Mitosis is to ____ reproduction as meiosis is to ____?
Asexual; Sexual
What is kinetochore?
Difference between somatic cells and germ line cells?
What is "Germline cells are reproductive cells (eggs and sperm) and somatic are all the other cells in the body (bone, muscle, nervous...)"?
Mitosis produces (2)___ daughter cells; while meiosis produces (4)__ daughter cells.
What is identical ; not identical
2 homologous chromosomes that are attached together are called
Tetrad
Chromosomes condense and attatch to spindle via kinetochore
Nucleolus and nuclear membrane disappear
What is Prophase?
Chromosomes align on equatorial plane of cell
Chromosmes decondense and nuclear membranes form
What is Telophase?
Sister chromatids of each duplicated chromosome move to opposite poles of the cell
What is anaphase?
One set of chromosomes (23) is considered ___; 2 sets of chromosomes (46) are considered ___
What is haploid and diploid?
Paired chromosomes align on the equatorial plane in the cell; chiasmata move towards telomeres
What is Metaphase 1?
Chromosome movement is completed and new nuclei begins to form
What is Telophase 1?
Homologous chromosomes disjoin and move to opposite poles of the cell
What is Anaphase 1?
The most complex length of meiosis 1 divided into 5 separate steps
Anaphase (mitosis) and anaphase 2 separate _______; while anaphase 1 separates___
What is sister chromatids ; homologous chromosomes?
Chromosomes condense and become longer
What is leptonema?
Paired chromosomes condense even further and become attatched to spindle fibers
What is diakinesis?
Homologous chromosomes are fully paired --> tetrad
crossing over occurs!!
What is pachynema?
Homologous chromosomes separate slightly, except at chiasmata.
What is diplonema?
What is Leptonema -> Zygonema -> Pachynema -> Diplonema -> Diakinesis?
The structure that forms during meiosis and facilitates the pairing of homologous chromosomes
What is synaptonemal complex?
Where does crossing over (in pachynema, P1) occur?
What is "@ the chiasmata"?
What is genetic recombination?
The process of making new eggs is called ___; and for making new sperm is called ___?
What is oogenesis; spermatogenesis?
