DNA structure
The letters DNA represent this
What is Deoxyribonucleic Acid?
This is the process by which one type of bacteria is changed into another type.
What is transformation?
In eukaryotes, this is where the copies of DNA are made?
What is the Nucleus?
This is the enzyme that unzips and unwinds the DNA strands.
What is Helicase?
This uses the RNA primer to synthesize the daughter DNA strand.
What is DNA polymerase III?
These are the monomers of DNA?
What are Nucleotides?
These researchers used radioactive markers in experiments to show that DNA was the genetic material in cells.
Who are Hershey and Chase?
DNA replication is important before cells undergo this process.
What is Cell division?
This is the strand of DNA that is replicated continuously
What is the Leading strand?
This is the enzyme that seals the gaps between the Okazaki fragments.
What is Ligase?
Name the 3 parts of the nucleotide
What is a Phosphate group, a 5-carbon sugar, and a nitrogenous base?
This is the scientist whose X-ray crystallography technique resulted in photographs of the X-ray diffraction pattern of DNA.
Who is Rosalind Franklin?
When one strand of DNA runs 5' to 3' while the other strand runs 3' to 5'.
What is anti-parallel?
This is the direction that DNA polymerase adds the new nucleotides.
What is the 5' to 3' direction?
This is the enzyme that replaces the RNA primer
What is DNA polymerase I?
Adenine - Thymine
Cytosine - Guanine
This scientist is famous for discovering the 4 nucleotide building blocks and how they pair.
Who is Erwin Chargaff?
The type of bonds that hold A to T and C to G.
What are hydrogen bonds?
This is the strand that is slower to replicate because it must be synthesized discontinuously in short fragments.
What is the lagging strand?
This is what keeps the replication forks from rejoining.
What are Single-stranded binding proteins?
What is the complementary DNA strand of CGTATG?
GCATAC
These two scientists were awarded the 1962 Nobel Prize in Physiology or Medicine for their discovery of the double-helical structure of DNA.
Who are James Watson and Francis Crick?
This makes up the backbone of the DNA strands.
What are phosphate and sugar?
These are the short, newly synthesized DNA segments on the lagging strand during DNA replication.
What are Okazaki fragments?
This is the enzyme that prevents the over-winding of the DNA double helix ahead of the replication fork.
What is Topoisomerase?
