cellular division Flashcards
(14 cards)
necrosis
unnatural cell death
apoptosis
programmed cell death
nondisjunction
failure of chromosome separation during cell division
crossing over
the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring
gamete
a mature sexual reproductive cell, as a sperm or egg, that unites with another cell to form a new organism.
haploid
n - 23 chromosome
diploid
2n - 46
sexual reproduction
two parents contribute genetic information to produce unique offspring.
asexual reproduction
generates offspring that are genetically identical to a single parent.
cytokinesis
pinching off creating 2 new daughter cells
mitosis
Prophase Prometaphase metaphase anaphase telophase
meiosis
Meiosis I and II
interphase
G1 Phase - cell growth
S Phase - dna replication
G2 phase - preparation fot mitosis
G0 Phase
cell division stops
