechanism called wobbling or the four way wobbling that allows only 32 tRNA molecules to pair and translate all the 64 possible codons.
