Question

Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA, can you use it to predict the amounts of all four nucleotide bases when you only know the amount of one type of base? Approximately 21% of the human genome is comprised of nucleotides containing C. Given this information, calculate the percentage of the human genome that is comprised of nucleotides containing G, T, and A. (a) _____% of the human genome is comprised of G.

(b) _____% of the human genome is comprised of T.

(c) _____% of the human genome is comprised of A.

Answer 1

21% of the human genome is comprised of G

29% of the human genome is comprised of T

29% of the human genome is comprised of A

Step-by-step explanation:

According to Chargaff's rule,

The double stranded DNA,contain purine and pyrimidine.Adenine makes pair with thymine and cytosine make bond with guanine.

In the above problem,The amount of Cytosine is 21% thus the amount of guanine will be 21%

Total amount of cytosine and guanine=21+21=42

then the total amount adenine and thymine is =100-42=58

The amount of adenine is=
`(58)/(2)`=29%

The amount of thymine is=29%
