KU BIOL 600 EXAM 1 REVIEW 2025
QUESTIONS AND ANSWERS
DNA is made from the building blocks adenine, guanine, cytosine, and... - ANS thymine
The number of hydrogen bonds formed between A and T - ANS 2
The number of hydrogen bonds formed between C and G - ANS 3
The cellular process of synthesis of RNA from DNA template is called - ANS Transcription
....are cells which are composed of multiple specialized membrane-bound
compartments. - ANS Eukaryotic cells
Broad class of biological macromolecules that are hydrophobic and function as membrane
barrier, signaling molecules, and fuel storage, among others - ANS lipids
Cellular organelle where glycosylation occurs. - ANS Golgi apparatus
Organelle that can be 'rough' or 'smooth' and is responsible for protein processing and
xenobiotic metabolism - ANS endoplasmic reticulum (ER)
Organelle filled with proteases and other digestive enzymes - ANS lysosome

, What are the four key classes of biomolecules? - ANS proteins, nucleic acids (DNA/RNA),
carbohydrates, and lipids
How do eukaryotic cells differ from prokaryotic cells? - ANS eukaryotic cells have membrane-
bound organelles, prokaryotic cells do not
Draw a diagram for the central dogma of biology - ANS
What two classes of biomolecules are capable of catalysis? - ANS proteins and RNA
Which biomolecules are chiefly responsible for catalysis of cellular processes? - ANS proteins
DNA and RNA are composed of what basic biochemical compounds? - ANS nucleotides
...weak interaction between water molecules. - ANS hydrogen bonding
Which type of amino acids are responsible for increasing entropy as a protein folds. -
ANS hydrophobic/nonpolar amino acids
Using Coulomb's law, describe how water is an ideal solvent for the ions found in cells? -
ANS Water has a high D, dielectric constant, which makes F lower. F is the force needed to
dissolve ions with charges q1 and q2
What is the significance of hydrogen bonding in biochemical structures such as DNA? -
ANS The weak nature of H bonds (compared to covalent bonds) allow the two DNA strands
to be 'unzipped' during replication, and to reform again, with less energy
