Methods Used to Define Protein Structure

There are different levels and types of methods and applications used to determine protein structure and protein sequence. Proteins are found in all living organisms. They thus represent one of the most important classifications of biologically active molecules. Proteins are derived from carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus atoms. There are a number of […]

A plethora of factors may be responsible for problems but there is increasing evidence of genetic causes for a number of conditions. Species or races with relatively small populations are known to be particularly prone to genetic problems. […]

Biologists uncover regulatory mechanism for gene expression in the visual system

 Biologists have uncovered a key regulatory mechanism used for gene expression in the visual system. Their findings, which appear in the latest issue of the journal Cell, offer new insights into the complexity behind the genetic make-up of biological systems. The study, which included researchers from New York University’s Department of Biology, Japan’s Okayama University, […]

Important Roles of Genetics and the Limbic System in Aggressive Behaviors There have been several studies that clearly demonstrate the role of genetics and the limbic system in aggression. Although the subject of aggression can be quite complex in human beings, this information will hopefully shed light on the limbic system genetics aggression relationship.Defining Aggression. […]

Understanding the Genetics of Achondroplastic Dwarfism

Genetics of Achondroplastic Dwarfism In learning about the genetics of achondroplastic dwarfism we know that it is a very common type of dwarfism. This bone growth disorder is characterized by cartilage having trouble turning into bone. This is especially true for the long bones in the patients legs and arms. As the most common short-limbed […]
