What type of microscope is best for studying DNA?
electron microscopes...According to my course in OK Virtual Highschool.."Hi-tech electron microscopes are used to study very small objects such as viruses. They can also be used to view the smallest of molecules that make up cells such as DNA in the nucleus. Unlike a compound microscope, an electron microscope can produce a three-dimensional image"
A typical human can clearly see an item as small as 0.5 mm across Which form of technology has enabled humans to see objects even smaller than this?
Microscopes, particularly electron microscopes, have enabled humans to see objects that are much smaller than 0.5 mm across. Electron microscopes use a beam of electrons to create high-resolution images of tiny structures, allowing researchers to visualize objects at the nanometer scale.
Why can't flagella be observed in action?
Flagella move very quickly, making it hard to observe their motion in real time under a typical light microscope. Additionally, the resolution of a light microscope may not be high enough to clearly visualize flagella in action due to their small size. Specialized techniques like high-speed video microscopy or electron microscopy are often used to study flagellar motion.
How much does a light microscope cost?
The cost of a light microscope can vary depending on the brand, features, and specifications. On average, a basic light microscope suitable for educational purposes can cost anywhere from $100 to $500, while high-end research-grade microscopes can range from $1000 to $10,000 or more.
How many times must bacteria be magnified in order to see them the naked eye?
They can't, at least not individually. You can grow a culture of them, though, and you can see large clumps of them; you won't be able to see the details of the bacteria, though. To actually see a bacterium, you need a microscope, and possibly even a scanning electron microscope.

What types of microscopes can be studied with an electron microscope?
objects smaller than 0.2 micrometers, or about one-fiftieth the diameter of a typical cell.
How thin must a specimen be in order to view it on a microscope slide?
A typical thickness for a specimen on a microscope slide is about 0.1mm to 0.2mm. However, for some specialized applications, thinner sections may be required, such as in electron microscopy where specimens can be as thin as 50-100 nanometers. The key is to have a thin enough sample to allow light to pass through for accurate viewing.
What is the typical cost of an atomic force microscope?
The typical cost of an atomic force microscope ranges from 20,000 to 500,000, depending on the model and specifications.
Can you see virus with the naked eye?
Since a virus is far smaller than a typical cell (much smaller than a prokaryote) a virus cannot be seen by a regular microscope. To see a virus, you should get an electron microscope.
What are typical transmission problems for Mazda 6i?
It has no typical transmission problems. They are very reliable.
Advantages of scanning elecctron microscope?
A Scanning Electron Microscope of SEM is a type of electron microscope that images a surface with high-energy electrons. These electrons interact with the atoms in the sample to produce signals that relate to the sample's surface topology and electrical composition. The main advantages of a SEM vs a typical light microscope - are the very large increase in overall resolution, generally hundreds of times great than what is possible with a light microscope. Also the exceptionally deep depth of field that allows one to display an almost 3 dimensional image, that allows one to study the surface structure of the sample.
What does prion look like?
Prions are infectious proteins that are misfolded and can self-replicate. They do not have a typical appearance as they are not living organisms but rather abnormal forms of normal cellular proteins. Under an electron microscope, prions may appear as protein aggregates or fibrils.
List the subatomic particles typical of a atom?
Proton, neutron, electron
Why is it important to take good care of your microscope?
for typical reasons top performance and good looks.
What are the typical applications of micro silica powder?
Typical applications include high-strength concrete, self-compacting concrete, precast concrete Silpozz products, shotcrete, and as an additive in cement and mortar formulations.
