Q

Centrosome

Study These Flashcards
A

an organelle near the nucleus of a cell that contains the centrioles (in animal cells) and from which the spindle fibers develop in cell division. Before the spindle apparatus forms, it’s orientation is determined which is accomplished by the centers out and organize them in the cytoplasm near the nucleus which consists of a pair of centrioles

21
Q

Centrioles

Study These Flashcards
A

Each one of the hollow tube porn by nine triplet microtubules a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.

22
Q

Three types of microtubules in the spindle

Study These Flashcards
A

Polar microtubules, Astral microtubules, Kinetochore microtubules

23
Q

Spindle

Study These Flashcards
A

spindle-shaped structure, composed of microtubules, that forms near the cell nucleus during mitosis or meiosis and, as it divides, draws the chromosomes to opposite poles of the cell.

24
Q

Chromatids

Study These Flashcards
A

Share a centromere

25
Chromosomes
Have their own centromere
26
Gametes
a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
27
Haploid
(of a cell or nucleus) having a single set of unpaired chromosomes.
28
Zygote
a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
29
Diploid
(of a cell or nucleus) containing two complete sets of chromosomes, one from each parent.
30
CDK
They catalyze the phosphorylation of target proteins that regulate the cell cycle. Protein that is always present but is active site is not cyclin binding change CDK exposing it's active site
31
Cyclin
A protein that is made only at a certain point in so cycle activate CDK
32
Three checkpoints during interphase and during mitosis
G1 checkpoint, S phase checkpoint, G2 checkpoint, and M checkpoint
33
Some functions at meiosis has evolved to serve
You reduce the chromosome number from diploid to haploid, to ensure that each of the haploid products as a complete set of chromosomes, to generate genetic diverse city among the products a.k.a. Gametes
34
Early prophase 1
The chromatic begins to condense following interphase
35
Mid prophase 1
Synapsis aligns homologous pairs, and chromosomes condense further
36
Late prophase/ prometaphase 1
The chromosomes continue to coil and shorten. The chiasmata reflect crossing over, the exchange of genetic material between nonsister chromatids in a homologous pair. In prometaphase the nuclear envelope breaks down
37
Metaphase 1
The HomoLogous pairs line up on the equatorial metaphase plate
38
Anaphase 1
The HomoLogus chromosomes move to opposite poles of the cell
39
Telophase 1
The chromosomes gather into nuclei in the original cell divides
40
Prophase 2
The chromosomes condense again following a brief interface in which DNA does not replicate
41
Metaphase 2
The centromeres of the paired chromatics line up across the equatorial plate of each cell
42
Anaphase 2
The chromatic and finally separate becoming chromosomes in their own right, and are pulled to opposite poles because of crossing over an independent assortment, each new cell will have a different genetic make up
43
Telophase 2
The chromosomes gather into nuclei, and the cell divides
44
Products of me meiosis
Divides into four cells each which has half as many chromosomes, all with different genetic make up
45
Cell death
Necrosis, apoptosis. Happens because the seller is no longer needed by the organism, the seller lives longer in this promo did you get a damage, incorrect nutrition death etc.
46
Translocation
During crossing over in meiosis is one chromatics from melodious chromosome pairs break and rejoin occasionally this can happen between non-melodious chromosomes and music quite common evening mitotic cells
47
Chiasmata
The X shaped attachment points
48
Crossing over
A chiasma is a point where genetic material is exchange between nonsister chromatids on homologous pairs, Crossing over results in recombinant chromatids and creates genetic variation.
49
Aneuploidy
The condition of having an abnormal number of chromosomes, having one extra chromosome is called a trisomy and missing one chromosome is called monosomy
