BIO 100 EXAM 5 QUESTIONS &
ANSWERS 100% CORRECT
Avery, Macleod, McCarty - ANSWERUsed specific enzymes to degrade different
components in heat-killed S strain. Discovered that DNA must be the transforming
material
Hershey & Chase - ANSWER"Blender experiment", using T2 bacteriophage.
Established that the viral DNA enters bacterial cells and is required for synthesis of
new viral particles
DNA polymerases - ANSWEREnzymes that make the covalent bonds between the
nucleotides of a new DNA strand and help repair DNA that has been damaged by
toxic chemicals or high-energy radiation, such as X-rays and ultraviolet light
origins of replication - ANSWERWhere does DNA replication begin?
Replication bubbles - ANSWERDNA replication proceeds in both directions, creating
what?
transcription - ANSWERthe transfer of genetic information from DNA into an RNA
molecule
DNA, not protein is the genetic material that bacteriophages use to make new virus
particles - ANSWERWhat did Hershey and Chase discover?
X-ray diffraction patterns - ANSWERWhat did Maurice Wilkins and Rosalind Franklin
provide?
0.34 nm - ANSWERBases are stacked at what intervals?
Crick, Watson, and Wilkins - ANSWERWho received the Nobel prize of physiology or
medicine
Frederick Miescher - ANSWERFirst described DNA & RNA & isolated a phosphorus
material from the nuclei of white blood cells and called it "nuclein"
Frederick Grifith - ANSWERTransformation experiments, established that a
"principle" carries the necessary information for bacterial transformation, R/S cells -
the "transforming agent" was still active in the dead "S" strain
Unwinding - ANSWERWatson and Crick recognized that the double stranded DNA
would replicate by doing that?
Semiconservative - ANSWERThe mode of replication
