BIO 105 EXAM 3 CORE NATURAL SELECTION
AND POPULATION DYNAMICS REVIEW 2026
◉ lysogenic life cycle
Answer: integrate directly into host cell genome and delay its own
reproduction until a later time. 1. Attachment > 2. Penetration > 3.
Biosynthesis > 4. Maturation > 5. Release
◉ capsid
Answer: Outer protein coat of a virus
◉ H & N Spikes
Answer: theyre made of glycoprotein (protein w a sugar attached)
and assist the virus in identifying and entering its host cell
◉ antigen
Answer: a toxin or other foreign substance that induces an immune
response in the body, especially the production of antibodies.
◉ antigentic drift
Answer: loss of original genetic diversity (bottleneck effect &
founder effect)
, ◉ bottleneck effect
Answer: A change in allele frequency following a dramatic reduction
(random event) in the size of a population
◉ founder effect
Answer: change in allele frequencies as a result of the migration of a
small subgroup of a population
◉ RNA polymerase involvement in virus evolution
Answer: replicate the genome and carry out transcription
◉ Where did Darwin sail during his voyages as a naturalist?
Answer: the galapagos
◉ Where did Wallace travel as he made his observations of
organisms?
Answer: Brazil (Malay Archipelago)
◉ What was the status of Darwin and Wallace's relationship and
thoughts on Natural selection?
Answer: Their work was presented alongside each others and they
helped each other with their discoveries
