In DNA, nucleotides with adenine account for 18%. Determine the percentage of nucleotides with cytosine that make up the molecule.

According to Chargaff’s Rule, the number of nucleotides in double-stranded DNA is calculated by the formula: (A + T) + (G + C) = 100%, while, according to the principle of complementarity, A = T; G = C
If it is known that A = 18%, then C = (100% – (18% + 18%)) / 2 = 32%

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
