A gene has six exons, labeled 1 through 6.
A gene has six exons, labeled 1 through 6. The mRNA transcript of this gene can be spliced in several ways, but to produce a functional protein, each mRNA must have exactly three exons, two of which must be 2 and 4. Hint to answer the following questions:
- How many different mRNAs can be produced from this gene, and what are they?
- If all genes in this organism were capable of producing this same number of mRNAs, how may genes would the organism need to produce 100,000 different polypeptides?
