"Meiosis II is not completed until after the egg cell makes contact with the sperm cell." This is false because, for both genders, meiosis splits into haploid cells. The end of Meiosis II would be when the four haploid cells are separated.

Indicate whether each of the following occurs mainly in G1 phase (G), S phase (S), or G2 phase (H) of the cell cycle. Your answe
Ronch [10]

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
