exam # 4 part 2

What is DNA and what is it made up of?

• A type of protein made up of amino acids

• A double helix molecule made up of nucleotides that stores genetic information

• A single-stranded molecule made up of sugars that stores energy

• A cellular component that facilitates the production of lipids

What are some of the benefits of DNA testing?

• To determine paternity, diagnose disease, and investigate crime scenes

• To create genetic modifications in organisms

• To identify nutritional deficiencies in individuals

• To predict future traits and behaviors of individuals

The nitrogen bases in a DNA molecule are:

• adenine, thymine, cytoplasm, and glucose

• adenine, thymine, cytosine, and guanine

• adenine, thymine, cytosine, and glycol

What is protein folding?

• The process by which a protein breaks down into amino acids

• The process by which a protein goes from being an unfolded polymer to a uniquely structured and active protein

• The replication of DNA to produce new proteins
