The answer should be "a" but it needs to read the promoter region of a gene is bound to the enzymeRNA polymerase, positioning the enzyme on the correct DNA strand.
In the process of transcription, an enzyme called RNA polymerase recognizes and binds to a DNA nucleotide sequence just before the beginning of the gene. This recognition site, called a promoter, positions RNA polymerase properly on the correct DNA strand and points it in the right direction.
The DNA strands then separate over a short distance and the polymerase moves into the gene and as it moves, it creates a new chain by linking together individual ribonucleotides existing free in the cell, This new chain or strand is called messenger RNA.
I want to say the answer is B because during the process of photosynthesis, the catabolic process of the light phase is used to drive the anabolic process into the dark which means the catabolic is the light stage and the anabolic is the dark stage
