Question

In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine?

Answer 1

73%

Step-by-step explanation:

Given: 27%

To find: Percentage of nitrogenous bases are cytosine

Solve:
`(27)/(100)` ×
`(100)/(1)`

Firstly, divide 100% by thymine and cytosine

`(100)/(2)` = 50

Now, If it is 50 / 50, but thymine has 27 then subtract 27 from 100

100 - 27 = 73

So, the percentage of nitrogenous bases are cytosine 73%
