Question

Give the complementary strand for: ATCGGTA

Answer 1

Knowing that the second polynucleotide strand of DNA complements and or base pairs with that of the original strand, based on the base pairing rules as shown:

A - T
G - C

Then the complementary strand would be :

TAGCCAT

Answer 2

Answer: The complementary strand for given sequence of DNA is TAGCCAT.

There are two complementary strands that are present in a double helical structure of DNA.

According to Watson and Crick base pairing-

Adenine (A) forms base pair with Thymine (T) and Guanine (G) forms base pair with Cytosine (C) in a double stranded DNA molecule.

As per the question, sequence of one strand is given that is ATCGGTA.

Therefore, the sequence of complementary strand is TAGCCAT.
