Hereditary versus somatic DNA mutations
By: Tami Port MS
There are two main categories of mutation based on the type of cell that the genetic change occurs in. These alterations to a person's DNA can be inherited or acquired after fertilization. Here is a summary of the difference between hereditary and somatic DNA mutations...
What is mitochondrial DNA (mtDNA)?
By: Tami Port MS
Mitochondria are the cellular organelles that manufacture most of the energy that our cells need to function. Cellular respiration, series of reactions that take place within the mitochondria, complete the process of turning food energy into ATP energy that can be used in many different...

Amino acids are fundamental building blocks for proteins. Proteins are made of long chains of amino acids. Sometimes these chains can be thousands of amino acids long. They twist and turn, with different parts of the amino acids interacting with each other, ultimately forming the...
What are starches?
By: Damilola Owoyele
Starch is an age-old substance that can be traced down the history line. Romans use it to augment their looks as a cosmetic; Egyptians being more technical used it as paste to stiffen weaved clothes and as adhesive; Chinese were literal about its use to...
What are fatty acids?
By: Brittany Welch
Fatty acids may sound harmful and toxic to the human body but in all reality they are actually required to maintain healthy levels of liquid in blood. Fatty acids are produced when fats from food are broken down. Fatty acids can be found in the...

Proteins make up over 50% of the dry weight of any given living cell and are critical for many important biological processes and systems, including maintaining structure, catalyzing reactions and cell signaling. The basic subunit, or "building block", is the amino acid. These small, varied...
What is the Human Genome Project?
By: Wendy R.
The Human Genome Project was a project undertaken in 1990 by the U.S. Department of Energy and the National Institute of Health. This project was expected to take fifteen years to complete, but because of rapid advances in technology, was completed a few...
What are fatty acids?
By: Louis Rosenfeld
Fatty acids are unbranched hydrocarbons (carbon chains with hydrogens attached) with an organic carboxylic acid group at the end. The carbon chains in some hydrocarbons can be branched, but naturally occurring fatty acids are not branched. The carboxylic acid group consists of a carbon double-bonded...
What are complex carbohydrates?
By: Gwen Powell
Carbohydrates get their name from the elements that compose their molecular structure, namely carbon, hydrogen and oxygen. Complex carbohydrates generally consist of long chains of glucose molecules, unlike simple carbohydrates (commonly referred to as sugars) which are formed from only one or two sugar molecules...

We are of the species "Homo Sapiens". Our genome refers to all of the genes that our species possesses. The genome can be likened to a "blueprint" of our physical structure. The genome contains all of the genes, or the data needed, to build a...
