Answer:
Electron Microscope
Explanation:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.
Answer:
chromosomes
Explanation:
DNA of organisms is organized into one or more thread-like structures called chromosomes. Chromosomes are made of DNA and its packing proteins. During cell division, the thin mass of chromatin which in turn is made of DNA and its packing protein condense and becomes visible as individual chromosomes. The DNA molecule is wrapped around histone proteins to form nucleosomes which in turn become compact into chromatin fibers.
The further condensation of looped domains formed by the coiling of chromatin fiber forms chromosomes. The part of a chromosome that holds its two arms together is called centromere. Chromosome becomes visible during the prophase stage only when condensation of chromatin takes place.
