In which phase of the cell cycle does DNA replication take place, and which statement BEST explains why DNA replication is impor
tant? A G0: DNA replication is important because it ensures survival of the organism and survival of the species. B G2 phase: DNA replication is important because it ensures survival of the organism and survival of the species. C G1 phase: DNA replication is important because it ensures that each daughter cell receives precisely the same number of chromosomes and genetic information contained within the parent cell. D S phase: DNA replication is important because it ensures that each daughter cell receives precisely the same number of chromosomes and genetic information contained within the parent cell.
The correct answer is - option D. S phase: DNA replication is important because it ensures that each daughter cell receives precisely the same number of chromosomes and genetic information contained within the parent cell.
Explanation:
DNA replication takes place during the cell division in order to produce or divide into two identical or exact copies of the DNA molecule or chromosome that would be transferred to the daughter cells equally.
DNA replication occurs in the S phase of the cell cycle or cell division. It is also known as the synthesis phase which comes after G1 phase and followed by G2 phase in the cell cycle.
I will take the position of helper that work for the betterment of environment by reducing such activities that can increase the carbondioxide concentration in the atmosphere. The main reason for this position is the destruction and damages that occurs in the environment and to organisms that are present all around the world. This global warming leads to the extinction of these species so in order to protect them I choose this position.
A vaccine is used to provide active acquired immunity to the host by supplying them with a biological preparation which is often made up of attenuated organism, its associated immunogenic particle, protein, DNA, etc.
Today there are vaccines available for a wide variety of diseases however there is no preventive vaccine for listeriosis.
Listeriosis is a disease caused by <em>Listeria monocytogenes</em> and it is a very serious disease often caused due to the consumption of contaminated food.
There is unavailability of a commercially available vaccine against listeriosis although a lot of research is underway to prepare a vaccine to reduce the mortality rate.
