BIO 210 MOCK EXAMS QUESTIONS AND
ANSWERS SURE A+
✔✔Nucleic acids - organic compound - ✔✔DNA, RNA
✔✔DNA nitrogenous bases - ✔✔Adenine, Guanine, Cytosine, Thymine (AGCT)
✔✔RNA nitrogenous bases - ✔✔Adenine, Guanine, Cytosine, Uracil (AGSU)
✔✔Plasma Membrane - ✔✔Phospholipid bilayer composed of hydrophilic (phosphate)
heads and hydrophobic (lipid) tails
✔✔Resting membrane potential - ✔✔maintained by sodium potassium pump (active
transport) - takes 3 sodium out and 2 potassium in
✔✔K+ Potassium - ✔✔10 times higher inside the cell - major intracellular cation
✔✔Na+ Sodium - ✔✔10 times higher outside the cell - major extracellular cation
✔✔passive transport - osmosis - ✔✔Movement of water. Water follows salt, thats what
makes it move
✔✔Hypotonic solution - ✔✔cells lyse/burst
✔✔Isotonic solution - ✔✔no change
✔✔Hypertonic solution - ✔✔cell shrink
✔✔cell cycle - ✔✔before a cell can divide, it's DNA has to be replicated exactly
✔✔3 stages of interphase - ✔✔G1 - Growth and metabolism
S - DNA replication
, G2 - Preparation for division
✔✔Cell Division - Mitosis - ✔✔4 Phases
Prophase
Metaphase
Anaphase
Telophase
✔✔Prophase - ✔✔chromosomes appear
✔✔Metaphase - ✔✔chromosomes cluster in the middle
✔✔Anaphase - ✔✔daughter chromosomes appear
✔✔Telophase - ✔✔identical sets of chromosomes at opposite poles; cleavage furrow
✔✔Cytokinesis - ✔✔complete division of the cell
✔✔Protein synthesis - Transcription - ✔✔DNA's information is encoded by a codon in
mRNA. Happens in the nucleus
✔✔Protein synthesis - Translation - ✔✔Information carried by the mRNAis decoded by
an anticodon and used to assemble polypeptides. Happens in the cytosol/ribosome
✔✔Tissues - ✔✔Groups of cells similar in structure that perform a specific function
✔✔Epithelial Tissue - ✔✔a sheet of cells that cover a body surface or lines a cavity
✔✔Connective Tissue (CT) - ✔✔CT Proper - fibroblasts
Cartilage - chondrocytes
Bone - Osteocytes
Blood - erythrocytes and leukocytes and platelets
✔✔Muscle tissue - ✔✔skeletal muscle
Cardiac muscle
smooth muscle
✔✔nervous tissue - ✔✔neurons
neuroglia
✔✔Glandular epithelia - Endocrine - ✔✔ductless glands that secrete directly into the
bloodstream. Product does not leave the body (hormones)
