A fragment of a DNA molecule consists of 1000 nucleotides, of which 23% are adenyl nucleotides. Determine the amount of guanyl, thymidyl and cytidyl nucleotides.
1000 nucleotides is 100%, let’s determine how many nucleotides are 23% of adenyl ones: 23 ∙ 1000: 100 = 230 nucleotides, A = T = 230, 1000-460 (A + T) = 540 (G + C); G = C = 270 (540: 2)
Answer: G-270, T-230, C-270 nucleotides in a DNA fragment
