What is the purpose of translation? (A) To convert a sequence of DNA into a sequence of mRNA. (B) To convert a sequence of mRNA into a sequence of DNA. (C) To convert a sequence of amino acids into a sequence of RNA nucleotides. (D) To convert a sequence of mRNA into a sequence of amino acids.

In order for a gene in DNA to be converted into a protein, first the messenger RNA, or mRNA, must be formed in a process called transcription. This produces a transcript on which a ribosome and tRNA complex is formed. In a process called translation, the mRNA sequence can be translated into a sequence of amino acids to form a polypeptide.

The answer is thus (D). The purpose of translation is to convert a sequence of mRNA into a sequence of amino acids.
