Answer:
Off-pump coronary artery bypass
Explanation:
In this heart bypass surgery a vein or artery from another part of the body is taken and used as a graft to replace the blocked coronary artery. The benefit of this type of surgery is that there is negligible chances of rejection of the graft because the graft has been taken from the same body. A surgical cut is made inside leg, between the ankle and groin and one end of the graft is attached to coronary artery whereas the other end to the opening of aorta.
Radial artery of wrist is also common graft in heart bypass surgery.
Answer:
B.) Replication fork
Explanation:
The replication fork is the point at which two strands of DNA separate via DNA helicase.
The origin of replication is the site on a singular DNA strand where replication begins. Here, complementary nucleotides begin bonding to the single-stranded DNA via DNA polymerase.
The replication bubble is created when DNA helicase separates a DNA strand. The DNA helicase does not separate the entire strand, but rather opens only certain sections at one time. This creates a "bubble" in the DNA strand where replication will take place.
Okazaki fragments are formed on the lagging strand of the single-stranded DNA. Because DNA is only created from the 5' to 3' direction, RNA primase must reposition itself after adding a primer (made of nucleotides). DNA polymerase then fills in these fragments with more complementary nucleotides in small sections.
