Step by step
Solved in 2 steps
- X-inactivation can result in two clones of a cell that differ in the genes they express. Can you think of other reasons why two genetically identical individuals might look different from each other?What is the effect of the NDM gene?Describe the molecular process of X-chromosome inactivation.This description should include the three phases of inactivationand the role of the Xic. Explain what happens to the X chromosomes during embryogenesis, in adult somatic cells, and duringoogenesis.
- Explain how X-inactivation in female mammals results inpatchy coat color in calico cats.During X inactivation, all but one gene get silenced on one X chromosome. Why does one gene escape the inactivation? A) That is the gene responsible for inactivating the others B) Two copies of that gene are needed in females, so both are active C) X inactivation is rarely complete, so occasionally one or two genes get activated by mistake D) That is the gene that encodes the methyltransferase needed to methylate the genome.What are the two ways in each X ray cause damage and what DNA repair pathways are important for correcting this type of damage?
