MULTIPLE CHOICE QUESTION

Which would be the first step in the process that turns a DNA message into a protein?

A section of DNA is  transcribed, or copied into mRNA, messenger  Ribonucleic Acid. mRNA is small enough to leave the nucleus.

The mRNA carries the message  outside the nucleus to a ribosome, the organelle  where proteins are made.

tRNA (transfer RNA) brings the correct amino acids to the ribosome where they join  together to form an amino acid chain and then a  protein.

The two strands of DNA separate at certain  points along the strand and a section of one strand  of DNA is read.

At the ribosome the  message is read three bases at a time. Each set  of three bases corresponds to one amino  acid.
