Question

When DNA Is duplicated from mRNA which DNA, mRNA uses a __ nucleotide instead of T.

If the mRNA sequence is GUACUGUAC, what is the DNA Sequence? __
Please and thank you

Answer 1

1. When DNA is duplicated from mRNA which DNA, mRNA uses a U nucleotide instead of T.

2. If the mRNA sequence is GUACUGUAC, the DNA Sequence is CATGACATG.

Step-by-step explanation:

1. The only thing that changes from a DNA sequence to an RNA sequence is that the thymine (T) in DNA is changed to Uracil (U) in RNA.

2. There should be no Uracil (U) in a DNA sequence–– only ATCG. Just matching with the given pairings.

G can transcribed to C.

C can be transcribed to G.

A can be transcribed to T.

U can be transcribed to A.
