Question

A DNA molecule has the sequence GCATCCGA. What is the mRNA sequence resulting for this DNA code?

Answer 1

The mRNA is the opposite of DNA but make whatever would be thymine uracil so the answer should be CGUAGGCU

Answer 2

Answer: The mRNA sequence is CGUAGGCU

The sequence of DNA molecule is GCATCCGA and when it is transcribed, it forms mRNA ( messenger RNA). The mRNA sequence is complementary to the DNA template. The corresponding nucleotides in mRNA are added in the following manner-

For G in the DNA, C ( cytosine) is added in mRNA and vice versa. Similarly, for A ( adenine) , U ( Uracil) is added in mRNA and for T( thymine), A ( adenine) is added in mRNA.

Thus, for the given DNA sequence, CGUAGGCU is the right mRNA sequence.
