Answer: The instructions in the DNA is copied into an mRNA (messenger RNA) which then moves out of the nucleus to the ribosome where it is used in protein synthesis.

Explanation: DNA is a genetic material found in the nucleus which contains the instructions needed to encode a protein or an RNA.

The instructions or information encoded in the DNA is first copied into an mRNA in a process known as transcription. This process takes place in the nucleus.

The mRNA synthesized from the DNA then leaves the nucleus and gets to the ribosome where it is used as a template for protein synthesis. The instructions encoded in the mRNA is read in the ribosome and is converted into amino acid sequence of a protein.
