DNA Replication: The Role of Base Pairing in Creating a Complementary Strand – GATCCA

during DNA replication a DNA strand that has the bases CTAGGT produces a strand with the bases



During DNA replication, the double helix DNA separates into two strands by breaking the hydrogen bonds between the complementary base pairs. Each strand serves as a template for the synthesis of a new complementary strand, and the process of replication proceeds in two directions – from the origin of replication.

In the given case, the template strand has the sequence CTAGGT, this sequence will be matched with complementary bases on the new strand. Adenine (A) will bond with thymine (T), and guanine (G) will bond with cytosine (C). Therefore, the newly synthesized strand will have the complementary sequence of GATCCA:

Template strand: CTAGGT
New strand : GATCCA

The key principle of DNA replication is base pairing, which ensures that each newly synthesized strand is an exact copy of the original template strand. This process is carried out by a complex molecular machinery involving various enzymes which collectively ensure precise and accurate replication of the DNA molecule.
