A. Alodine is a trade name for a brand of chromating solution used for MIL-C-5541 conversion coating of aluminum. Iridite is another trade name. The conversion coating can be done in clear, yellow, or yellow-and-leach (leach back to clear). Normally, the conversion coating is either for...
Through microscopic techniques, the concentration of chromosomes (in the nucleus or the nucleoids) causes parts of the cell to have a dense, dark appearance which represents the regions of the cell that contains DNA material. In organisms with several chromosomes (e.g. human beings have 23 pa...

callednucleosomes. A nucleosome is a histone-DNA complex. These were discovered when scientists used caustic materials to dissolve the outer proteins from chromosomes, leaving behind chromatin containing only histones and DNA. Chromatin offers a "beads on a string" appearance on microscopic examination...
around each histone octamer in the manner of thread wrapping around a spool approximately twice. Under a microscope, this gives chromatin a beady appearance, with "naked" DNA alternating with DNA enclosing histone cores. Each histone and the DNA around it makes up a structure called a nucleosome...
Prophase 1 is the longest phase of meiosis, during which three major events occur. The first part is the condensation of chromatin into chromosomes, the second is physical contact between homologous chromosomes, and the third is genetic information transfer between synapsed chromosomes. ...
Kv2.1 expression has also been shown to increase following damage, but before the appearance of apoptosis[208, 214]. Inhibi- tion of Kv2.1 has been shown to inhibit apoptosis in vitro[215], as well as in vivo[216]. Following cerebral ischemia, it was also found that Kv2.1 participates ...
Inside the nucleus is chromatin, the name for the form DNA takes when the cell is not preparing to divide: coiled, but not separated into chromosomes that appear distinct on microscopy. The nucleolus is the part of the nucleus containing recombinant DNA (rDNA), the DNA dedicated to the synth...
The French-American-British cooperative group, in their seminal paper of 1976, described a promonocyte as follows: 'This cell is similar to the monoblast but has a large nucleus with a cerebriform appearance; nucleoli may be present, but the cytoplasm is less basophilic, has a greyish ground...
