The central dogma states that information flows from

a.

RNA to DNA to polysaccharides.

b.

DNA to RNA to proteins.

c.

RNA to DNA to proteins.

d.

DNA to polysaccharides to RNA.

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.
