The Gap 2(G2) stage of Interphase
Explanation:
In a eukaryotic cell, the cell cycle refers to both -cell growth and cell division - leading to the production of identical daughter cells. The cell cycle is basically divided into interphase (I) and mitosis (M).
The interphase, during which the cell grows and replicates its DNA takes place by the following stages – Gap 1 (G1), Synthesis (S), Gap 2(G2).
The cells grow and increase in size during the G1 period.
The G2 phase or the second gap phase the cell utilizes energy and produces necessary proteins for undergoing chromosome manipulation and other organelles and prepares the cell for mitotic cell division.
DNA replication mainly takes place in the Synthesis or the S stage of interphase with each of the chromosomes (46) is replicated.
Due to this DNA replication in the S stage, its content is doubled (4-N DNA content) when it enters the G2 stage and all the DNA is found within a single nucleus.
Answer:
E
Explanation:
They need energy to do all these necessary feats.
Answer:
Bacteriophages that induce bacterial cell lysis are called virulent phages.
Explanation:
Bacteriophages correspond to viruses with an affinity for prokaryotic cells to be used as hosts for replication. They act both by invading the bacterial cell and by introducing their genetic material into it.
Some bacteriophages are capable of lysing or destroying the host bacterial cell after replication of their genetic material, receiving the name of virulent phages.
Answer:
cell wall
Explanation:
the cell wall helps fighting any bacteria that tries to infect the cell itself.
The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.
The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.
