Translation can be described as

• the process of making a protein in the nucleus

• the transfer of the instructions from the nucleus to the cytoplasm

• the process in which the genetic code in mRNA is read to make a protein

• the transfer of genetic instructions in DNA to mRNA

A section of nucleic acid is shown.

The process represented in the diagram produces a molecule that is complementary to the template strand of DNA. What type of molecule is being produced?

• New DNA

• Protein

• messenger RNA
