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"
What type of microscope would be best to use if you wanted to look at the parts inside of a cell?
you could use any regular microscope that has magnification up to 400 but the best type of microscope to use would be an electron microscope if you could afford one
What type of microscope would be best to view moldy bread?
Update to last answer by "bugs": We would use a light microscope. Bread does have electrons (all matter has electrons), however the fungal growths that cause mould are an appropriate size to be seen under the light microscope. We only use electron microscopy when the item is too small to be seen under a light microscope. For example, if we wanted to see the mitochondria of a cell, we could not see it under a light microscope as it is too small to practically zoom into, so we use electron microscopy as it gives us a better resolution image. Electron microscopy has nothing to do with the electron content of the sample. It is in the operation of the device. The device scans the sample with an electron beam. The electron content of the sample doesn't matter, although all matter does have electrons (unlike as stated in the above answer). // Lab Demonstrator Initial answer: i think it would be a flourescence microscope because it doesnt have electrons or sumthin like that. i honestly am not sure. but heres MY answer. --bugs.//
What criteria could you use to determine whether an unknown type of cell is from a plant or an animal?
If the cell is large enough, use a light microscope to analyze it. If it is too small, use an electron microscope. Identify the organelles within the cell. If there are chloroplasts, a central vacuole, or a cell wall, it is a plant cell.
What are the significant of microscope?
Microscope is an instrument that helps to view minute items and the study of small items is microscopy. There are different types - namely - light, compound, phase contrast, transmission electron microscope, scanning electronmicroscope etc.The uses of microscope includeVisualization of microorganism and other micro level objects.Characterize the organism that cause the diseaseIdentify the type of toxin molecule produced.Obseve the cells and atoms so as to observe and corelateany variation in the shape, structure and functionLeeuwenhoek waq a Dutch naturalist who invented the microscope. Until then, there was not understanding of bacteria or the human body. Now they could be examined by the microscope. Leeuwenhoek studied bacteria, sperm, muscle striation, blood cells, etc. Now it continues to be used to study all kinds of physiological substances, is used to diagnose diseases, determine cell structure, many uses for determining illness and normallcy. It is used in forensics to help either convict or set free a person charged with a crime. It is used by botanists to study plants. Every scientist uses the microscope.
What is a non-optical microscope that magnifies up to 250000?
A transmission electron microscope could do this magnification.
Why was the first microscope invented?
the microscope was originally invented so that scientist could get a better look at cells
What type of microscope could be used to study a virus?
Its an electron microscope.It might be scanning electron microscope or TEM
What is the maximum power magnification of the microscope?
Actual magnification of light microscopes could reach up 1000x magnification depending on the type of light microscope. Light microscopes could be divided into brightfield microscope and phase-contrast microscope for viewing stained specimen and unstained specimen respectively. Magnification of electron microscope on the other hand could go up to 1000000x. The actual magnification as well depends on types of electron microscope which includes transmission-electron microscope and scanning-electron microscope where both of them are used in viewing internal cell structures and cell surface structures respectively.

What could produce an image of individual atoms?
scanning electron microscope
Would you use a stereomicroscope or compound light microscope or electron microscope to see a virus?
A virus of 50nm would be too small to see unless an electron microscope was used because it has greater resolving power and a resolution up to .1nm. A microscope using compound light as the means of illumination could not resolve better than approx. 200nms.
Why did the microscope have to be invented before cells could be discovered?
Because if the microscope wasn't invented we would have no clue that cells existed.
Even when it was light outside could cole cushing see his penis anyways?
No, it was so incredibly small that he couldn't see it until the electron microscope ws invented in 1933.
What are the tools that scientists used to observe atoms?
They could use an electron microscope or an STM (scanning tunneling microscope)
What powerful microscope is used in college?
You're probably thinking of the scanning electron microscope. But it could be anything. Your question is not specific enough.
Which microscope should be ued for a virus is 50nm in size and why?
A virus of 50nm would be too small to see unless an electron microscope was used because it has greater resolving power and a resolution up to .1nm. A microscope using compound light as the means of illumination could not resolve better than approx. 200nms.
