DNA: Part 1

What is a macromolecule?

• A large molecule that is made up of smaller units

• A really small molecule that helps to make up larger units

What are nucleotides?

• The building blocks of DNA

• Each strand of DNA

• Basically the same thing as amino acids

• Bacteria that infect viruses

Which of the following are the basic components of a nucleotide? Select all that apply.

• Deoxyribose

• Phosphate group

• Nitrogenous base

• Hydrogen group

What is deoxyribose?

• A type of sugar

• A type of nitrogenous base

• The name of the model of DNA

What are the nitrogenous bases of DNA? Select all that apply.

• Adenine

• Cytosine

• Guanine

• Thymine

Which component (s) of the DNA molecule make up the backbone of the structure?

• Nitrogenous bases

• Deoxyribose

• Phosphate group

Which component (s) of the DNA molecule make up the interior of the structure (are found inside of the 2 backbones)?

• Nitrogenous bases

• Deoxyribose

• Phosphate group

What determines the genetic code of DNA?

• Sequence of nitrogenous bases

• Sequence of deoxyribose

• Sequence of phosphate groups
