What is the role of R-groups in protein structure?

Back

R-groups (side chains) determine the chemical properties of amino acids, influencing protein folding and function.

Front

What is the consequence of a single amino acid substitution in a protein?

Back

A substitution can lead to misfolding and loss of function if the new amino acid has different properties.

Front

What is the significance of phosphorus in plant growth?

Back

Phosphorus is essential for synthesizing nucleic acids and lipids, which are crucial for cell growth and energy transfer.

Front

What is the process of dehydration synthesis?

Back

Dehydration synthesis is the process where monomers are joined by covalent bonds, releasing a water molecule.

Front

How do starch and cellulose differ in structure?

Back

Starch and cellulose are both composed of glucose monomers, but in cellulose, every other glucose is rotated 180 degrees.

Front

What distinguishes RNA from DNA at the molecular level?

Back

RNA contains ribose sugar and has uracil instead of thymine, while DNA contains deoxyribose and thymine.

Front

What is the function of nucleic acids in cells?

Back

Nucleic acids (DNA and RNA) store and transmit genetic information, guiding protein synthesis.

What is the importance of protein folding?

Back

Proper protein folding is crucial for biological function; misfolded proteins can lead to diseases.

Front

What are macromolecules?

Back
