Pass UPDATE
what is gel made out of? - CORRECT ANSWER-agarose (which has massive
network of fibers that can have their density changed).
Meiosis - CORRECT ANSWER-division of the chromosomes in the gametogenic
cells (cells that produce gametes) of eukaryotes. Sexual reproduction--promotes
genetic variation
Reduction Division - CORRECT ANSWER-Aka meiosis--yields 4 daughter cells
that each have only half of the total genetic material to the parental cells, but are
not identical to each other or to the parental cell.
What's kind of nucleus does the cell have before and after meiosis? - CORRECT
ANSWER-diploid (starting) and haploid (end)
What happens to 1 diploid cell and 46 chromosomes after meiosis? - CORRECT
ANSWER-4 non-identical haploid cells and 23 chromosomes in each cell.
homologous chromosomes - CORRECT ANSWER-Non-identical chromosomes.
They have the same series of genes but they may have alternate "alleles" for these
genes.
, Sister Chromotids - CORRECT ANSWER-identical copy of each of the 46
chromosomes (referring to human chromosomes) except for any rare mutations
that pop up during the replication process since DNA polymerase is an enzyme,
which can make mistakes.
tetrad - CORRECT ANSWER-a structure that forms when two pairs of sister
chromatids in a homologous pair come together and intertwine. 2^23 possible
combinations before crossing over (very big!)
homologous recombination - CORRECT ANSWER-when the homologous
chromosomes swap arms.
Synapsis - CORRECT ANSWER-homologous chromosomes physically connect at
crossing points (chiasma).
Crossing over - CORRECT ANSWER-genetic recombination between maternal
and paternal homologous chromosomes
Meiosis happens to what organisms and except for? - CORRECT ANSWER-
meiosis applies to plants, animals, and fungi. Except bacteria
n is called - CORRECT ANSWER-haploid
2n - CORRECT ANSWER-diploid
