Answer:

The salient feature of genetic code are as follows:

(i) The codon is a triplet. 61 codons code for 20 amino acids and 3 codons do not code for any amino acids, hence they function as stop codons.

(ii) One codon codes for only one amino acid, hence, it is unambiguous and specific.

(iii) The code is degenerate because some amino acids are coded by more than one codon.

(iv)The codon is read in mRNA in a contiguous fashion. There are no punctuations.

(v)The code is nearly universal.

The salient features of genetic code are as follows:

i The codon is triplet. 61 codons code for amino acids and 3 codons do not code for any amino acids hence they function as stop codons.

ii One codon codes for only one amino acid hence it is unambiguous and specific.

iii Some amino acids are coded by more than one codon hence the code is degenerate.

iv The codon is read in mRNA in a contiguous fashion. There are no punctuations.

v The code is nearly universal: for example from bacteria to human UUU would code for Phenylalanine phe. Some exceptions to this rule have been found in mitochondrial codons and in some protozoans.

vi AUG has dual functions. It codes for Methionine met and it also act as initiator codon.

Thank you sister for marking my answer as brainlist.

can I call you sister?❤

and what is your name tell me please ❤
