Hemophilia A is a genetic disorder of recessive X chromosome mutation of the Factor VIII gene that causes a blood clotting protein Factor VIII missing or deficient. If a person with XY chromosomes is affected by Hemophilia A and a person with XX chromosomes is an unaffected person, what is the probability that their male offspring might be hemophilic and what is the probability that their female offspring might be carriers of the mutated gene?

A DNA coding sequence of ATGCGTGGA(sequence for the rest of the gene)AATTAA encodes a protein chain of 200 amino acids of MET-ARG-GLY-(196 more amino acids)-ASN after splicing. A mutation occurs in which the third G is changed to a T. Using the genetic code below, determine which type of mutation this is and briefly explain how translation will be affected for this protein chain.

In a wild-type carnivorous plant, protein X is encoded by a haplosufficient gene “X”. The X protein normally homodimerizes. The X-X dimer enzymatically catalyzes a biochemical reaction that is critical for the digestion of insects that it traps. XD represents a dominant negative allele, a mutation, of gene X. What would be the predicted phenotype of a plant with the genotype X+/XD ? Which one of these pieces of information allows you to reach that conclusion? a. The plant would...

Draw a box-and-arrow (SMRF) model representing your understanding of HOW information in the lysozyme gene (LYZ) is used in a human cell to produce the lysozyme protein. model should include the following structures: amino acids, chromosome, DNA, gene, mRNA, nucleotides, protein. Make sure the wording of your model is specific to the example of lysozyme.

Explain what classifies a mutation as “temperature‑sensitive” by comparing phenotype(s) with a wildtype allele. How is this type of phenotype explained by protein behaviour? Would the following types of mutations most likely have: severe effects, mild effects, or no effect on protein function? Briefly explain your answers. Note that there may be more than one correct answer, but you need only to give one sensible answer and explain your reasoning. [6 marks] A nonsense mutation occurring in sequences encoding amino...
