Imagine that you are a scientist studying DNA. You measure the number of cytosines and thymines in a small strand of DNA. There are 45 cytosines and 55 thymines. How many guanines are there?How many adenines are there?

Sagot :

Easy, for every Adenine there will be another complementary Thymine on the other strand of the double helix, for every cytosine there will be a guanine, Look at this pic so its easier to understand
The answer is 45 guanines and 55 adenines

In the given DNA, guanines are there 45 and adenines are 55.

Deoxyribose Nucleic Acid (DNA)

It is a polymer of nucleotides known as a genetic unit. A DNA molecule consists of three parts—

  1. A nitrogen base
  2. A five-carbon sugar called deoxyribose, and
  3. A phosphate group.

Nitrogen bases

In DNA there are four nitrogenous bases adenine, thymine, cytosine, and guanine.

Adenine always bonds with thymine and cytosine always bonds with guanine so the number of adenine would be equal to thymine and the number of guanines would be equal to cytosine.
