The process of using the information in mRNA to make a protein is known as -

• Translation

• Transcription

Scientists can use a single codon chart to translate the information in a strand of mRNA from any species because:

• Scientists only study a few related species.

• The codon chart can adjust to any species.

• Every species uses the same genetic code.

• All species make the exact same proteins.

Like most cellular processes, transcription is directed by the action of –

• enzymes

• fatty acids

• monosaccharides

• inhibitors

Choose the sequence of the mRNA strand that would match up with to the following DNA strand:

GTACAT

• CATGTA

• GAUCUA

• CAUGUA

• CUTGTU

How many nucleotides code for 1 amino acid?

• 1

• 2

• 3

• 4
