Controls the function of the regulator genes. Two types: Operon, which causes function and Reperson, which ceases function.
Nuclear membrane disappears and chromosomes appear. Chromosomes divide and produce sister chromatids. Spindle fibers form.
Cytokinesis is completed. A new nucleus forms around the chromosomes and spindle fibers disappear. Plant cells form cell wall.
Differences between Animal and Plant Mitosis
~Centrioles not in plant cells
~Cell wall in plant cells, pinching of cytoplasm in animal cell ~Splitting of cell wall in plant cell
Differences between Mitosis and Meiosis
Mitosis: used for asexual reproduction/starts with diploid, ends with diploid.
Meiosis: used for sexual reproduction/starts with diploid, ends with haploid
Stages in Meiosis
Meiosis 1: Interphase, Prophase, Metaphase, Anaphase, Telophase
Meiosis 2: Prophase 2, Metaphase 2, Anaphase 2, Telophase 2
Diploid parent cell divides into two haploid daughter cells,but the new daughter cells are not identical to the parent cell
A. Each daughter cell produced in Meiosis 1 undergoes mitotic division.Each cell will produce two daughter cells each with a haploid number of chromosomes.
Sickle Cell Anemia
a genetic disorder that causes abnormal hemoglobin, resulting in some red blood cells assuming an abnormal sickle shape. Symptoms: Pain in joints, pain in abdomen, possible convulsion, and damage to liver, heart, or spleen.
