Question 9 1 pts Why are inherited forms of cancer autosomal dominant but not fully penetrant? Even if the mutation is inherited, a loss-of-funciton mutation ipmscting one allele is not expressed The inherited allele is dominant at the cellular level, but might not be expressed depending on genetic background Most inherited mutations are recessive at the cellular level Sporadic, but not inherited forms of cancer forms of cancer are caused by somatic mutation Question 10 1 pts Select true statements...

Question 5: Signal Transduction A. Cancer cells often have acquired mutations that disrupt their ability to undergo programmed cell death. Name three (3) mutations (loss of function or gain of function) in the RTK-PI3 kinase-AKT pathway that would lead to the survival pathway being “always on”. And of course, for each, explain your reasoning. B. There is a phosphatase called PTEN that dephosphorylates phosphorylated inositol phospholipid (PIP3). Would a loss of function in PTEN cause cells to undergo programmed cell...
