DAILY DOUBLE Back

DAILY DOUBLE Back

This is the stage where chromosomes line up in the center of the cell metaphase Back

This is the stage where chromosomes are formed prophase Back

This is the longest phase of mitosis where the centrosomes are at opposite poles metaphase Back

this is the stage where the nucleolus disappears prophase Back

this is the phase where cohesin proteins are cleaved anaphase Back

This is the stage of meiosis where synapsis takes place Prophase I Back

This is the phase of meiosis where homologous chromosomes separate Anaphase I Back

This is the phase where sister chromatids are lined up in the center of the cell Metaphase II Back

This is the phase in meiosis I where half of the chromosomes are present when compared to prophase I Telophase I Back

This is the stage where microtubules attach to the centromeres of sister chromatids Metaphase II Back

Normal cell cycles are regulated by the presence of these Growth factors Back

Density-dependent inhibition This is the type of growth where cells can sense that there’s already enough cells surrounding it Density-dependent inhibition Back

These are the three checkpoints during the cell cycle G1, M, G2 Back

In order to surpass G2, you need these two proteins to come together to form this Cyclin + Cdk (cyclin-dependent kinase) = MPF (maturation promoting factor) Back

This is the property of many animal cells that must be attached to something before they can grow Anchorage dependence Back

somatic cells mitosis Back

interphase both Back

reduction division meiosis Back

Contains DNA both Back

Homologous chromosomes in metaphase meiosis Back

a structure of proteins associated with specific sections of chromosomal DNA at the centromere kinetochore Back

Radial array of short microtubules aster Back

Assembly of spindle microtubules centromeres Back

Shallow groove in the cell surface near the metaphase plate Cleavage furrow Back

Fibers made of microtubules and associated proteins Mitotic spindle Back

a cell containing half the chromosomes of another cell haploid Back

the “vehicles that transmit genes from one generation to the next” gametes Back

chromosomes that each carry genes controlling the same inherited characteristics homologous Back

the “physical manifestation of crossing over” chiasmata Back

proteins that keep chromatids together at anaphase I Shugoshi, cohesin Back

Individual chromosomes that carry genes derived from two different parents Recombinant chromosomes Back

this is the number of autosomal pairs of chromosomes in humans 22 Back

This is the stage in which chromosomes are extracted for a karyotype metaphase Back

This is the process of cancer developing and spreading metastasis Back

this is a nondividing stage that some cells such as nerve and muscles stay in Back
