Answer:
The correct answer will be option-B
Explanation:
The process of transcription transcribes the sequence of the bases of genes present on DNA to mRNA which acts as a messenger molecule for the protein synthesis.
The process of transcription is mediated by the presence of enzymes which includes the main transcription enzyme called RNA polymerase. RNA polymerase attaches nucleotides to RNA strand.
The transcription process initiates in three stages: initiation, elongation and termination.
The initiation process begins when RNA polymerase binds to the promoter nucleotide sequence which is present at the start site or the upstream on DNA towards 5' end.
Thus, Option-B is the correct answer.
<span>Anaerobic respiration takes place in the fluid portion of the cytoplasm of cells, away from the mitochondria or any other organelles. It begins with glycolysis, which breaks apart glucose and generates energy and a compound known as pyruvate, and also includes fermentation, which breaks down the pyruvate for more energy. </span>
Hey there!
The sides of DNA have rails, or the sides of them that keep them together- and what's amazing is you can't even see it.
They're made of sugar (deoxyribose) and phosphate molecules. They alternate, so sugar, phosphate and so on.
Hope this helps!
