A fragment of a DNA molecule has a length of 3400 nm. How many cytidyl nucleotides are included in this fragment if 20 adenyl nucleotides are found in it?
Answer: P = 4980.
Knowing the length of the whole DNA section, you can find out the number of nucleotides contained in it (length 1 NC = 0.34 nm). n NC = 3400 nm / 0.34 nm = 10,000 40 = 9960. According to the principle of complementarity, G = C as well as A = T, which means G = C = 4980.
