Basic unit (monomer) of DNA.
What is a nucleotide?
The enzyme responsible for unwinding the DNA.
What is helicase?
The main phases of the cell cycle.
What is interphase, mitosis, and cytokinesis?
The purpose of mitosis.
What is to divide the nucleus and its contents?
The primary purpose of meiosis.
What is to produce gametes (sperm and eggs)?
The four Nitrogenous Bases of DNA.
What are adenine, thymine, cytosine, and guanine?
The direction new nucleotides are added and DNA is read.
What is 5' to 3'?
What is the cell grows, duplicates its DNA, and prepares for division?
Name the phases of mitosis in order.
What are prophase, metaphase, anaphase, and telophase?
The number of divisions that occur in meiosis.
What is two divisions?
Shape of DNA molecule.
What is a double helix?
The enzyme responsible for proof reading new DNA strands.
What is DNA polymerase?
The role of checkpoints in the cell cycle.
What is to ensure that the cell is ready to proceed to the next phase and prevent cancer?
Anaphase
What is sister chromatids are pulled apart to opposite ends of the cell?
The difference between meiosis I and meiosis II.
What is meiosis I reduces the chromosome number by half, while meiosis II separates sister chromatids?
The role of hydrogen bonds in DNA Structure.
What holds the two strands of DNA together at the nitrogen bases?
The main function of DNA Polymerase.
To build new DNA by adding nucleotides to existing strands.
The longest phase pf the cell cycle.
What is interphase?
The type and number of cells produced in mitosis.
What is two identical diploid daughter cells?
Crossing over, and why it is important.
What is the exchange of genetic material between homologous chromosomes, increasing genetic diversity?
What is the sequence (order) of nitrogen bases.
The reason why there is a leading strand and a lagging strand. (Direction of the two strands of DNA)
What is anti-parallel?
Uncontrolled cell growth.
What is cancer?
The reason why mitosis is important to growth and repair.
What is it allows for the replacement of damaged or dead cells?
How meiosis contributes to genetic variation.
What is through independent assortment and crossing over during gamete formation?
