RNA and Protein Synthesis

What is the role of mRNA in protein synthesis?

• it makes the bases that makes up DNA

• it converts (translates) the code in DNA into a protein

• it helps DNA perform replication

• it makes the amino acids used in protein synthesis

Where is mRNA made?

• in the nucleus

• in the ribosome

• in the mitochondria

• in the vacuole

The long string of bases at the bottom of the diagram is

• tRNA

• mRNA

• an anticodon

• an amino acid

The blue structure in this diagram is

• an anticodon

• DNA

• part of the ribosome

• tRNA

The job of tRNA is to

• copy the genetic code from DNA

• bring amino acids to the ribosome

• bring the code from the DNA to the ribosome

• synthesize amino acids

Ribosomal RNA is a form of RNA that

• makes up a ribosome

• carries amino acids to the ribosome

• transfers the genetic code to the nucleus

• copies the genetic code from DNA

Which nitrogen base is not a part of RNA molecules?

• thymine

• uracil

• adenine

• cytosine

• guanine

In order for protein synthesis to occur, mRNA must leave the nucleus and travel to

• a ribosome in the cytoplasm

• a mitochondria in the cytoplasm

• a vacuole in the cytoplasm

• a chloroplast in the cytoplasm
