As in other electron tomography techniques, the sample is tilted to different angles relative to the electron beam (typically every 2-3 degrees from about −60° to +60°), and an image is acquired at each angle. [5] This tilt-series of images can then be computationally reconstructed into a three-dimensional view of the object of interest. [6]
Microbiology (from Ancient Greek μῑκρος (mīkros) ' small ' βίος (bíos) ' life ' and -λογία () ' study of ') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).
The reference range for albumin concentrations in serum is approximately 35–50 g/L (3.5–5.0 g/dL). [5] It has a serum half-life of approximately 21 days. [6] It has a molecular mass of 66.5 kDa. The gene for albumin is located on chromosome 4 in locus 4q13.3 and mutations in this gene can result in anomalous proteins.
IV: Recombination is complete and the foreign DNA has integrated into the original bacterial cell's DNA and will continue to be a part of it when the bacterial cell replicates next. In microbiology , genetics , cell biology , and molecular biology , competence is the ability of a cell to alter its genetics by taking up extracellular DNA from ...
Human subject research is systematic, scientific investigation that can be either interventional (a "trial") or observational (no "test article") and involves human beings as research subjects, commonly known as test subjects. Human subject research can be either medical (clinical) research or non-medical (e.g., social science) research. [1]
Tertiary structure of human Cdk2, determined by X-ray crystallography. Like other protein kinases, Cdk2 is composed of two lobes: a smaller amino-terminal lobe (top) that is composed primarily of beta sheet and the PSTAIRE helix, and a large carboxy-terminal lobe (bottom) that is primarily made up of alpha helices.
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
X-ray photons create electron-hole pairs in a-Se, and the transit of these electrons and holes depends on the potential of the bias voltage charge. As the holes are replaced with electrons, the resultant charge pattern in the selenium layer is read out by a TFT array, active matrix array, electrometer probes or microplasma line addressing.
