Question

Replication creates a complementary strand of DNA. Given the following parental strand of DNA, what would be the nucleotide sequence of the daughter strand? AACTGGCATCGACTAGGG

Answer 1

Nucleotide sequence

Explanation:

Here in this question no direction is given for the sequence but DNA replication always occurs in 5'-3' direction so we will rewrite the sequence as:

5'AACTGGCATCGACTAGGG3'

But parental strand acts as a template for the synthesis of daughter strand hence it will be read in 3'-5'direction

3'GGGATCAGCTACGGTCAA5'

The daughter strand will be complementary to the parental strand and always synthesized in 5'-3' direction

5'CCCTAGTCGATGCCAGTT3'

Note:If no direction is given for the nucleotide sequence then we take 5'-3' as the direction because DNA is synthesized in this direction
