3.Which of the following is/are involved in the processing of eukaryotic pre-mRNA? (A)5' capping (7-methylguanosine) (B)Polyadenylation at the 3' end (C) Removal of exons by the spliceosome (D) Removal of introns by the spliceosome (E) Binding of the Shine-Dalgarno sequence

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.
