Question

practice transcribing a gene and then process the mrna transcript
mrna processing
mrna processing
process the mrna using the bases and protective sequences below:
5
aaaaaaaaaaaa cc ggg uuu 5 cap

← 2 / 3 →

Explanation:

Step1: Identify exons and introns

Exons are coding regions (green) and introns are non - coding (red).

Step2: Remove introns

The pre - mRNA sequence has introns UCCG and AUUCGA. After removal, we are left with the exons: UACGGGACGGUA.

Step3: Add 5' cap

Add the 5' cap sequence given (not specified in full here but conceptually).

Step4: Add poly - A tail

Add the poly - A tail sequence AAAAAAAAAA.

Answer:

The processed mRNA would have the exons joined together with a 5' cap and a poly - A tail added. The exon sequence is UACGGGACGGUA. With the addition of the 5' cap and poly - A tail (AAAAAAAAAA), the final mRNA would be in a processed form ready for translation. However, without full details of the 5' cap sequence, we can only state the exon part clearly as UACGGGACGGUA.
