BIMM 100 Exam 1 questions and
correct answers
Griffith Expt. - correct answer ✔✔ Mouse/heat killed s strain expt;
Found that bacteria can transfer genetic material; raised question of what that genetic material
was
Avery, Mccarthy, Macleod - correct answer ✔✔ DNA was the transferred genetic material
Beadle and Tatum - correct answer ✔✔ one gene-one polypeptide
-Arginine synthesis pathway
-one gene encoded one enzyme in pathway
Central Dogma - correct answer ✔✔ DNA (transcription via RNA polymerase)--->RNA
(translation via Ribosomes)--->Protein
Meselson-Stahl Expt. - correct answer ✔✔ Found out that DNA was replicated SEMI-
CONSERVATIVELY;
be able to draw out semi-conservative and conservative replication for two generations
How does replication machinery know where and when to start? - correct answer ✔✔
WHERE=Origin of Replication
HOW= pre-Replication complex (marks Origin of Replication) in G1
How many Origin of replications do Bacteria have? Eukaryotes? - correct answer ✔✔ Bac.-
Single Origin
