Question

If DNA has the sequences of bases TCAAGT, the mRNA formed during transcription would have the sequence of

Answer 1

Answer:

The correct answer is option C. "AGUUCA".

Explanation:

When mRNA is synthesized from a DNA sequence, the RNA polymerase catalyses the addition of nucleotides in the process known as transcription. During the synthesis the RNA polymerase adds the complementary sequence of the DNA template, with the only difference that molecules of uracil are added instead of the molecules of adenosine. Given that adenosine binds to thymine, and cytosine binds to guanosine, the mRNA formed from the DNA sequence "TCAAGT" will be "AGUUCA".

Answer 2

It is C, because DNA has 2 pairs: a t and c g.
When translated into RNA, a pairs with u instead.
