Question

When a protein is synthesized, cis- or trans-splicing of that protein occurs ___________?

1) following translation
2) between transcription and translation
3) during transcription
4) prior to transcription

Answer 1

Cis- or trans-splicing occurs between transcription and translation in the nucleus, where pre-mRNA is processed to become mature mRNA that is ready for translation into protein.

Step-by-step explanation:

When a protein is synthesized, the cis- or trans-splicing of that protein occurs between transcription and translation, which is the processing phase where the pre-mRNA is modified to become mature mRNA. This splicing event takes place in the nucleus after the RNA transcription process. Once the pre-mRNA has been processed to remove introns and splice exons together, it becomes mature mRNA that is then transported to the cytoplasm for translation into a protein. The sequence of events is critical for ensuring that the cellular machinery correctly translates the genetic code into a functional protein.
