Assume 102 nucleotide pairs of DNA to be responsible for transcription of particular mRNA molecule. What is the length of that mRNA in (1) angstrom? (2) in micrometers?

In Figure 9-12, is the terminal amino acid emerging fromthe ribosome encoded by the 5′or 3′end of the mRNA?

A eukaryotic mRNA has 703 total nucleotides. 50 of these are the 5'UTR and 50 of these are the 3'UTR. How many amino acids are in the protein encoded by this mRNA?Question 26 options: A) 199 B) 200 C) 201 D) 300 E) 700

First start with a pre-MRNA with four exons and three introns and diagram the splicing reactions leading to the four exons being spliced together (a) Second, show the following two alternative splicing diagrams that would produce (b) intron 2 retention, otherwise similar to part (a) (c) mutually exclusive exon (exon 1- either exon 2 or exon 3 -- exon 4) (d) exon 2 skipping, otherwise, similar to part (a). For part (d), explain how an SR protein could influence whether exon 2 is skipped. What would happen if SR binding to the exon 2 ESE was weak? Which MRNA isoform would be more abundant?
