Answer:
There would be no fertilization.
Explanation:
When the fallopian tube is blocked, even after ovulation (an egg released by the ovary), it will be unable to travel down the fallopian tube towards the uterus. This way, even when the sperm swim up to the tube (where fertilization of the egg usually occur) after copulation, it will be unable to meet the egg and fertilize it. There will never be conception as long as there is blockage on location X.
Answer:
c. YACs
Explanation:
YACs, the Yeast artificial chromosomes are the high capacity vectors designed to carry the eukaryotic genes and carry the insert of 200-2000 kb.
YACs carry origin of replication from yeast, selectable markers and sequences derived from telomeres and centromere to maintain the stability of the insert during cell division.
The insert size for plasmids, bacteriophage, PACs, and cosmids is about 0.1-10 kb, 5-25 kb, 100-300 kb, 35-45 kb respectively.
