Protiens called helicases.

They allow for other proteins to make mRNA strands from the DNA template and are also used when DNA replicates.

What are the phases of transcription?

Initiation - Polymerase III, binds and unwinds DNA, transcription begins. Elongation - Base pairng occurs polymerase I, binds the new strands of mRNA. Termination - New mRNA released.


What does DNA start with?

There are two steps to protein synthesis: 1. Transcription - DNA unwinds, mRNA is made on the DNA template, the mRNA leaves the nucleus (through the nuclear pores) and goes to the ribosomes. 2. Translation - The mRNA moves along the ribosome where the information in the mRNA (codons) give the instructions for the sequence of amino acids in the protein that is being made. Once the amino acid sequence (protein, or "polypeptide") is complete, it detaches from the ribosome.
