Front

What is the primary structure of a protein?

Back

The primary structure of a protein is the linear sequence of amino acids linked by peptide bonds.

Front

What type of bonding causes cohesion in water molecules?

Back

Cohesion in water molecules is caused by hydrogen bonding.

Front

In which direction are new nucleotides added during DNA/RNA synthesis?

Back

New nucleotides are added to the 3' hydroxyl end.

Front

What are the three components of a protein monomer?

Back

The three components of a protein monomer are the amine group, carboxyl group, and R group.

Front

Why is water considered a polar molecule?

Back

Water is considered polar due to the presence of polar covalent bonds between oxygen and hydrogen.

Front

What is the difference between primary and secondary protein structure?

Back

Primary structure is the sequence of amino acids, while secondary structure refers to the folding or coiling of the amino acid chain into alpha helices or beta sheets.

Front

What role do hydrogen bonds play in the properties of water?

Back

Hydrogen bonds contribute to water's high surface tension, cohesion, and adhesion properties.

Front

What is the significance of the R group in amino acids?

Back

The R group determines the specific characteristics and properties of each amino acid, influencing protein structure and function.

Front

What is the function of the carboxyl group in amino acids?

Back

The carboxyl group acts as an acid, donating a proton (H+) and contributing to the overall charge of the amino acid.

Front

What is the role of nitrogenous bases in nucleic acids?

Back

Nitrogenous bases are essential for encoding genetic information in DNA and RNA.
