Answer

Salient Features of Genetic Code

Unambiguous: Each codon codes for only one amino acid, which means there is no ambiguity in the genetic code.

Degenerate: The genetic code is degenerate because multiple codons can code for the same amino acid. This is due to the presence of redundancy in the code, where some amino acids are coded for by more than one codon. For example, the amino acid leucine is coded for by six different codons.

Universal: The genetic code is universal, which means that it is the same in all living organisms. This allows for the transfer of genetic information between different organisms.

Non-overlapping: The genetic code is non-overlapping, which means that each nucleotide in the DNA sequence is read only once and is part of only one codon.

Start and stop codons: The genetic code has specific codons that serve as start and stop signals for protein synthesis. The start codon (AUG) codes for the amino acid methionine, while the stop codons (UAA, UAG, and UGA) signal the end of the protein chain.

Conserved: The genetic code is highly conserved, which means that it has remained relatively unchanged throughout evolution.

Non-ambiguous: The genetic code is non-ambiguous, which means that each codon can only code for one specific amino acid.

Commaless: The genetic code is commaless, which means that there are no gaps or commas between codons.

Redundant: The genetic code is redundant, which means that some amino acids are coded for by more than one codon.

The genetic code is the set of instructions that determines how DNA is translated into proteins. It is composed of a series of three-nucleotide codons that specify the order in which amino acids are assembled to form proteins. The salient features of the genetic code include its unambiguous nature, its degeneracy, its universality, its non-overlapping nature, its start and stop codons, its conservation, its non-ambiguity, its commaless nature, and its redundancy. These features allow for the accurate and efficient translation of genetic information into functional proteins.
