A scientist discovers a species of bacteria. The relative percentage of adenine base in its DNA is about 23%.
What is the expected percentage for the other three bases?
thymine: 27%; guanine: 27%; cytosine: 23%
thymine: 23%; guanine: 23%; cytosine: 23%
thymine: 23%; guanine: 27%; cytosine: 27%
thymine: 27%; guanine: 23%; cytosine: 23%

Respuesta :

Answer:

B

Explanation:

The expected percentage for the other three bases in the given case, -

thymine: 23%; guanine: 27%; cytosine: 27%

Chargaff's Rule

DNA is made up of those four nucleic acids. Adenine always pairs with Thymine in DNA. Guanine always pairs with Cytosine. Adenine and thymine are complementary in a 1:1 ratio. Similarly, guanine and cytosine are complementary in a 1:1 ratio.

So according to the given information, there is 23% adenine so there is 23% thymine. The remaining 54% is divided between guanine and cytosine equally in a 1:1 ratio. Thus there will be 27% G and 27% C respectively.
