Answer:
The correct answer would be A) CGATTA
During DNA replication, the daughter strand is synthesized on the basis of complementary base pairs i.e. purines will always base-pair with pyrimidine.
The two strands are joined together with the help of hydrogen bonding between the nitrogen bases of the nucleotides.
The adenine will always base pair with thymine with the help of 2 hydrogen bonds and guanine will always base pair with cytosine with the help of 3 hydrogen bonds.
