Why is there a need to produce Okazaki fragments on the lagging strand, but not on the leading strand of DNA?
A. The two parental strands of DNA are antiparallel and DNA polymerase makes DNA in the 5? to 3? direction only. B. It is substantially more efficient to make several shorter strands rather than one longer strand of DNA. C. There is not enough cellular DNA ligase for bonding Okazaki fragments together if they were produced from both parental strands. D. By having one leading strand and one lagging strand the cell can limit the amount of DNA polymerase used for chromosomal replication. E. The leading strand opens first, and so Okazaki fragments are not needed. The lagging strand unwinds second resulting in the need to produce Okazaki fragments.

You discover a gene that results in a complete lack of hair in rats, and you name the gene "chromedome." A cross of homozygous normal and homozygous bald rats results in all bald rats. You conclude that the baldness allele is dominant, but when you repeat the cross with different rats none of the offspring are bald. Extremely puzzled you study your records and discover that in the first cross the bald rat was female, while in the second cross the bald rat was male. What do you conclude from this information?
A. chromedome is imprinted in males. B. chromedome is dominant in females and recessive in males. C. chromedome is dominant in males and recessive in females. D. chromedome is an X-linked gene. E. chromedome is imprinted in females.
