11.In the context of signal transduction, which molecules act as "second messengers"? (A) САМР (суclic AMP) (B) Calcium ions (Ca2+) (C) Insulin (D) IP3 (Inositol trisphosphate) (E) DNA polymerase

8. Which are the characteristics of genetic analysis? (A) Some of alleles can exhibit both recessive and dominant properties. (B) Dominant alleles are often the consequence of a mutation that causes some kind of gain of function. (C)Dominant mutations in certain genes are associated with a loss of function. (D)Dominant negative produces a phenotype similar to that obtained from a loss-of function mutation. (E)Recessive and dominant mutant alleles generally have opposite effects on gene function.
