Virus

A virus is a small infectious agent that can replicate only inside the living cells of organisms. Most viruses are too small to be seen directly with a light microscope. Viruses infect all types of organisms, from animals and plants to bacteria and Archaea.


Although there are millions of different types. Viruses are found in almost every ecosystem on Earth and are the most abundant type of biological entity. The study of viruses is known as virology, a sub-speciality of microbiology.

Bacteria

What is Bacteria? Bacteria are a large group of prokaryotic organisms, except Archaea. Bacteria have a very small size (microscopic) and have a big role in life on earth. In the classification bacteria classified in the Divisio schizomycetes.

Several groups of bacteria known as causative infection and disease. While other groups could provide enormous benefits to human life, particularly in food, medicine, and industry.

Cell

What are Cells? Cells are the smallest organizational unit that became the basis of life. All functions of life are organized and take place inside the cell. Therefore, the cell can function as autonomous as long as all their needs are met. All cellular organisms are divided into two groups, namely organisms prokaryotes and eukaryotes organisms.

RNA

What is RNA? Ribonucleic Acid (RNA) is a chain of nucleotides present in the cells of all life. RNA has a number of important functions for living organisms, ranging from the regulation of gene expression to assistance with copying genes. Severo Ochoa, Robert Holley, and Carl Woese all played critical roles in discovering RNA and understanding how it worked, and more research on RNA is constantly being performed.

Many people are familiar with deoxyribonucleic acid (DNA), a nucleic acid which is often referred to as the “building blocks of life” because it contains the genetic material for its parent organism. RNA is equally important, even if it is lesser known, because RNA plays a critical role in helping DNA to copy and express genes, and to transport genetic material around in the cell. RNA also has a number of independent functions which are no less important.

DNA

DNA was first purified in 1868 by Swiss scientist Friedrich Miescher in Tubingen,Germany, who named it Nuclein based on its location within the cell nucleus. However, research on the role of DNA in the new cells began in the early 20th century, along with the discovery of Mendelian genetics postulates. DNA and protein molecules that are considered the two most likely as a carrier of a genetic trait based on the theory.

What is Gene

What is Gene? Genes are the units of heredity of living organisms. Physical form is a DNA sequence that becomes the password of a protein, polypeptide, or a strand of RNA that has a function to organisms that possess it.

Genes inherited by an individual to the offspring through a process of reproduction, together with DNA that carries it. Thus, information that maintains the integrity of form and function of an organism's life can be maintained.
