8
Who provided strong evidence for the semi (X) of DNA? X = Conservative, Dispercive, Urasive, Ao
Rosalind Franklin
Meselson and Stahl

9
What splits the DNA?
Helixase
Helicase
Helixaze
Helicaze
10
Why are fragments produced during replication of DNA?
so helicase can add nucleotides
DNA polymerase can only add to 3' end
DNA is produced 3 ' to 5'
so covalent bonds form between bases

DISPERSIVE
SEMI-DISPERSIVE
CONSERVATIVE
12
What is Complementary base pairing?
Adenine + Pyrimidine
Pyrimidine + Pyrimidine
Purine + Pyrimidine fit together
Purine + Purine fit together
13
WHAT IS TRANSCRIPTION?
THE MAKING OF Protein
THE MAKING OF mRNA
THE MAKING OF tRNA
THE MAKING OF HUMAN BABIES
14
What does DNA Ligase Do?
Joins Lagging strand together
Separates the DNA into two separate strands
Removes the RNA Primase, and replaces it with DNA
Add's a DNA Primer
15
What did Meselson and Stahl conclude
translation occurs at the ribosome
DNA replication is conservative
transcription occurs in the nucleus
DNA replication is semiconservative
16
Which of these is a Pyramidine?
Melanine
Uracil
Adenine
Guanine
17
