Answer:

100 A

100 T

75   C

75   G

Explanation:

there will be an equal amount of thymine and adenine since they bind together so, 200/2 = 100 each

now there is 150 nucleotides left

guanine binds to cytosine so they also have an equal amount, so 150/2=75
  • Given, the number of nucleotides in the section of DNA = 350
  • Nucleotides in DNA are of four types - Adenine (A), Guanine (G), Thymine (T), Cytosine (C).
  • Adenine pairs with Thymine while Guanine pairs with Cytosine.
  • Given, there are 200 nucleotides made by Adenine and Thymine.
  • We know, Adenine pairs with Thymine so they will have equal number of nucleotides.
  • So, the number of Adenine = the number of Thymine = 200 ÷ 2 = 100
  • Number of nucleotides made by Guanine and Cytosine = 350 - 200 = 150
  • We know, Guanine pairs with Cytosine so they will have equal number of nucleotides.
  • Therefore, number of Guanine = number of Cytosine = 150 ÷ 2 = 75

Answer:

As = 100

Ts = 100

Gs = 75

Cs = 75

Hope you could get an idea from here.
