Which statement best describes the role of dna in relation to rna and proteins?
a. dna is made from rna, which is created from proteins.
b. proteins are made from rna, which is created from dna.
c. rna is made from dna, which is created from proteins.
d. proteins are made from dna, which is created from rna.

B. proteins are made from rna, which is created from dna

dna is the basic unit which contains all the genetic information of the cell. dna is transcribed into rna by rna polymerase. this type of rna is called messenger rna, which goes into the cytoplasm to be translated into proteins. these proteins then control various activities of the cell, including dna replication, cell duplication, etc.
