DNA Structure and Function EOC

Like RNA, DNA is a type of:

• Carbohydrate

• Lipid

• Protein

• Nucleic Acid

The subunit of nucleic acids like DNA and RNA are called:

• Monosaccharides

• Sugars

• Amino acids

• Nucleotides

The subunits of nucleic acids, such as DNA, are nucleotides. What are the 3 parts of a nucleotide?

• Phosphate group

• Sugar group

• Hydrogen group

• Nitrogenous Base

What does DNA stand for?

• Double-helix Nucleic Acid

• Deoxyribonucleic Acid

• Dehydrogenic Acid

• Denitrogenous Acid

What type of sugar group does DNA have?

• Ribose

• Glucose

• Deoxyribose

• Lactose

DNA has nitrogenous bases that come in pairs. What is this called?

• Complementary Base Pairing

• Convergent Pairing

• Nondisjunction

• DNA Replication

How many possible bases are found in DNA?

• 1

• 2

• 3

• 4

Select the 2 correct DNA base pairs.

• Cytosine and Guanine

• Cytosine and Thymine

DNA is said to be in the shape of a:

• Single helix

• Double helix

• Plasmid

• Complementary base pairs

Which 2 parts of a nucleotide form the sides or "backbone" of the DNA ladder?
