Consider how alternative splicing could allow many different protiens to be encoded by the same gene?

Suppose that a consensus sequence in the regulatory promotor of a eukaryotic gene that encodes an enzyme – let's call it finalexamase – was deleted. Which of the following effects would result from this deletion? (yes or no) 1. Finalexamase would have a different amino acid sequence. (yes or no)? 2. The mRNA for finalexamase would be abnormally short. (yes or no)? 3. Finalexamase would be missing some amino acids. (yes or no)? 4. The mRNA for finalexamase would be transcribed but not translated. (yes or no)? 5. The quantity of mRNA for finalexamase that is transcribed would be affected. (yes or no)?

Let's say there is an eukaryotic gene that has five exons and 4 introns. If the GU sequence at the 5' splice site of the third intron is deleted, describe how this is going to affect the expression of this gene. draw the mature mRNA too.

Research has demonstrated that the composition of a gene’s promoter can affect alternative splicing of its RNA transcript. For example, promoters that are activated by certain transcriptional activator proteins cause one form of alternative splicing; when these activators are not present, a different form of splicing takes place. Propose some possible mechanisms by which the promoter could affect alternative splicing.
