Ans.

Memory cells of immune system are present in G0 phase, in which these cells are not activated or responding for a pathogen.

The cell-cycle is defined as the series of events that lead to DNA duplication and division of a cell to form daughter cells. The cell cycle is divided into interphase and M phase.

The interphase includes gap 1 (G 1) phase, S or synthesis phase, and gap 2 (G 2) phase, while M phase includes karyokinesis and cytokinesis.

The cells after M phase either goes for next cell division or G1 phase or for G 0 (gap 0) phase. The G0 phase is resting phase, in which cells show a quiescent state.

As memory cells are present in resting phase, till the next exposure of same antigen, these cells are in G0 phase of cell cycle.

Which is the main reason cells are replaced in the body?. The cells are too large.. The cells are inactive.. The cells are damag
anygoal [31]

The right answer is The cells are damaged.

Take the example of skin cells.  

The skin consists of two tissues:

* the outermost, the epidermis, resting on a vascularized connective tissue,

* the dermis.

In the epidermis, which includes several layers of cells, the outer layer is formed of dead cells that are desquamating and are constantly being replaced from proliferating basal cell cells. So, in normal conditions, the epidermis is in constant renewal.

On the other hand, when accidentally, the upper parts of the epidermis are damaged, for example, a slight abrasion or of a burn, the destroyed portion is regenerated (replaced) thanks to an accelerated proliferation of basal epidermal cells .

WILL MARK BRAINLIEST. <br> How can PCR and gel electrophoresis be used to identify people?
Talja [164]

Answer: answer

Explanation: Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized by gel electrophoresis, sent for sequencing, or digested with restriction enzymes and cloned into a plasmid.
