Mitosis, Meiosis, And Cystic Fibrosis Flashcards
What is the function of mitosis?
Produce cell growth & tissue repair
What is the function of meiosis?
Introduces genetic variability
How many cell division are in mitosis?
Two diploid cells (2n)
How many cell division are in meiosis?
4 each haploid (n)
How many cells in mitosis are produced?
46 cells
How many cells are produced in meiosis?
23 cells
What types of cells are in mitosis?
Diploid
What types of cells are in meiosis?
Haploid
What are genetics are the new cells in mitosis?
Identical cells
What are the genetics are new cells in meiosis?
Unique
One of two identical copies of each chromosomes, linked at centromere
Sister chromatid
One chromosome of each homologous pair comes from the mother and one comes from the father, they are similar, but not identical. Each carries the same gene in the same order, but the alleles for each trait may not be the same.
Homologous chromosomes
A complex of DNA and protein.
Chromatin
A point of constriction on the chromosome containing repeated DNA sequences that bind to specific protein.
Centromere
During mitosis when does DNA replication occur?
Interphase I
What holds the sister chromatids together in your representation? And what is the protein that does this within the cell?
Centromere, cohesion the protein
In agarose gel in electrophoresis, where do the DNA samples migrate towards through the gel?
Positive electrode
What causes the the DNA samples to migrate to the positive electrode?
Due to their inherent negative charge.
What is the rate of migration through the gel caused by?
The size of the DNA
What size of pieces moves quickly through the gel?
Smaller pieces of DNA migrate quickly
What did we conclude the genotype for Nancy?
Both carriers.
