Genome

Genome

A genome is an organism’s complete set of genetic instructions. The genome of an organism is the whole of its hereditary information encoded in its DNA (or, for some viruses, RNA). It is an organism’s complete set of DNA, including all of its genes. This includes both the genes and the non-co.....

Microorganism

Microorganism

A microorganism or microbe is an organism that is microscopic, which means so small that people cannot see them with a naked eye. The major groups of microorganisms—namely bacteria, archaea, fungi, algae, protozoa, and viruses. These microorganisms have been often under-appreciated and under-st.....

Membrane Protein

Membrane Protein

A membrane protein is a protein molecule that is attached to or associated with the membrane of a cell or an organelle. They represent about a third of the proteins in living organisms. Examples of membrane proteins include ion channels, receptor proteins, and proteins that allow cells to connect.....

Anabolism

Anabolism

Anabolism is the set of metabolic pathways that build molecules from smaller units. It is the process by which the body utilizes the energy released by catabolism to synthesize complex molecules. Enzymes take little molecules and stick them together to make bigger molecules. Some of these enzymes.....

Lipid

Lipid

A lipid is a type of organic molecule found in living things. It is oily or waxy. Fats are made from lipid molecules. Sources of lipid can be found in algae, seeds, meat, cheese, butter, and fish. They are an important component of living cells. In the human body, these molecules can be synthesi.....

Ion Channels

Ion Channels

Ion channels are pore-forming proteins that help to establish and control the small voltage gradient across the plasma membrane of all living cells by allowing the flow of ions down their electrochemical gradient. They are present in the membranes that surround all biological cells. They are pres.....

Immunoglobulins

Immunoglobulins

Immunoglobulins are large Y-shaped proteins that can stick to the surface of bacteria and viruses. They are found in the blood or other body fluids of vertebrates. They act as a critical part of the immune response by specifically recognizing and binding to particular antigens, such as bacteria o.....
