The following is the only intron sequence of a gene that will be excised during the maturation of the mRNA. But it is not spliced in some tissues, where alternative splicing pattern is seen. Will the amino acid of its protein product following this sequence change? Explain with an example. ATGATAGCCAGACTCGCA

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
"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]
