Question

A DNA sequence is shown: TAGCATGAG. What is produced when the sequence is transcribed?

1) a section of DNA with the base sequence ATCGTACTC
2) a section of mRNA with the base sequence AUCGUACUC
3) a section of mRNA with the base sequence AUCCUCGUA

Answer 1

I’m pretty sure it’s 1

Answer 2

Answer:

2) a section of mRNA with base sequence AUCGUACUC

Explanation:

To transcribe the sequence means to find the mRNA sequence. First, get the DNA sequence that will pair with the given sequence.  Next, change the symbol of thymine to uracil.

The first option contains the DNA sequence that will pair with the given sequence. If thymine is changed to uracil, the answer is AUCGUACUC.
