The answer is B: CGT
According to the base pairing rules, in DNA, adenine
pairs with thymine (A-T), and cytosine pairs with guanine (C-G).
The complementary triplet for GCA is CGT. So, for the DNA segment AGT CAC GCA, the complementary strand will be TCA GTG CGT:
Known strand: <span>AGT CAC GCA</span>
<span>Corresponding strand: TCA GTG CGT</span>
In the early 1960's, the United States tried to overthrow the communist leader, Fidel Castro. They were unsuccessful in the attempts.
