Khorana synthesized two RNAs (a) with repeat sequence of AB and (b) with repeat sequence of ABC, the polypeptides coded by (a) & (b) are respectively.

Which of the following mRNA is translated completely.
(A) 5' AUG UGA UUA AAG AAA 3'
(B) 5' AUG AUA UUG CCC UGA 3'
(C) 5' AGU UAG AGA CUC UAA 3'
(D) 5' AUG UAC AGU AAC UAG 3'

A strand of DNA has following base sequence 3' AAAAGTGACTAGTGA 5'. On transcription, it produces an mRNA which of the following anticodon of tRNA recognizes the third codon of this mRNA?

Degenerated DNA after heating can be studied by comparing

If in an mRNA base sequence is 5' AUG CUA UAC CUC CUU UAU CUG UGA 3'. How many amino acid residues will make up the polypeptide corresponding to this mRNA?

Consider the following sequence on mRNA, AUGGCAGUGCCA. Assuming that genetic code is overlap then how many number of codon may be present on this genetic code?

Suppose evolution on earth has occurred in such a way that there are 96 amino acids instead of 20. DNA has 12 different types of bases and DNA synthesis occur in the same way as today. The minimum number of bases per DNA codon would be

The total number of nitrogenous bases in human genome is estimated to be about

The process involved in the RNA formation on the DNA template is called as

The first codon discovered by Nirenberg and Matthaei was
