Textbook Question
Chapter 6, Problem 5CRCAQ
Old Norse stories tell of a famous Viking named Egil, an actual person who lived
around A.D. 900. His skull was greatly enlarged and misshapen, and the cranial
bones were hardened and thickened (6 cm, or several inches, thick). After he died,
his skull was dug up, and it withstood the blow of an ax without damage. In life, he
had headaches from the pressure exerted by enlarged vertebrae on his spinal cord.
So much blood was diverted to his bones to support their extensive remodeling that
his �ngers and toes always felt cold, and his heart was damaged through overexertion.
What bone disorder did Egil probably have?

For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C.

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
