23.Which statements about leading and lagging strand synthesis is/are CORRECТ? (A) The leading strand is synthesized continuously. (B) The lagging strand requires RNA primers. (C) Okazaki fragments are longer in eukaryotes than in prokaryotes. (E) (D) DNA polymerase 8 extends lagging-strand DNA in eukaryotes. The lagging strand is produced by 3'→5' synthesis.

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.
