An original dna strand has the following base sequence: cctaggtaa what base sequence would be produced through dna replication

The correct answer is-

GGATCCATT.

DNA replication is a process of formation of two molecules of DNA using single molecule of DNA ( which is double stranded).

In this process, two strands are first separated and act like template strand, using which enzyme DNA polymerase adds dNTPs ( deoxyribonucleoside triphosphate) complementary to the template strand in the direction 5' to 3'.

According to Watson and Crick base pairing, Adenine ( A) in the template DNA pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C) during the process of replication of DNA.

The sequence of  original DNA strand  is- CCTAGGTAA

Thus, complementary strand would be-   GGATCCATT
