a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
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.

Mutation rate of Gram negative bacteria is much greater than that of Gram positive bacteria.
Explanation:
The gram positive types of bacteria responsible for causing diseases in humans. It is called as Gram positive bacteria. Both the bacteria are different in structural and physical properties. It is defined as the group of bacteria’s which positive result in gram stain test.
Gram negative bacteria are the group of bacteria’s which gives negative result to the gram stain test. This classification is done according to the cell wall. The cause of common disease by Gram positive bacteria is our anthrax, diphtheria, etc.

The only cell that has a rectangular shape is a plant cell duo to the cell wall.
The large spaces inside the cell are the vacuoles.
The green dots are chloroplasts.
