• help with RNA splicing
• make up ribosomes

What type of RNA moves to the ribosome to start protein synthesis?

• tRNA

• mRNA

• rRNA

Why must transcription occur where DNA can be found?

• because DNA can't leave

• because ribosomes are in the nucleus

• because DNA polymerase is found there

• because helicase unzips the DNA
