Answer:

Correct choice should be:

"SGSG"

Explanation:

The cell cycle consists of G1, S, G2 and M phase. The former three phases include the interphase and M phase is the dividing phase of cell . G1 prepares cell for DNA synthesis. S phase is the phase where DNA replication takes place. G2 phase prepares cell for cell division or M phase.

G1 phase preceeds replication or S phase and G1 phase licences DNA replication.

During other phases of cell cycle, ORC complex masks origin of replication. ORC phosphorylation takes place at S phase, which removes this omplex and unmasks origin of repication site so that replication machinery can bind to it.

DNA helicase activation: S phase

DNA helicase deposition on DNA at the replication origins: G phase (actually G1)

ORC phosphorylation: S phase

Licensing of replication origins : G phase (actually G1)

Hence correct choice should be:

SGSG

Persons with __________ blood have neither antigen a nor antigen b on their red blood cells but have antibody anti-a and antibod
Flura [38]

Persons with O blood have neither antigen a nor antigen b on their red blood cells but have antibody anti-a and antibody anti-b in their plasma.

ABO blood grouping was discovered by Austrian scientist Landsteiner. It consist of four blood groups- A, B, AB, & O.

Red blood cells have certain extension of the proteins that are called antigen. Two types of antigens are there antigen a & b. The RBCs which have a particular antigen will not have the antibody against the same.

Blood Group A has antigen A and antibody B. Blood group B has antigen B and antibody A. Blood group AB has both antigen and no antibodies while blood group O has no antigen and antibody A & B.
