kinetochore fibers
|
kinetochore fibers- extend from the kinetochore of each chromatids to centrosomes.
|
|
histones
|
histones- help maintain the shape of the chromosome and aid in the tight packaging of DNA.
|
|
prokaryotic DNA
|
prokaryotic DNA- circular DNA
|
|
tetrad formation
|
tetrad formation- Chromatids of the homologous chromosomes are aligned lengthwise so that the genes on one chromosomes are adjacent to the corresponding genes on the other chromosomes.
|
|
chromatin
|
chromatin- Less tightly coiled DBA-protein.
|
|
Haploid
|
Haploid- only contain one set of chromosomes
|
|
diploid
|
diploid- have both chromosomes for a homologous pair
|
|
autosome
|
autosome- non sex chromosomes
|
|
karyotype
|
karyotype- a photograph of the chromosomes.
|
|
synapsis
|
synapsis- the pairing of homologous chromosomes.
|
|
structure of a chromosome
|
structure of a chromosome- A chromosome is composed of two identical chromatids attached by a centromere. Each chromatid is made up of tightly wound DNA wrapped around histones. During cell division, spindle fibers attach to the kinetochore.
|
|
role, compoisition, shape of histones
|
role of histones- coiling- composed of-proteins shape-DNA, rod shape
|
|
Law of Independent Assortment: What it is, when it happens, what type of nuclear division.
|
type of nuclear division
random separation of homologous chromosomes metaphase 1 |
|
3 phases of Interphase and what's going on.
|
3 phases of Interphase and whatís going on.
G1 phase- offspring grow to a mature size S phase- cells DNA is copied G2 phase- cell prepares for cell division |
|
Spermatogenesis, Oogenisis: Differences in the final product.
|
Spermatogenesis, Oogenisis: Differences in the final product.
difference in products of spermatogenesis (4 viable sperm), oogenesis, (1 viable egg, 3 polar bodies, unequal division) |
