• Unit 7: Cellular Reproduction: Mitosis

    Organisms require their cells to divide for the purposes of reproduction, growth, development, or repair. Cellular division is divided into two phases: mitosis and cytokinesis. Mitosis involves the division of the nuclear chromosomes, while cytokinesis is the division of the cytoplasmic components into new daughter cells. Serious consequences, such as cancer, can occur if this cell cycle is disrupted in some way.

    Completing this unit should take you approximately 6 hours.

    • 7.1: DNA and RNA

      Molecular biology is the study of subcellular structures, their interactions, and how they function in the biological processes of the cell. In particular, nucleic acids are important molecules that carry information that leads to the production of proteins. Proteins are the physical expression of genetic information in cells.

      The nucleic acids deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are important molecules that carry genetic information throughout cells. Like an architect’s blueprint, nucleic acids have a set of rules that lead to the synthesis of the major building blocks of living things.

    • 7.2: Cell Division

      All living things are made up of cells. All cells come from other cells through the process of cell division. Some cells divide for reproduction purposes, while others divide for growth, development, or repair.
