What is the purpose of transcription??
A. To link amino acids together to form strands of protein
B. To produce a nucleic acid sequence from an amino acid sequence.
C. To from RNA molecules from DNA.
D. To copy the nucleotides in DNA.

C. To from RNA molecules from DNA.

Explanation: Transcription is a process in which the genetic information present in a DNA molecule is copied into a complementary RNA molecule. This process occur in the nucleus. There are three classes of RNA that can be synthesized from a DNA molecule: messenger RNA (mRNA), transfer RNA (tRNA) and ribosomal RNA (rRNA). The RNA produced leaves the nucleus and is transported to the site where it is needed. mRNA serves as a template for protein synthesis, rRNA forms part of the ribosome where proteins are synthesized while tRNA helps in fetching and attaching the correct amino acid residue during protein synthesis.
