Transcription is the transfer of genetic information from DNA to RNA, and it happens in the nucleus. We can automatically rule out B. B is incorrect because it doesn't make sense; how can a process stop before it even begins?
A. I believe this is incorrect because mRNA is involved when the genetic information needs to leave the nucleus. mRNA would take it to a ribosome outside of a nucleus. Since transcription happens in the nucleus, mRNA is irrelevant before it starts.
C. This doesn't really make sense. mRNA carries information from the DNA, but not vice versa (in these early stages).
D. This would make the most sense, since RNA polymerase needs to attach to the promoter on the strand before transcription can begin.
Habitat
Explanation:
Habitat is a given area where organisms interact with non-living things.
The dwelling place of living organisms is their habitat and it is the produced as a result of interaction between the organism and non-living components.
- The habitat of an organism defines its niche in such an environment.
- This is related to the roles which organisms perform in the ecosystem.
- Ecosystem is the interaction between organisms and the non-living components with their environment.

10 chromosomes. After telophase and cytokinesis, the new daughter cells will each have 10 chromosomes, which is identical to the parental cell. Human cells have 23 pairs of chromosomes.
Answer:
<h2>
Codon
</h2>
Explanation:
The sequence of DNA is transcribed into mRNA, containing the sequence for protein synthesis, protein is synthesized according to the codons in mRNA. This sequence of nucleotide on DNA/ RNA is divided into a series of three nucleotide units, and one unit of three nucleotide is known as codons.
There are overall 64 codons, 61 codons out of 64 codons, codes for overall 20 amino acids, and the remaining three are stop codons.
These there codon do not code for any amino acid.
And these 61 codons, they code for total 20 amino acids. So one amino acid can be coded by one or more than one codons.
