During which phase of the cell cycle does DNA replication occur?

• G1
• S
• G2
• M

What is the purpose of DNA replication?

• Cut the DNA 
• Make more cells
• Apoptosis
• Duplicate the DNA

What unzips the DNA strand?

• Telomere
• Helicase
• Replication Fork
• DNA

___________ is to DNA and _______ is to RNA

• Ribose / Deoxyribose
• Phosphodiester bonds / 2' Hydroxyl group
• Nucleotides / Nucleosomes
• Deoxyribose / Ribose

If DNA Polymerase is reading the following sequence: 3'-AATCGC-5' what will the enzyme add to the growing DNA strand?

• 5'-GCGATT-3'
• 5'-TTAGCG-3'
• 5'-AATCGC-3'
• 3'-AATCGC-5'

What is mRNA?

• with proteins, makes up ribosomes; most abundant type of RNA
• the coding region; the parts of a gene that are expressed 
• Encodes genetic information from DNA and transports it to ribosomes; where information is translated into amino acid sequences 
• functions as an interpreter in translation; picks up amino acid and transfers it to the right codon 

What is tRNA?

• Encodes genetic information from DNA and transports it to ribosomes; where information is translated into amino acid sequences 
• functions as an interpreter in translation; picks up amino acid and transfers it to the right codon 
• with proteins, makes up ribosomes; most abundant type of RNA
• the coding region; the parts of a gene that are expressed

An enzyme that links together the growing chain of RNA nucleotides during transcription, using a DNA strand as a template.

• RNA Splicing
• RNA polymerase
• Uracil
• mRNA

On a tRNA molecule, a specific sequence of three nucleotides that is complementary to a codon triplet on mRNA.

• Anticodon
• Stop codon 
• rRNA
• Promoter
