Bio Exam 3 Questions and Answers 100% Pass What did Griffith discover in his experiment involving bacteria with capsule (S) and non-capsule (R) strains, and what molecule did Avery, MacLeod, and McCarty identify as responsible for this phenomenon? Griffith observed that DNA could transform bacteria, demonstrating for the first time that genetic material can be transferred through a process called transformation. The S-strain, with a polysaccharide capsule, is protected from the immune...

What enzymes are involved in DNA replication? - ANSWER-DNA dependent DNA polymerase is DNA replication anabolic or catabolic - ANSWER-anabolic what were the 3 competing models of DNA replication - ANSWER-- semiconservative - conservative - dispersive semiconservative DNA replication - ANSWER-each daughter DNA molecule is composed of one original strand and one new strand conservative DNA replication - ANSWER-- the parent strands separate and act as templates - then the original parent...

GCD Ch. 6 Exam Questions with Correct Answers The process of DNA replication requires that each of the parental DNA strands be used as a ___________________ to produce a duplicate of the opposing strand. A) catalyst B) competitor C) template D) copy - Answer-C) template DNA replication is considered semiconservative because ____________________________.

Briefly explain how the base pairs A-T and C-G bond to each other and why the interactions they form are important to DNA unwinding. Base pairs form hydrogen bonds to each other. G and C form 3 hydrogen bonds, while A and T form 2 hydrogen bonds. These hydrogen bonds are weak electrostatic interactions that are able to hold the DNA together but are easily broken for the DNA to unwind. Why are telomerase inhibitors an attractive prospect for cancer therapies? >90% of cancer cells expres...
