Cell biology exam 1

What are cells constantly doing? 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. 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 cell biology exam 1 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.

Find Flashcards. Brainscape helps you realize your greatest personal and professional ambitions through strong habits and hyper-efficient studying. More Info. Hydrophobic: tendency of nonpolar groups within a macromolecule to associate with each other to minimize their contact with water water fearing; Hydrophillic: water loving; solute: substance that is dissolved in solvent; Solvent: fluid in which another substance can dissolve. Academy Contact Find Us. Proud member of:. Make a table; proteins nucleic acids and polysaccharides, lipids share some features of macromolecules but are synthesized somewhat differently. Chemiosmotic Principle, Photosynthesis. Carbon atoms usually form covalent bonds with other carbon atoms and with oxygen, hydrogen, nitrogen, and sulfur. One condition is varied- independent variable, all other variables are kept constant, the outcome is dependent variable; in vivo- involve living organisms; In vitro- done outside of living organisms; In-silico- done in computers. 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. Exam 2. Freely sharing knowledge with learners and educators around the world.

Recombinant DNA. Electron microscope: use beam of electrons rather than light, limit of resolution about times better than light microscope, magnification is much higher up to ,x; Transmission electron: electrons transmitted though the specimen; Scanning electron: surface of specimen is scanned by detecting electrons deflected from outer surface; All this allowed for visualization of specimen in 3-D and allows visualization of individual atoms. Download Course. What are cells constantly doing? Departments Biology. Electron Microscopy. Molecules of importantance to the cell biologist have a backbone or skeleton, or carbon atoms linked together covalently in chains or rings. Terms and Conditions. Exam 3. 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.
