Unit 6 - Lesson 1

What does DNA stand for?

• Deoxyribonucleic Acid
• Deoxyribonucleic Base
• Deoxyribonitric Acid
• Dioxyribonucleic Acid

What kind of shape does a DNA have?

• Single strand
• Circular
• Double helix
• Square

Since DNA is a polymer for Nucleic Acids, what is the monomer?

• Amino Acid
• Nucleotide
• Monosaccharide
• Fatty Acid

What are the THREE parts of a Nucleotide?

• Amino acid, fatty acid, glycerol
• Carbohydrate, protein, lipid
• Enzyme, cofactor, substrate
• A sugar, a phosphate group, and a nitrogenous base

What are the FOUR types of Nitrogenous Bases in DNA?

• Thymine, Uracil, Cytosine, Glutamine
• Adenine, Guanine, Cytosine, Serine
• Adenine, Guanine, Cytosine, Thymine

• Adenine, Thymine, Guanine, Alanine

Which of the following are the proper pairings of nitrogenous bases?

• A-T and C-G
• A-G and C-T
• G-T and C-A
• A-C and T-G

What process in involves the process of copying or duplicating DNA before cell division. ?

• DNA transcription
• Protein synthesis
• Cell division
• DNA replication

What are the FOUR key players that are mainly involve in DNA Replication?

• DNA ligase, RNA polymerase, exonuclease, topoisomerase
• DNA helicase, RNA primase, ligase, telomerase
• DNA polymerase, RNA helicase, primase, nuclease
• Helicase, DNA polymerase, primase, ligase

There are four different enzymes in charge of DNA Replication.

Which do you call the UNZIPPING enzymes by breaking through hydrogen bonds that holds the nitrogenous bases?

• helicase
• ligase
• polymerase
• nuclease

There are four different enzymes in charge of DNA Replication.

Which do enzyme is in charge of replicating DNA Molecules to actually build a new strand of DNA?

• helicase
• ligase
• DNA Polymerase

• nuclease
