Prokaryotes are evolutionarily ancient, for billions of years the only form of life. Here's a summary of the basic "parts & pieces" of these primitive cells.

Prokaryotic cells can have a variety of surface appendages - flagellum, fimbria or pilus - that enable them to move, adhere to surfaces and even infect host cells.

Many science students are looking for short-cuts to make learning cell biology effortless. There are none, but there are strategies to help compare the two cell types.

There is an ordered regularity to the pandemonium of life on Earth.

All organisms are made up of cells. There are single-celled and multi-celled organisms. Here is a brief overview of what a cell consists of, and some of its functions.

Genetics is concerned with how traits are passed on through generations. This information, genetic material, is stored inside cells, working units that make up organisms.

In this simple classroom experiment students take oral swab samples to see if the use of mouthwash reduces the number and variety of oral bacteria found in the mouth.

Some bacteria have an additional layer outside of the cell wall called the glycocalyx. This coating of macromolecules protects the cell and helps it adhere to surfaces.

See the structure, nature and function of ribosomes - cell organelles essential for life. Ribosomes work with messenger RNA to manufacture all necessary cell proteins.

A look at the structural components of eukaryotic and prokaryotic cells and the differences between the two types of cell.

Animals and plants are eukaryotes, composed of cells that have a nucleus, and membrane-bound organelles. But animal cells have a few different features than plant cells.

Although bacterial reproduction results in the generation of clones, prokaryotes can undergo genetic recombination through transformation, transduction, and conjugation.

The eukaryotic cells of plants and animals possess several critical differences from prokaryotic cells, including a nucleus and other membrane-bound organelles.

Whether you know it or not, eukaryotic cells are the tiny units of life that make up your entire body. Read on and learn more about yourself!

Both plant and animal cells are eukaryotic, with many similarities, but there are also key differences between the cells of plants and animals. Here is a summary.

The amount and location of peptidoglycan in the prokaryotic cell wall is what determines whether a bacterium is Gram-positive or Gram-negative.

Bacteriophages are a special type of virus that exclusively infects bacterial cells. Here's how they recognize, take over and ultimately kill their host bacteria.

Cells that are small and primitive, or large and more complex, are organized to promote their sustenance and survival. Even the simplest of cells are very complex.

All living things are composed of one or more cells. Unlike cells, viruses, viroids and prions are acellular, nonliving parasites that require a living host to reproduce.

Infectious disease can result of cellular organisms, such as bacteria (prokaryotes), from eukaryotes (cells like ours) or from nonliving infectious agents.

Studying cell biology doesn't have to suck. Here's a fun and fascinating summary of how the cells of your body work to keep you alive and healthy.

Most bacteria have one of these two types of cell walls. The differential Gram stain uses two dyes to distinguish between bacteria based on cell wall structure.

Antibiotics are drugs used to fight bacterial infections. How do these medications work to kill bacteria without harming human cells?

Bacteriophages reproduce by commandeering a bacterium and ultimately killing it. But sometimes, through lysogeny, the phage doesn't immediately take over its host.

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do sulfonamides impact bacteria without hurting our cells?

The distinction between species of sexually reproducing organisms is quite clear, but how are the lines drawn for organisms, like bacteria, that reproduce as clones?

With recent news about three parent zygotes created to replace defective maternal mitochondrial DNA, you might be wondering "What is a mitochondrion?"

Archaea are prokaryotes that differ from bacteria and eukaryotes enough to be assigned to their own taxonomic domain. Here is a brief introduction to Archaeans.

Classical genetics is the oldest field within genetic science, and an essential foundation for several other disciplines.

The cell's endomembrane system consists of the rough and smooth ER, Golgi apparatus, vesicles and plasma membrane, all working together to transport cellular materials.

Bacteria and viruses are both tiny infectious agents with the ability to cause disease. So it is not surprising that these microbes are sometimes mistaken as the same.

This series of articles explores how viruses that exclusively infect bacterial cells recognize the hosts they parasitize and reproduce once the bacterium is infected.

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do quinolones destroy bacteria without hurting our cells?

Antibiotics are chemotherapeutic agents used to inhibit or kill bacteria (prokaryotic organisms). How do tetracyclines destroy bacteria without hurting our cells?

What are deoxyribonucleic and ribonucleic acid made of, and how are these big molecules of genetic information built? This article explains the basics.

The mechanisms of inhibition of bacterial protein synthesis become clearer each year. The recent Nobel Prize in Chemistry rewarded the clearer understanding of ribosomes.

Some living things reproduce by cloning; producing offspring that are genetically identical to the parent. Organisms that procreate sexually create genetic novelty.

After completing a classroom experiment in which students take oral samples to see if mouthwash reduces the number and variety of bacteria, this is how data are examined.

Some of the early discoveries that led to today's vaccines happened almost by chance. The astute observations of Jenner and Pasteur were the foundation of immunology.

Scientific classification sorts all life forms on Earth into five kingdoms: monera, protista, fungi, plantae, and animalia. Together they form the tree of life.

Gram- bacteria stain pink due to the location of cell wall peptidoglycan and an external LPS membrane. Here's how Gram staining identifies Gram negative organisms.

Gram + bacteria stain purple due to the chemistry and structure of their peptidoglycan cell wall. Here's how Gram staining identifies Gram-positive organisms.

Penicillin is a common broad spectrum antibiotic used to treat many common infections. Though allergies can occur how safe is it to take a course of penicillin?

Genetics is the branch of science concerned with heredity in organisms, such as humans. What are genes, DNA, chromosomes and proteins - and where are they stored?

Organelles allow for many of the different required functions of the eukaryotic cell to be performed in specialized subcellular structures.
