The flow of urine from the bladder is controlled by the

C

Explanation:

A)

DNA directs the synthesis of RNA.

B)

DNA splits into two strands of RNA.

C)

A strand of DNA is used as a template for the formation of RNA.

D)

Two strands of RNA are formed by copying each of the strands of DNA.

The correct answer would be that a strand of DNA is used as a template for the formation of RNA.

Transcription is a process during which RNA is synthesized using DNA as a template. The coding strand of the DNA is utilized as a template for the formation of messenger RNA. During this process, the double helix structure of the DNA is unwound by an enzyme and the coding strand is bound by a short DNA strand at the beginning of a gene while another enzyme adds RNA nucleotide bases to elongate the short strand.

The correct option is C.
