G G A---T A G---C C G---T T A Find the mRNA strand. *

CCUAUCGGCAAU

Explanation:

This question is describing the process of transcription, which is the process by which a DNA strand is used as template to synthesize a mRNA strand or molecule. This synthesis in transcription, which is carried out by an enzymes called RNA polymerase, is based on the COMPLEMENTARY BASE PAIRING RULE.

Complementary base pairing rule states that Adenine base will always hydrogen pair with Thymine while Guanine will always pair with Cytosine. However, Uracil base (U) replaces Thymine (T) in RNA. Hence, the pairing is as follows: A-U, T-A, G-C etc.

Based on the above, a DNA strand containing the following sequence: G G A---T A G---C C G---T T A will be transcribed into the following sequence of mRNA: CCUAUCGGCAAU.

okay now i don't know this but for the pints nothing else to say bye
