The nitrogenous bases were examined in a specific sequence of DNA that codes for a
gene that creates a protein. 70% of the DNA was adenine. What percent of the DNA
would you expect the scientist to find for thymine in that same genetic sequence?
А
0%
B
25%
с
30%
D
70%

Respuesta :

D 70%. Adenine pairs with thymine so if there was 70% of adenine it would match and vice versa. Same goes with guanine and cytosine

In the given DNA sequence, the percentage of the DNA would you expect the scientist to find for thymine in that same genetic sequence - D. 70%

Chargaff's rules

The DNA from any cell of all organisms should have a 1:1 ratio of purine which is cytosine, thymine and pyrimidine bases which guanine and adenine.

As we know Adenine always binds with thymine in DNA then there would be always equal in each sample or sequence. Thus, the the percentage of the DNA would you expect the scientist to find for thymine in that same genetic sequence would be 70%.
