Front

What is an ionic bond?

Back

An ionic bond is formed when one atom gives up an electron to another, resulting in oppositely charged ions that attract each other.

Front

What process do monomers undergo to form polymers?

Back

Monomers combine to form polymers through the process of dehydration synthesis.

Front

What distinguishes nucleic acid #1 from nucleic acid #2?

Back

Nucleic acid #1 contains adenine-thymine base pairs, whereas nucleic acid #2 does not.

Front

What is cohesion in the context of water?

Back

Cohesion is the tendency of water molecules to 'stick' to each other due to hydrogen bonding.

Front

What is adhesion in the context of water?

Back

Adhesion is the tendency of water molecules to 'stick' to other compounds and surfaces.

Front

Define dehydration synthesis.

Back

Dehydration synthesis is a chemical reaction that involves the removal of water to join two molecules together.

Front

Define hydrolysis.

Back

Hydrolysis is a chemical reaction that involves the addition of water to break down a compound into smaller molecules.

Front

What are purines and pyrimidines?

Back

Purines are nitrogenous bases with a double-ring structure (adenine and guanine), while pyrimidines have a single-ring structure (cytosine, thymine, and uracil).

Front

What is the role of phosphate groups in nucleic acids?

Back

Phosphate groups are part of the backbone of nucleic acids and are involved in linking nucleotides together.

Front

What is the significance of ribose and deoxyribose sugars in nucleic acids?

Back

Ribose is found in RNA, while deoxyribose is found in DNA; the difference is that deoxyribose lacks one oxygen atom.
