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.
The genes involved in pattern formation and organization of body parts are called homeobox genes, which are a large family of similar genes.
The h<span>omeobox genes direct the formation of many body structures during early development of the embryo. </span>
Answer will be b for question
By examining the F1 complex of ATP synthase which is from Bovine heart mitochondria. Then we should ask what prevents F1 complex from rotating with Fo c-ring complex?. It is bound to the central stalk. F1 rotates with Fo c-ring complex and nothing prevents it. The mitochondrial membrane is where Fo c-ring is bounded. Stationary "a" subunit of Fo is where the stator which is connected to it bounds.
In conclusion, we will say that the answer is, it is bounded by the stator, which is corrected to the stationary "a" subunit of Fo.
The ring-shaped C subunits form the rotor of the F1FO complex. FOF1 is bound to the central stalk, Therefore, it prevents it from rotation which is during the translocation of protons
