Answer:
The correct option is A) RNA polymerase.
Explanation:
RNA polymerase is an essential enzyme complex to carry out transcription, these enzymes are responsible for transcribing DNA into RNA. Using a DNA template, RNA polymerase builds a new RNA molecule through base pairing. This process is the first step of gene expression, and is called transcription. RNA polymerase binds to DNA in a very particular region or sequence, called a promoter.
In order to prepare for division the cell has to Replicate DNA
Precipitation differences are the factor that does not contribute to "water stress" on the Earth.
<u>Explanation:</u>
- Less ocean water sources, population differences, Scarcity of economic water resources are the factor which leads to water stress on the Earth.
- Precipitation differences do not cause much difference in water stress. So it will not contribute to the water stress.
- An increase in population will cause major water stress because availability drinking water is less in the earth. Population increase can cause a major problem.
Explanation:
Body cells make up the body of any multicellular organism. A body cell contains a complete number of chromosomes and is called a diploid cell while a gamete contains only half the number of chromosomes of its parent cell, and it is called a haploid cell.
