Question 89 – Reproduction, DNA and protein synthesis - Questions

A synthetic double-stranded DNA gene contains 600 base pairs. Chemical analysis shows that cytosine (C) accounts for 24% of the total nitrogenous bases in this fragment.

During protein synthesis, only one DNA strand is transcribed to produce a pre-mRNA molecule. This pre-mRNA then undergoes splicing, which removes introns that constitute 35% of the primary transcript.

Which of the following correctly identifies the total number of hydrogen bonds in the double-stranded DNA fragment and the maximum number of amino acids in the polypeptide chain translated from the mature mRNA (excluding the stop codon)?

$1512$ hydrogen bonds and $130$ amino acids

$1488$ hydrogen bonds and $259$ amino acids

$1488$ hydrogen bonds and $129$ amino acids

$1344$ hydrogen bonds and $199$ amino acids
