Kohlberg’s six-stage theory was an extension of Jean Piaget’s cognitive development theory (how people learn and use knowledge is affected by both social and psychological factors). Kohlberg extended on Piaget’s theory, proposing that moral development is a continual process that occurs throughout the lifespan (the stage you are in life determines your level of moral…
Erikson’s theories are the best-known theories of personality and development. Erikson believed that personality develops in a series of predetermined stages. His theories are psychosocial, and not psychosexual. Describes the impact of social experience across the whole lifespan. In each stage of development, Erikson described conflicts that act as turning points in life. In Erikson’s…
Enzymes are biological catalysts, responsible for directing the flow of chemical reactions that is the basis for life. By far the majority of enzymes are proteins, but some consist of RNA or a complex of protein and RNA. Enzymes are remarkably specific, acting on only one or a few types of molecules (called “substrates” of…
As mentioned, the range of protein functions is enormous: from passive structural elements to active motor proteins and everything in between. What characteristics of proteins are required for them to carry out these functions? While these characteristics vary from protein to protein, there are some that can be found in most proteins. We will discuss…
It is often necessary to obtain a preparation containing protein molecules of only a single type (a “pure protein”); eg. for medical use or scientific study. With such preparations, one may determine 3D structure, binding affinities, or determine the amino acid sequence. Obtaining a pure protein is generally challenging because there are thousands of proteins…
Proteins are the largest and most varied class of biological molecules, and they show the greatest variety of structures. Many have intricate three-dimensional folding patterns that result in a compact form, but others do not fold up at all (“natively unstructured proteins”) and exist in random conformations. The function of proteins depends on their structure,…
More properly known as alpha-amino acids, their general structure is: Nineteen of the twenty amino acids have the same arrangement around the central alpha-carbon: a. an amino group, b. a carboxyl group, c. a hydrogen, and d. an R group (called the “side chain”) which differs for each amino acid. Recall that when 4 different…
The term “dogma” describes a doctrine or code of beliefs accepted as authoritative. The central dogma of biology refers to the way that genetic information is stored and retrieved in living cells. The classic relationship is DNA > RNA > Protein. Thus DNA functions as the information storage molecule, and this information is “read out”…
