Question

A DNA segment contains 100 Adenine and 100 cytosine, how many nucleotides are present in the segment?

Answer 1

Answer:

hey mate ur answer will be 400

Answer 2

400 nucleotides are present in the segment.

• The number of nucleotides in the segment can be calculated by using the Chargaff rule.
• Chargaff rule states the ratio of purine and pyrimidine is always 1:1. So, an equal amount of adenine will bind with guanine and an equal amount of cytosine will bind thymine.
• So, 100 adenine will bind with 100 guanine and 100 cytosine will bind with 100 thymine.
• Adding up all the numbers, we get 400 nucleotides.
