The result of a calibration may be recorded in a document, sometimes called a calibration certificate or a calibration report. See CLAS Requirements Document 6 Requirements for Calibration Certificates issued by CLAS Laboratories.
DNA and histone proteins are packaged into structures called chromosomes. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.Chromosomes are not visible in the cellâs nucleusânot even under a microscopeâwhen the cell is not dividing.However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope.n the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
The Visible Human Project is an effort to create a detailed data set of cross-sectional photographs of the human body, in order to facilitate anatomy visualization applications. A male and a female cadaver were cut into thin slices which were then photographed and digitized.
