Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA,
Elza [17]

Answer:

The correct answer will be- 21, 29, 29

Explanation:

In a DNA sequence, the nucleotide base pairs on one strand of DNA are  complementary to the base pair on other strand of DNA.

According to the Chargaff rule, Adenine binds Thymine and Cytosine binds Guanosine which shows that the amount of A will equal T and the amount of G will equal C.

Therefore, when the amount of C is 21%, then the amount of G will be 21%.

To find amount of AT= 100-GC

                              AT= 100-42

                                AT= 58%

So, AT/2= 29% each

Thus, A=T= 29%

          G=C=21%
