Question

given that the gene for insulin is provided below, what will the corresponding mrna sequence be? hint! remember that a will pair with u. insulin gene sequence (dna): dna → acg-tag-tag-acg. what will be the mrna sequence? dna ——> rna t pairs with a a pairs with u g pairs with c c pairs with g

Explanation:

Step1: Transcribe first DNA segment (ACG)

In DNA to RNA transcription, A→U, C→G, G→C, T→A. For ACG: A→U, C→G, G→C. So ACG becomes UGC.

Step2: Transcribe second DNA segment (TAG)

T→A, A→U, G→C. So TAG becomes AUC.

Step3: Transcribe third DNA segment (TAG)

Same as second segment, TAG becomes AUC.

Step4: Transcribe fourth DNA segment (ACG)

Same as first segment, ACG becomes UGC.

Step5: Combine the transcribed segments

Combine UGC, AUC, AUC, UGC. So the mRNA sequence is UGC - AUC - AUC - UGC.

Answer:

UGC - AUC - AUC - UGC
