In RNA, A matches with

• U

• T

• G

• C

In a RNA strand Thymine is replaced with?

• Cytosine

• Gunine

• Uracil

• It's not replaced

Only a portion of DNA, called a gene, is copied into RNA at one time.

• True

• False

After the mRNA is formed, what happens?

• It moves out of the nucleus and into the cytoplasm.

• It binds permanently with DNA molecule.

• It disassembles and the process repeats.

• It moves out of the nucleus and then out of the cell.

What is the copying of mRNA from DNA called?

• translation

• transcription

What is the job of mRNA?

• To take the code out of the nucleus

• To unzip the DNA so it can replicate

• To carry the amino acid to the ribosome

How is mRNA read?

• Three bases at a time.

• A complete strand at a time.

• Three strands at a time.

• One base at a time.

The 3 bases on mRNA is called a

• codon

• anti-codon

Why is tRNA called Transfer RNA?

• Because it is responsible for transferring the protein out of the cell.

• Because it is responsible for transferring the protein building instructions to the ribosome.

• Because it is responsible for transferring the right amino acid to the ribosome to create the protein.
