Cells can vary between 1 micrometer (μm) and hundreds of micrometers in diameter. Within a cell, a DNA double helix is approximately 10 nanometers (nm) wide, whereas the cellular organelle called a nucleus that encloses this DNA can be approximately 1000 times bigger (about 10 μm). Se...
Some merozoites grow into large cells, each with a large nucleus in a dense cytoplasm filled with amylopectin granules, the macrogametes. In the suborder Eimeriina, to which most of the coccidia infecting molluscs and crustacea belong, other merozoites from the last merogony enter host cells and...
the solution containing the bacterial cells being circulated from the cell separator to the fermenter by a circulating device to perform amino acid fermentation continuously, and bubbles being removed from the fermentation solution by a bubble separator before the fermentation solution is fed to the cir...
根据第一段的Researchers at the University of Massachusetts Amherst (UMass Amherst) recently announced that they have figured out how to engineer a biofilm that harvests the energy in evaporation (蒸发) and changes it to electricity(马萨诸塞大学阿姆赫斯特分校的研究人员最近宣布,他们已经...
However, the FMR spectra of magnetic crystals isolated from magnetotactic cocci were very similar to the FMR spectra of whole cells, because the chain arrangement was maintained due to the large size and prismatic shape of the crystals. Our data support the use of FMR spectra to detect ...
There are a variety of cells involved in immune responses, each responsible for their own duties. However, these cells must work together for a comprehensive response. Answer and Explanation: Antigen presenting cells engulf a pathogen...
1 Note that although there is light nonspecific staining of the nucleus within the control sections (B, D, and F) this is in marked contrast to the strong cell surface staining in sections stained with the specific reagents. Similar results were obtained using transfected CHO-K1 cells and via...

Describe the uses of DNA ligase in cells. The amount of DNA per nucleus was measured on several hundred cells from within the tip of an onion root. The amount ranged from 5 to 10 picograms. A cell with 5 picograms of DNA is probably in which of the following stages of the...
Bacteria are simple, single-celled organisms and are the most abundant type of life on Earth. A typical bacterial cell consists of a cell envelope, internal structures and external appendages. Unlike mammals and other eukaryotes, bacteria do not possess a nucleus; instead, the chromosomal DNA is...
