Question

if part of the dna gene being transcribed is tgcaat, what will the mrna code be for that part?
o ucgttu
o ugcaau
o tgcaat
o acguua

Explanation:

During transcription, DNA is transcribed to mRNA. The base - pairing rules are: A (adenine) in DNA pairs with U (uracil) in mRNA, T (thymine) in DNA pairs with A (adenine) in mRNA, G (guanine) in DNA pairs with C (cytosine) in mRNA, and C (cytosine) in DNA pairs with G (guanine) in mRNA.

Given the DNA sequence TGCAAT:

• T pairs with A
• G pairs with C
• C pairs with G
• A pairs with U
• A pairs with U
• T pairs with A

So the mRNA sequence is ACGUUA.

Answer:

ACGUUA
