Phases of Mitosis
Chromatin condenses into chromatids and the nuclear envelope dissipates.
What is Prophase?
Must occur before Meiosis takes place -- normal cellular functions and DNA replication.
What is Interphase?
The number of chromosomes in the human genome.
What is 46?
Layered structure wherein mitosis and meiosis take place.
What is the Nuclear Envelope?
"Cell death".
What is apoptosis?
Chromosomes line up down the center of the nucleus.
What is Metaphase?
Crossing over occurs as well as attachment of microtubules to the kinetochore.
What is Prophase I?
The exchange of segments of DNA from paired chromosomes.
What is Recombination?
Region where sister chromatids attach to each other.
What is the Centromere?
When a cell fails to hit these, the process of cell division can go awry.
What are checkpoints?
Sister chromatids do this during Anaphase.
What is pulling apart towards polar sides of the nucleus?
The chromosomes line up in the middle of the cell by homologous pairs.
What is Metaphase I?
Yield of 1 diploid parent cell after going through meiosis.
What are 4 haploid daughter cells?
Uncondensed genetic information that resides in the nucleus during interphase.
What is Chromatin?
Disease caused by rapidly increased cell division process.
What is cancer?
Nuclear envelopes form around sister chromatids.
What is Telophase?
Action that occurs ONLY in Meiosis -- NOT in Mitosis.
What is homologous pairing?
Two chromosomes in a pair have the same length, centromere position, and genetic information.
What are homologous chromosome?
_____ is the process of cell division through phases, whereas _____ is the physical division process of 2 identical cells.
What is Mitosis; Cytokinesis.
The stage of Meiosis that is most similar to Mitosis.
What is Meiosis II?
DNA molecules of non-sister chromatids are broken and rejoined to each other.
What is Crossing Over?
