how can I transcibe this into mRNA?

DNA- T A C G A C T A A C G T C A G T A G

To transcribe DNA into mRNA, you need to follow the rules of base pairing. In DNA, the base pairs are adenine (A) with thymine (T) and cytosine (C) with guanine (G). However, in mRNA, thymine (T) is replaced with uracil (U). So, to transcribe the given DNA sequence into mRNA, you would replace each T with U.

Given DNA sequence: T A C G A C T A A C G T C A G T A G

Transcribed mRNA sequence: A U G C U G A U U G C A G U C U A C

Therefore, the transcribed mRNA sequence is A U G C U G A U U G C A G U C U A C.
