Cell Cycle
Phase of Mitosis where Chromosomes line up at equator
What is metaphase?
The shape/structure of DNA
What is a double helix?
The protein that synthesizes DNA
What is DNA Polymerase?
The phenomenon that causes chromosomes to break and be put back together wrong, creating variation
What is crossing over?
The cytoplasm divides in this phase of mitosis
What is cytokenesis?
The special structure formed only by cells with cell walls during cytokenesis
What is a cell plate?
The Purpose of DNA
What is to store and encode genetic information?
Protein that separates double helix
What is helicase?
The name for chromosomes that have been put together differently after Prophase I
What are recombinant chromosomes?
The region at the center of each chromosome
What is a centromere?
The cell chooses whether to divide or not in this phase
What is G1
Discovered the structure of DNA
Who are Watson and Crick?
DNA is always synthesized in this direction
What is 5 to 3?
The scientific term for the number of cells created at the end of meiosis
What is haploid?
Proteins that make mammalian cells divide
What are growth factors?
Phase in which the nuclear envelope breaks down and dissapears
What is Prophase?
The rule that states that the number of cytosine should be equal to the number of guanine and the number of adenine should be equal to the number of Thymines
What is Chargaff's Rule?
Pieces of DNA created during synthesis of the lagging strand
What are Okazaki fragments?
Chromosomes separate and migrate to the poles of the cell in this phase
What is Anaphase I
Experiment that proved DNA was the genetic material and not protein
What is the Blender Experiment (Hershey/Chase)
A football shaped structure that facilitates movement of chromosomes during mitosis
What is the miotic spindle?
The difference between purines and pyramidines
What is the number of carbon rings?
They proved DNA replicated semi-conservatively
Who are Meselson and Stahl?
The name for sites where crossing over occurs
What is a chiasma?
The name for the portion of the cell cycle where the cell actually divides.(Includes mitosis and cytokenesis)
What is the miotic phase?
