WHAT IS THE DIFFERENCE BETWEEN PROKARYOTIC AND
EUKARYOTIC DNA - CORRECT
ANSWER - PROKARYOTIC DNA IS SMALL
AND CIRCULAR EUKARYOTIC DNA IS LONG
AND LINEAR
WHAT ENABLES DNA REPLICATION TO OCCUR AS
QUICKLY AS IT DOES IN EUKARYOTES (THE ENTIRE
HUMAN GENOME CAN BE REPLICATED IN 8 HOURS)? -
CORRECT ANSWER - EUKARYOTES HAVE MULTIPLE
REPLICONS (REPLICATION FORKS)
,WHAT ARE THE NAMES AND FUNCTIONS OF THE
ADDITIONAL DNA POLYMERASES USED DURING
EUKARYOTIC DNA REPLICATION? - CORRECT ANSWER -
POLYMERASE ALPHA- SYNTHESIzES RNA PRIMERS ON
LEADING AND LAGGING STRANDS (LOW PROCESSIVITY
SO IT DISSOCIATES QUICKLY)
POLYMERASE EPSILON- GREATER PROCESSIVITY THAN
ALPHA; 3'-5' EXONUCLEASE ACTIVITY( DELETES
MISTAKES AND SYNTHESIzES RNA PRIMERS ON THE
LEADING STRAND)
POLYMERASE DELTA- GREATER PROCESSIVITY; 3'-5'
EXONUCLEASE ACTIVITY; SYNTHESIzES
RNA PRIMERS ON THE LAGGING STRAND
WHAT HAPPENS DURING THE INITIATION STAGE OF DNA
REPLICATION IN EUKARYOTES? -
CORRECT ANSWER -
EXPLAIN WHAT GRIFFITH'S TRANSFORMATION
EXPERIMENT IS AND THE RESULTS OF THE EXPERIMENT.
,- CORRECT ANSWER - GRIFFITH EXPERIMENTED WITH
VIRULENT AND ANTIVIRULENT STRAINS OF PNEUMONIA.
HE OBSERVED THAT WHEN HEAT-KILLED VIRULENT
STRAINS WERE PLACED IN CLOSE PROXIMITY TO LIVE
ANTI-VIRULENT STRAINS, THE ANTIVIRULENT STRAINS
WOULD BECOME VIRULENT. THIS LED HIM TO PROPOSE
THE EXISTENCE OF SOME MATERIAL BEING ABLE TO BE
PASSED BETWEEN ORGANISM THAT WOULD
GENETICALLY ALTER THE ORGANISM.
EXPLAIN WHAT THE AVERY AND MCLEOD EXPERIMENT
WAS AND HOW IT EXPANDED ON WHAT GRIFFITH
DISCOVERED WITH THE TRANSFORMING PRINCIPLE. -
CORRECT ANSWER - THIS EXPERIMENT BEGAN BY
RUNNING PRELIMINARY TESTS ON THE PHYSICAL
PROPERTIES OF THE TRANSFORMING PRINCIPLE, RULING
OUT LIPIDS AND CARBOHYDRATES. THEN, THEY ADDED
ENzYMES TO DESTROY EITHER PROTEINS, RNA, OR DNA
TO SEE IF, WHEN INjECTED WITH THE TRANSFORMED
STRAIN USED IN GRIFFITH'S EXPERIMENT, IF THE MOUSE
WOULD STILL DIE. THEY CONCLUDED THAT DNA WAS THE
TRANSFORMING PRINCIPLE OBSERVED BY GRIFFITH
, EXPLAIN WHAT THE HERSHEY-CHASE EXPERIMENT WAS
AND HOW IT CEMENTED DNA AS THE HEREDITARY
MATERIAL RESPONSIBLE FOR THE TRANSFORMING
PRINCIPLE - CORRECT
ANSWER - HERSHEY AND CHASE USED
BACTERIOPHAGES INjECTED WITH RADIOACTIVE
SULFUR (TO TEST PROTEINS) OR RADIOACTIVE
PHOSPHORUS (TO TEST NUCLEOTIDES) TO SEE, AFTER
INFECTION, WHETHER THE INFECTED CELLS WOULD BE
RADIOACTIVE. THEY USED A CENTRIFUGE TO ISOLATE
THE PROTEIN SHELLS FROM THE NUCLEIC ACIDS. THE
PELLET AT THE BOTTOM FOR THE TEST RAN WITH
RADIOACTIVE SULFURE SHOWED THE SUPERNATANT
THE PELLET WAS IN TO BE MORE RADIOACTIVE AND THE
TEST WITH THE PHOSPHORUS SHOWED THE PELLET TO
BE MORE RADIOACTIVE. THIS SUGGESTED THAT DNA
WAS THE TRANSFORMING PRINCIPLE
IDENTIFY THIS PART OF THE CHROMOSOME - CORRECT
ANSWER - P-ARM
IDENTIFY THIS PART OF THE CHROMOSOME - CORRECT
ANSWER - Q-ARM
