Isolation of polypeptide sample & measurement of its concentration

From: The American Biology Teacher | Date: February 1, 2000| Author: | Copyright information

Cells are the basic units of life. An organism can be composed of a single cell, such as members of the kingdoms Monera, Protista and Fungi; or many cells, such as members of the kingdoms Fungi, Plantae and Animalia. A great body of exciting research during the past 50 years has demonstrated that a "flow of information pathway" exists in all cell types studied thus far: DNA is transcribed into RNA and RNA is translated into polypeptides or proteins. As a point of clarification, it is necessary to point out that the term polypeptide refers to a discrete linear sequence of amino acids while the ...
