Because at any time, you can find cells that are undergoing mitosis.
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:
This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.
Explanation:
Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.
