    Study Notes

    Cell Biology Basics

    • The primary role of the smallest unit of life, the cell, is to maintain homeostasis and sustain life.
    • The main function of the plasma membrane in a cell is to separate the internal environment from the external environment.

    Tools of the Cell Biologist

    • A modern cell biologist's toolkit for understanding cells includes various components.

    Focus of Molecular Biology

    • The study of molecular biology focuses on the molecular structure and function of cells.

    Scope of Cell Biology

    • The study of cell biology encompasses the structure, function, and behavior of cells.

    Defining Characteristics of Cells

    • The inside of the cell is distinguished from the nonliving world by the presence of organelles and biomolecules.

    DNA Replication

    • The enzyme responsible for making faithful copies of the DNA code is DNA polymerase.

    Energy Currency

    • The molecule that serves as the common energy 'currency' in many living cells is ATP (adenosine triphosphate).

    Protein Synthesis

    • Ribosomes are responsible for reading mRNA into protein.

    Gene Expression

    • The process that permits a choice to express or repress a gene by converting the DNA code into RNA is transcription.

    Endergonic Reactions

    • Endergonic reactions are involved in anabolic reactions.

    Storage of Genetic Information

    • The molecule that stores the code of life is DNA (deoxyribonucleic acid).

    Information Transfer

    • mRNA, tRNA, and rRNA are intermediates of information transfer.

    Exergonic Reactions

    • Exergonic reactions are reactions that liberate energy and increase disorder.

    Medical Applications

    • Understanding cell biology allows for the development of treatments for diseases such as cancer, diabetes, infectious diseases, and cystic fibrosis.
