Question

a eukaryotic gene has the following structure: a-b-c-d-e-f. b and e are introns. which representation best describes how this region of mrna will appear after it is transcribed and processed by a spliceosome?

Answer 1

The mRNA region after transcription and splicing, with introns removed by the spliceosome, will appear as a-c-d-f, containing only the exons.

Step-by-step explanation:

The eukaryotic gene structure mentioned in the student's question is composed of segments a-b-c-d-e-f, where b and e represent introns. After transcription and processing by a spliceosome, introns are removed from the pre-mRNA. The remaining exons, which are the coding sequences, are then reconnected. Therefore, the mRNA region after transcription and splicing would appear as a-c-d-f. This processed mRNA is then ready for translation into a functional protein.
