question		réponse
nondisjunction commencer à apprendre		results in a new cell having too many or not enough chromosomes
What is the purpose of sexual reproduction? commencer à apprendre		genetic variation
What results in genetic variation? commencer à apprendre		meiosis
what does crossing over produce? commencer à apprendre		genetic variation by producing new combination of alleles (genes)
Meiosis produces...? commencer à apprendre		4 haploid cells
Mitosis produces...? commencer à apprendre		2 diploid cells
What must occur before a cell can divide? commencer à apprendre		DNA replication
What divides the cytoplasm? commencer à apprendre		cytokinesis
What is mitosis responsible for? commencer à apprendre		growth and development
what role does the centromere play in cellular reproduction? commencer à apprendre		it is the area of attachment for chromatids
Which part of the cell cycle is when new cells are formed? commencer à apprendre		mitosis
What is the end result of asexual reproduction? commencer à apprendre		2 cells
What is the longest phase of the cell cycle? commencer à apprendre		interphase
What results when cell division happens at a high rate? commencer à apprendre		cancer
What is the correct order for cellular division commencer à apprendre		Prophase, Metaphase, Anaphase, Telophase
G1, S, and G2 phase are a part of? commencer à apprendre		interphase
Cytokinesis (def) commencer à apprendre		the last stage, the cytoplasm splits into half forming into two cells
interphase commencer à apprendre		consists of G1->S1->G2 phases
metaphase commencer à apprendre		chromosomes line up in the center of the cell and spindle fibers attach to chromosomes from centrioles
S phase commencer à apprendre		DNA and chromosomes are copied
telophase commencer à apprendre		chromosomes unravel into chromatin to provide DNA for new cell
prophase commencer à apprendre		chromosomes condense and nucleus and centrioles move to opposite poles
anaphase commencer à apprendre		chromosomes are pulled apart and sister chromatids are separated
G1 commencer à apprendre		the cell grows rapidly and replicates
G2 commencer à apprendre		replicates the rest of the organelles
cell cycle commencer à apprendre		the never-ending process by which all cells in your body replicate
haploid commencer à apprendre		half the number of chromosomes
diploid commencer à apprendre		the full set of chromosomes
gamete commencer à apprendre		reproductive cells
zygote commencer à apprendre		a diploid, when two gametes unite together in fertilization
mitosis commencer à apprendre		how eukaryotes replicate and divide; major part of the cell cycle
meiosis commencer à apprendre		asexual reproduction, a process that reduces the number of chromosomes by half
fertilization commencer à apprendre		when two gametes unite together to form a zygote
asexual reproduction commencer à apprendre		one parent cell splits into two daughter cells that are identical to the parent cell
sexual reproduction commencer à apprendre		two parents make one or more offspring that are genetically different than the parents
