How many nucleotides with thymine do DNA molecules contain if the amount of nucleotides with adenine is 30% of the total?
| December 8, 2020 | education
By the principle of complementarity: the amount of Adenine corresponds to the amount of Thymine, the amount of Guanine corresponds to the amount of Cytosine.
Total in the molecule is 100% (A + G + C + T).
Therefore, Timina is -30%.
30 + 30 = 60% – Thimin + Adenine.
100-60 = 40% – Guanine + Cytosine.
40: 2 = 20% – Guanine or Cytosine.
