How is RNA different from DNA?

• It contains the nitrogen base cytosine
• It has a sugar and phosphate backbone
• It's single stranded
• All of these are difference

Which molecule is directly copied from DNA and then leaves the nucleus after transcription?

• mRNA
• tRNA
• rRNA
• DNA

Which enzyme is responsible for matching the mRNA bases to the DNA template during TRANSCRIPTION?

• DNA Ligase
• Binding Protein
• DNAPolymerase
• RNA Polymerase

Anticodons are attached to which molecule?

• mRNA
• tRNA
• rRNA
• DNA

Three mRNA bases that are read together are known as what?

• Codon
• Anticodon
• Triplet
• Amino acid

Which of the following would be the transcribed mRNA complement to the DNA bases TCG ACT?

• AGC TGA
• TCG ACT

What stops the process of translation?

• DNA polymerase just stops adding bases
• mRNA transcript falls apart
• A stop codon is reached
• The ribosome moves on to another protein

What are the individual units (monomers) that make up a protein?

• amino acids
