Study Notes
Microscopy in Cell Biology
- Microscopy is essential in modern cell biology, aiding in the observation of cellular structures and functions.
- Forms of microscopy include light, fluorescence, and electron microscopy, each offering unique insights into cellular components.
Electron Microscopes
- Invented in the 1930s, electron microscopes utilize beams of electrons for illumination, allowing for higher resolution imaging than light microscopes.
- This technology makes it possible to visualize individual larger molecules that are otherwise undetectable.
Transmission Electron Microscopy (TEM)
- TEM is a type of electron microscopy providing detailed images of thin specimens by transmitting electrons through the sample.
- Micrographs produced by TEM can show intricate details of small regions within a cell, enhancing understanding of cellular architecture.
- DNA can be stained for visualization; specific stains (e.g., green) highlight DNA, demonstrating the technique's effectiveness in molecular observation.
