Mitosis Stages Meiosis Stages Mitosis, Meiosis or Both Growth Meiotic Anatomy Entropy…Yip pee!! Mitotic Anatomy

DAILY DOUBLE Back

DAILY DOUBLE Back

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

Back prophase This is the stage where chromosomes are formed

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

this is the stage where the nucleolus disappears Back prophase

this is the phase where cohesin proteins are cleaved Back anaphase

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

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

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

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

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

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

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

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

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

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

somatic cells Back mitosis

interphase Back both

reduction division Back meiosis

Contains DNA Back both

Homologous chromosomes in metaphase Back meiosis

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

Back aster Radial array of short microtubules

Back centromeres Assembly of spindle microtubules

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

Back Mitotic spindle Fibers made of microtubules and associated proteins

a cell containing half the chromosomes of another cell Back haploid

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

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

the “physical manifestation of crossing over” Back chiasmata

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

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

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

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

This is the process of cancer developing and spreading Back metastasis

this is a nondividing stage that some cells such as nerve and muscles stay in Back G0 stage
