This DNA molecule is replicating - write a complimentary strand to this template TAC GGG CAG CAT AAA ATC​
Firdavs [7]

Answer: The complimentary strand will read ATG CCC GTC GTA TTT TAG

Explanation:

The complimentary strand to the replicating DNA molecule is known as messenger RNA (mRNA).

The mRNA directs specific bases to pair the existing base on the replicating DNA strand:

- Adenine (A) pairs only with Thymine (T)

- Guanine (G) pairs only with Cytosine (C)

So, to obtain the complimentary strand of TAC GGG CAG CAT AAA ATC​, substitute each letter with its base pair.

Thus, the complimentary strand will read ATG CCC GTC GTA TTT TAG
