Question

transcribe the dna sequence: tta gga cta
aat gga cta
aat cct cua
aau ccu gau
aau cgu gat

Explanation:

Step1: Recall transcription base pairing rules

In transcription, DNA thymine (T) pairs with RNA adenine (A), DNA adenine (A) pairs with RNA uracil (U), DNA cytosine (C) pairs with RNA guanine (G), and DNA guanine (G) pairs with RNA cytosine (C).

Step2: Transcribe each DNA codon

• DNA codon TTA: T→A, T→A, A→U → AAU
• DNA codon GGA: G→C, G→C, A→U → CCU
• DNA codon CTA: C→G, T→A, A→U → GAU

Combine the transcribed codons: AAU CCU GAU

Step3: Match to options

Compare the transcribed sequence to the given multiple-choice options.

Answer:

AAU CCU GAU
