A eukaryotic gene codes for a digestive enzyme.
(a) Outline the differences between transcription and translation in a eukaryotic cell by constructing a table with the following features:
- cellular location
- template used
- main enzyme(s) or molecular machines involved
- product(s) formed
- any post-synthetic modifications that occur before the product is functional.
(b) A substitution mutation occurs in the coding sequence of this gene. Describe how this mutation could alter the final polypeptide, and state one possible consequence if the mutation changes a codon to a stop codon.
