B
Information is encoded in DNA, then copied onto RNA during transcription. Then, ribosomes convert the information carried in RNA into a protein, in the process of translation. Also, A and D could be ruled out because DNA and RNA are solely involved with proteins, but polysacchariades are chains of sugars.
The enzyme will likely be less affective or more affective, however, it depends on what the perfect temps tire is. since this sounds like it is lowering its temp from the “ideal range”, the enzyme will be less effective!
This process of dna copying would be mitosis.
