Cell biology exam 1

What are cells constantly doing? Cell biology exam 1 focuses mainly on cellular structure and emphasizes optical techniques; Biochemistry: focuses on cellular structure and function; Genetics: focuses on information flow and heredity and includes sequencing of the entire genome all cell biology exam 1 the DNA in numerous organisms. Light microscopy. Light microscopy: earliest tool, cell biology exam 1, identifies nuclei, mitochondria, chloroplast, also called bright field microscopy because white light passes directly through a specimen, limit of resolution; Phase-contranst and DIC microscopy: make it possible to see living cells clearly, phase of transmitted light changes as it passes through a structure with different density from the surrounding medium, enhance and amplify slight changes; Fluorescence microscopy: allows detection of proteins, DNA sequences, or molecules that have been made fluorescent by binding to antibodies, antibody can be coupled to fluorescent molecule which emits fluorescence, GFP can be used to study temporal and spatial distribution of proteins; Confocal: use laser beam to illuminate single plane of fluorescently labeled specimen; Digital video: use video camera to collect digital images.

For this exam, you will need to know the properties of amino acids, nucleic acids, and phospholipids, as well as bonds, polarity, respiration, and photosynthesis. Browse Course Material Syllabus. Meet the Instructors. Meet the TAs. Types of Organisms, Cell Composition. Covalent Bonds, Hydrogen Bonds. Macromolecules: Lipids, Carbohydrates, Nucleic Acid.

Mendel's Laws. Download Course. Water has an indispensable role for life as it is the universal solvent in bio systems, its polarity is able to dissolve a large variety of substances. Hydrocarbons are chains or rings composed of only carbon and hydrogen; play a role in the structure of biological membranes; the interior of each bio membrane in non aqueous environment consisting of the long hydrocarbon tails of phospholipid molecules; the hydrocarbon tail project into the interior of the membrane form either surface. Cytology: focuses mainly on cellular structure and emphasizes optical techniques; Biochemistry: focuses on cellular structure and function; Genetics: focuses on information flow and heredity and includes sequencing of the entire genome all of the DNA in numerous organisms.

Linkage and Recombination, Genetic Maps. Chemiosmotic Principle, Photosynthesis. More Info. Make a table; proteins nucleic acids and polysaccharides, lipids share some features of macromolecules but are synthesized somewhat differently. Molecules of importantance to the cell biologist have a backbone or skeleton, or carbon atoms linked together covalently in chains or rings. Bacteria: prokaryotes nonnucleated, genetic info in nucleoid and present in cell as a chromosome, compartmentalize activities; Animal: eukaryotes, no cell wall but extracellular matrix, peroxisomes, vacuoles are temporary storage and transport, septins; Plants: eukaryotes, photosynthesis occurs, lots of chloroplast , plasmodesmata for communication and exhange.
