Question

Go through the following facts –

I. ‘AAG’ always code for lysine. It cannot code for any other amino acid.

II. Serine amino acid can be coded by UCU / UCC UCA or UCG.

III. UUU from phenyl alanine in bacteria as well as human beings.

IV. UUU GGG CCC AAA AAC codes for five amino acids.

Now point out nature of genetic code after reading above.

• A. I – Specificity/Non-ambiguityof code;II – Universality of code; III – Degeneracy of code; IV – Triplet & nonoverlapping code
• B. I – Specificity/ Non-ambiguity of code; II – Degeneracy of code; III – Universality of code; IV – Triplet & nonoverlapping code
• C. I – Specificity / Non-ambiguity of code; II – Degeneracy of code; III – Universality of code; IV – Triplet & overlapping code
• D. I – Specificity / Non-ambiguity of code; II – Universality of code; III – Degeneracy of code; IV – Triplet & overlapping code
