In order for protein synthesis to occur, both transcription and translation must occur. Which of the following statements describes the difference between transcription and translation?

In transcription, the genetic code of a DNA molecule is first encoded. Translation is the process of concerting the DNA code into code that RNA can use.

In transcription, an amino acid chain is encoded in a DNA molecule. Translation is the process of turning the amino acids into nucleic acids in an RNA molecule.

In transcription, a double helix DNA molecule is split into two separate single strands. Translation is the process of joining each single DNA strand with a single strand of matching RNA.

In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. Translation is the process of creating an amino acid chain using the encoded messenger RNA.
