DNA Packing
the two strands of DNA
What is DNA double helix?
Order of the phases
phase where DNA undergoes synapsis
Extra Point: What is a bivalent?
What is Prophase I?
meiosis creates these, which allow organisms to sexual reproduce
What are gametes?
DNA double helix coiled around a protein
Extra Point: What is that protein called?
What is nucleosome?
Extra Point: histone
microtubules attach to the chromosomes
What is prometaphase?
how we define the chromosome after crossing over has occurred
What are recombinant chromatids?
what we are left with at the end of Meiosis II
What are four haploid cells?
nucleosomes coiled into a more condensed form
What is chromatin?
sister chromatids separate and travel to opposite poles
Extra point: What are the sister chromatids considered when they split?
What is Anaphase?
Extra Point: Chromosomes
this is what separates during Anaphase I
What are homologous chromosomes?
the name of an egg cell
Extra Point: What are the remaining cells called?
What is an oocyte?
Extra Point: polar bodies
the point of interaction or the region that holds sister chromatids together
What is centromere?
chromosomes are seen lined up in a row at the center of the cell
What is metaphase?
the point where homologous chromosome "legs" cross
What is a chiasma?
the incorrect number of chromosomes
aneuploidy
'one half' of a duplicated chromosome
What are sister chromatids?
When the cell plate forms to finish dividing the cells
What is cytokinesis in a plant cell?
the reason we cross over (many answers but think about the reason everyone looks different)
What is genetic variation?
when there is an incorrect number or an error in number of chromosomes after meiosis
What is nondisjunction?
