Question

Analysis of the genome of a newly discovered bacterial strain reveals that it is composed of a double-stranded DNA molecule containing 16% thymine. Based on this information, what would you predict the percentage of cytosine to be?

Answer 1

Answer:

Cytosine = 34%

Explanation:

Given percentage of thymine in a double stranded DNA of newly discovered bacterial strain = 16%

Since thymine pairs with adenine, percentage of adenine in this DNA = 16%

Total percentage of thymine and adenine = 16% + 16% = 32%

Out of total 100%, the percentage of guanine + cytosine = 100-32% = 68%

So, percentage of cytosine = 68% / 2= 34%
