What happens during mRNA processing?

No changes to mRNA structure.

Only exons are removed.

Introns are removed, exons are joined together.

Introns are kept, exons are removed.

1

What molecule is added to the 5' end of mRNA?

Introns are added back.

A 5' cap is added for stability.

RNA splicing occurs here.

A poly-A tail is added.

1

Where is the poly-A tail added in mRNA processing?

During DNA replication process.

Inside the ribosome after translation.

At the 3' end of the mRNA molecule.

At the 5' end of the mRNA.
