Question

Complete the mRNA sequence that will be formed from the DNA sequence TAC CGC CCC on mRNA and Amino Acid

Answer 1

I’ll give both common interpretations (depending on whether the given DNA is the template strand or the coding strand).

1) If TAC CGC CCC is the DNA template strand (3' → 5'):
- mRNA (5' → 3'): AUG GCG GGG
- Amino acids (from those codons): Met - Ala - Gly (M - A - G)

2) If TAC CGC CCC is the DNA coding (sense) strand (5' → 3'):
- mRNA (5' → 3'): UAC CGC CCC
- Amino acids: Tyr - Arg - Pro (Y - R - P)

Note: transcription base-pairing rules: A (DNA) → U (RNA), T → A, C ↔ G. Translation uses codons in mRNA (three bases) to specify amino acids.
