Question

• Given a single strand of DNA, be able to determine the complementary

DNA strand.
Example-TATTTCCCGGTCGTAA
What is the complementary strand to this section of DNA?

Answer 1

The complementary DNA strand to the sequence 5'-TATTTCCCGGTCGTAA-3' is 3'-ATAAAGGGCCAGCATT-5', following base pairing rules where A pairs with T, and G pairs with C.

Step-by-step explanation:

To determine the complementary DNA strand for a given sequence, you need to understand that DNA strands are antiparallel, and the nucleotides pair up according to specific base pairing rules where adenine (A) pairs with thymine (T) and guanine (G) pairs with cytosine (C). For the DNA sequence 5'-TATTTCCCGGTCGTAA-3', the complementary strand would be the opposite sequence where each nucleotide is replaced with its complement. o determine the complementary DNA strand for a given sequence, you need to understand that DNA strands are antiparallel Therefore, the complementary strand would be 3'-ATAAAGGGCCAGCATT-5'.

Answer 2

the complementary should be: ATAAAGGGCCAGCATT
