Study Notes
Cell Cycle and Mitosis
- Learning Target: Model and describe the cell cycle, including mitosis.
- Reproduction transfers genetic information to offspring.
- Multicellular organisms sometimes use asexual reproduction.
- Interphase, mitosis, and cytokinesis are key processes.
- DNA replication is crucial for cell division.
- Cancer is a result of uncontrolled cell growth.
- Key cell cycle phases include interphase (G1, S, G2), prophase, metaphase, anaphase, telophase, and cytokinesis.
- During these phases, DNA condenses, chromosomes separate, and the cell divides.
- Key terms include: interphase, G0, G1, S, G2, DNA replication, prophase, metaphase, anaphase, telophase, poles, equator, chromosomes, chromatids, centrioles, spindle fibers, parent cell, daughter cells, centromere, nuclear membrane, chromatin, cytokinesis, cell plate, cleavage furrow, cancer, asexual reproduction, centrosome, metaphase plate.
Meiosis
- Learning Target: Describe the stages of meiosis and compare them to mitosis.
- Meiosis creates different cells than mitosis.
- Meiosis is necessary for sexual reproduction.
- Diploid cells differ from haploid cells.
- Meiosis involves two rounds of cell division.
- Stages of meiosis (PMAT 1 and PMAT 2) unique from mitosis.
- Daughter cells after meiosis are genetically different from each other and from parent cells.
- Meiosis increases genetic diversity.
Virus Replication
- Learning Target: Compare viruses and bacteria in terms of genetic material and reproduction.
- Viruses replicate under specific conditions.
- Viruses transmit genetic material into a host cell.
- Bacteria contain genetic material (DNA).
- Lytic and lysogenic cycles are key stages in viral reproduction.
- Prokaryotes use processes like conjugation, budding, and binary fission for sexual and asexual reproduction.
- Binary fission is the most common form of reproduction in prokaryotes.
- Key terms include: meiosis, haploid, zygote, tetrad, interkinesis, sexual reproduction, gamete, somatic cell, diploid, germ cell, fertilization, homologous chromosome, genetic diversity, variation, lytic cycle, lysogenic cycle, phage, plasmid, conjugation, budding, binary fission.
