As shown in the following diagram, a pre-mRNA contains seven exons, which are numbered in black, and six introns, which are numbered in green. A splicing repressor binds at the 3′ splice site at the end of intron 4, which is just before exon 5. What exons will be included in the mature mRNA?
The asterisk (*) in the diagram below indicates a single base mutation in the 5' splice site of the second intron of a eukaryotic gene. Due to this mutation, the second intron is now not ‘spliced out’ during the splicing process. What are the most likely consequences of this mutation with respect to the size of the pre-mRNA and the size of the mature mRNA? a. The pre-mRNA will be longer and the mature mRNA will be longer. b. The pre-mRNA will be longer and the size of the mature mRNA will not be affected c. The size of the pre-mRNA will not be affected and the mature mRNA will be longer d. The size of the pre-mRNA will not be affected and the size of the mature mRNA will not be affected

A diagram of a gene is shown below. Normally, exons 1, 2, and 3 are present in the mature mRNA. (shown in attatched image) A mutation occurred at the 5’ splice site of exon 1 as shown by the star such that the spliceosome cannot bind to this location during mRNA processing of the pre-mRNA into the mature mRNA. Which of the following is/are a possible result of this mutation? (select all that apply) a)The pre-mRNA transcribed from this gene sequence will be longer than normal. b)The protein translated from this mRNA will be a different length than the normal protein. c)The mature mRNA will be longer. d)The mature mRNA will be shorter.
"The gene for Receptor Z contains an unknown number of untranslated first exons that are spliced to a common exon 2" - what does it mean if a "first exon" is "spliced to a common exon 2"? Does it mean that Exon 1 is attached to Exon 2, but Exon 1 is not part of the translated protein - similar to the below schematic? mRNA Option 1: [Exon 1a][Exon 2][Exon 3].... mRNA Option 2:[Exon1b][Exon2][Exon 3] mRNA Option 3: [Exon1c][Exon2][Exon 3]
