solutions
cell division - ANSW-generate new cells identical to parent cells
genome - ANSW-the complete set of genetic information of an organism
Humans have how many chromosomes? - ANSW-46 (23 pairs)
homologous chromosomes - ANSW-Chromosomes that are "matching" and same genes at the same
position (locus) .... one copy each from parent
alleles - ANSW-different versions of a gene
diploid (2n) - ANSW-2 of each chromosome, one from each parent
somatic cells - ANSW-Any cells in the body other than reproductive cells also known as diploid cells
haploid (n or 1n) - ANSW-cells that have only one set of chromosomes
gametes - ANSW-reproductive cells (eggs and sperm) also known as haploid
Karyotype - ANSW-A picture of all the chromosomes in a cell arranged in pairs
lifecycle of a cell includes... - ANSW-interphase and miotic phase
Interphase - ANSW-Cell grows, performs its normal functions, and prepares for division; consists of G1, S,
and G2 phases
Miotic phase (PMAT) - ANSW-short period of time when cell divides; mitosis and cytokinesis
interphase: G1 - ANSW-cell builds proteins and energy
interphase: S phase - ANSW-DNA replication/duplication
interphase: G2 - ANSW-organelles duplicated and energy produced
Miotic Phase: Prophase - ANSW-cells chromatin condenses into compact sister chromatids
Miotic Phase: Metaphase - ANSW-cell's chromosomes line up at center of dividing cell
Miotic Phase: Anaphase - ANSW-sister chromatids separated
Miotic Phase - Telophase - ANSW-dividing cell's chromosomes completely separated
Cytokenisis (Mitosis) - ANSW-cytoplasm divides into 2 identical cells (overlaps at end of mitosis)
G1 checkpoint - ANSW-checks for cell size, nutrients, growth factors and DNA damage
G2 checkpoint - ANSW-checks for cell size and DNA replication
M checkpoint - ANSW-Spindle assembly checkpoint. Mitosis will not continue if chromosomes are not
properly aligned.
anchorage dependence AND density dependence - ANSW-of normal mammalian cells typically prevents
mitosis from occuring when it's not needed
anchorage dependence - ANSW-The requirement that a cell must be attached to a substratum in order
to initiate cell division.
density dependence - ANSW-cells will not divide if they don't have enough room
Cancer - ANSW-a group of cells exhibiting uncontrolled growth
