Study Notes
Cell Cycle and Division
- Cells with one copy of the genome are called haploid cells.
- Cells with two copies of the genome are called diploid cells.
- Apoptosis is the process of cell death that is a normal part of growth and development.
Cell Cycle Phases
- The sequence of activities as a cell prepares for and undergoes division is called the cell cycle.
- DNA replication occurs during the S phase of the cell cycle.
- The G2 phase occurs after DNA replication but before mitosis begins.
Cell Structure and Division
- The centriole is the structure that organizes microtubules into the mitotic spindle.
- The spindle fibers are composed of microtubules that pull sets of chromosomes apart in a dividing cell.
- The centromere is the largest constriction in a chromosome, located at a specific site in each chromosome.
Mitosis and Cytokinesis
- The division of a cell nucleus during mitosis is called karyokinesis.
- Mitosis is the process that produces two new cells that are both genetically identical to the original cell.
- Cytokinesis is the process that produces two new cells that are both genetically identical to the original cell.
Cellular Components
- Chromatin is composed of strands of chromosomal material in replicated chromosomes.
- Protein synthesis, lipids, and carbohydrates contribute to building the extra plasma membrane required to surround the two new cells that form from the original one.
Specialized Cells
- Stem cells are cells that divide to give rise to differentiated cells.
- There are multiple specialized types of cells mentioned in the text, but the exact number is not specified.
