Question

During gene expression, when DNA is being transcribed into RNA, the non-coding sections are removed. The remaining coding segments are connected. This process is called(1 point)

senescence.


transcription.

splicing.


translation.

Answer 1

The answer is splicing.

Answer 2

During gene expression, when DNA is being transcribed into RNA, the non-coding sections are removed in a process called RNA splicing.

• RNA splicing is a process by which non-coding gene regions called introns are removed from the precursor messenger RNA (pre-mRNA), whereas coding gene regions called exons are spliced together.

• The spliceosome is a macromolecular complex that catalyzes the removal of introns from the pre-mRNA.

• This process (RNA splicing) helps to create many functional mature mRNAs from a single primary transcript.

In conclusion, during gene expression, when DNA is being transcribed into RNA, the non-coding sections are removed in a process called RNA splicing.
