DNA Structure
List the parts of a nucleotide
phosphate, sugar, and base?
The flow of information. DNA--> RNA --> Protein
The 4 phases of mitosis.
Prophase, Metaphase, Anaphase, Telophase
Purpose of meiosis
Reduce chromosome number in half, which leads to gametes
This is used to identify certain genetic disorders in which there are extra or too few chromosomes
Karyotype
List the bases that are compliments with each other.
Adenine and Thymine. Cytosine and Guanine.
Describe the term. Semi-Conservative
Two copies of DNA that each contain one of the original parent strands of DNA and one new daughter strand.
The three steps of interphase.
G1, S, G2
The random separation of the homologous chromosomes
Independent Assortment
The three cell cycle checkpoints.
G1, G2, M
These bases are purines.
Adenine and Guanine.
The end result of DNA replication.
A copy of DNA
Sister chromatid separate to opposite sides of the cell
Anaphase
The random exchange of genetic material
Crossing Over
When spindle fibers fail to attach to homologous chromosomes or sister chromatid. This leads to abnormal gametes
Non-disjunction
Hydrogen bonds
Unzips and unwinds DNA strand by breaking the hydrogen bond
This occurs during the S phase of Interphase
DNA is replicated
Homologous Chromosomes separate in these step
Anaphase 1
The protein that controls the cell cycle by acting like checkpoints
Cyclines
A DNA sequence has 13% thymine. Estimate the amount of adenine, cytosine, and guanine.
Cytosine - 37%
Guanine - 37%
The function of DNA polymerase
Adds complementary nucleotides to exposed strands
List three characteristics of the products of mitosis.
2 cells produced, genetically identical, 2n nuclear state, 46 chromosomes, Somatic cells
List three characteristics of the products of meiosis.
4 cells made, genetically unique, n nuclear state, 23 chromosomes, gametes.
