Learning Goal - Protein Synthesis - Post-transcriptional modification in eukaryotic cells
3 important questions on Learning Goal - Protein Synthesis - Post-transcriptional modification in eukaryotic cells
Outline location and timing of post-transcriptional modification of RNA.
In the nucleus, before being sent out in the cytoplasm for translation.
Compare intron and exon sequences of genes.
Introns are non-coding sequences that are multi-functional, helping for mRNA processing, due to how their removal aids the different order in which the exons (coding sequences) are spliced together, contributing to the greater complexity of the mRNA, due to how they are enabled to code for multiple proteins.
Outline and describe the process of alternative RNA splicing.
Alternative RNA splicing involves the process of removing introns from the pre-mRNA and splicing together the remaining exons in different alternative orders, not straying away from the pre-determined base sequence. This could involve removal of certain exons, and splicing together of remaining exons.
The question on the page originate from the summary of the following study material:
