History of DNA
What is the name of the enzyme used to build DNA molecules
DNA polymerase III
Cells must copy their DNA before they do what?
Cell division
In eukaryotes, where are the copies of DNA made?
Nucleus
Why is deoxyribose called a pentose sugar?
Because it has 5 sides
What contribution did Meselson & Stahl make?
DNA replication is semi-conservative
What is the name of the enzyme that goes back through and seals the broken strands back together?
Ligase
During what part of the cell cycle is DNA copied?
Synthesis phase of Interphase
Adenine - Thymine
Cytosine - Guanine
This is the strand of DNA that is replicated continuously
Leading strand
Name the 3 parts of the nucleotide
What is Phosphate group, 5-carbon sugar, nitrogenous bases
What enzyme proofreads DNA?
DNA polymerase I
What is the complementary DNA strand of CGTATG?
GCATAC
The bond existing between the pentose sugar and the phosphate group
phosphodiester bond
Rosalind Franklin
What are the subunits making up DNA
Nucleotides
What enzyme uncoils DNA so it can be replicated?
Helicase
What type of molecule is put down by the enzyme primase?
RNA
What type of bonds join base pairs on DNA?
Hydrogen Bonds
What did Hersey and Chase use in their experiments to prove DNA was the genetic material?
Bacteriophage
DNA stands for what?
Deoxyribonucleic Acid
Where do new DNA strands grow from?
Replication Fork
The short segments of the lagging strand are called what?
Okazaki fragments
During the termination of the Replication process, when does DNA polymerase detach from the DNA strand?
When it meets a RNA primer or when it meets a replicated DNA strand
