Understanding Prokaryotes: Their Shapes, Functions, and Genetics

Prokaryote Basics
Ever wonder what the tiniest living things on Earth are? That's prokaryotes - microscopic organisms that have been around for 3.5 billion years! They come in three basic shapes: rod-shaped bacillus, circular coccus, and spiral spirillum.
Prokaryotes are single-celled organisms (unicellular) but can form communities called biofilms. Their genetic material consists of a single circular double-stranded chromosome and often small DNA circles called plasmids. They reproduce through binary fission - essentially making copies of themselves.
What makes prokaryotes special is their ability to share genetic material through horizontal gene transfer. Unlike sexual reproduction, this process allows prokaryotes to exchange genes between existing cells, creating genetic diversity without producing offspring.
Fun Fact: Two of the three domains of life are prokaryotes (Bacteria and Archaea), but they're actually very different from each other. Archaea are genetically closer to eukaryotes (like us!) than to bacteria.
Bacteria vs. Archaea: Structural Differences
Bacteria and Archaea may look similar under a microscope, but they're actually as different as cats and trees! The biggest differences are in their cell structures and molecular makeup.
Their plasma membranes are built differently. Bacteria have fatty acid chains attached to glycerol with ester linkages, while Archaea use isoprenoids connected with ether linkages. This gives Archaea membranes that can be branched or even form a monolayer rather than the standard bilayer.
The cell wall composition is another major difference. Bacteria have cell walls made of peptidoglycan, but Archaea lack this compound completely. Even their DNA replication processes differ, with Archaea using machinery more similar to what we eukaryotes use.
Remember This: Archaea were once thought to be just weird bacteria, but they're so different they deserved their own domain! These differences help Archaea survive in extreme environments where other organisms can't.
Cell Wall Structures and Bacterial Appendages
The cell wall is like a prokaryote's armor! It maintains the cell's shape and protects it from bursting in water-rich environments. Bacteria come in two main types based on their cell wall structure: Gram-positive bacteria have a thick peptidoglycan wall, while Gram-negative bacteria have a thinner layer.
Many bacteria have additional external structures that help them survive. A capsule is a sticky, gelatinous layer that helps some bacteria attach to surfaces and resist your immune system's attacks. Flagella are protein propellers that spin like tiny motors, allowing bacteria to swim through liquids.
Some bacteria also have pili - short, hair-like structures found in Gram-negative bacteria. These help bacteria stick to surfaces and can even create bridges between cells for DNA exchange during a process called conjugation.
Critical Insight: Many antibiotics specifically target the bacterial cell wall, which is why they can kill bacteria without harming your cells (since human cells don't have cell walls).
Bacterial Survival Structures and Classification
When conditions get tough, some bacteria form endospores - highly resistant structures that protect their DNA and essential components. These super-resistant forms can survive extreme heat, radiation, and even some disinfectants! Bacteria that cause serious diseases like tetanus, botulism, and anthrax form endospores.
Inside bacterial cells, you'll find the nucleoid region containing their circular chromosome and sometimes plasmids. They also have ribosomes that make proteins, though these are smaller than the ones in your cells and are targeted by some antibiotics.
Scientists used to classify bacteria based on characteristics like shape, mobility, and whether they cause disease. Today, we use more precise methods like DNA sequencing, analyzing protein structures, and comparing G-C content (the percentage of guanine and cytosine bases in their DNA).
Wow Moment: Endospores are so hardy that some have remained viable for thousands of years! Scientists have successfully revived bacterial endospores from ancient samples.
Prokaryotic Genetics and Gene Transfer
Even though prokaryotes don't have sex, they still swap genes! While they reproduce by making identical copies through binary fission, they create genetic diversity through three types of horizontal gene transfer.
In transformation, bacteria take up DNA fragments from their environment, often from dead cells. Transduction occurs when viruses accidentally package bacterial DNA during infection and deliver it to new cells. The most direct method is conjugation, where bacteria connect through pili and transfer DNA directly to each other.
These gene transfers can give bacteria new abilities, like antibiotic resistance. Resistance plasmids containing genes for antibiotic resistance can spread quickly through bacterial populations, which is why antibiotic overuse is such a concern.
Real-World Impact: The spread of antibiotic resistance genes through horizontal gene transfer is one of the biggest public health challenges today. That's why it's so important to use antibiotics only when necessary!
Prokaryotic Metabolism and Human Diseases
Prokaryotes are metabolic champions! They get carbon and energy in diverse ways. Autotrophs make their own food from CO₂, either using sunlight (photoautotrophs) or by oxidizing inorganic compounds (chemolithoautotrophs). Heterotrophs get carbon from organic molecules, with some using light for energy (photoheterotrophs) while others, like us, get both carbon and energy from food (chemoheterotrophs).
Some bacteria cause serious diseases in humans. Tuberculosis affects the respiratory system and is the second most common cause of death after HIV/AIDS. Peptic ulcers, once thought to be caused by stress, are actually caused by the bacterium Helicobacter pylori and can be treated with antibiotics.
Even our teeth aren't safe! Dental caries (tooth decay) happens when bacteria like Streptococcus sobrinus form biofilms on teeth, ferment sugar to acid, and degrade your tooth enamel.
Knowledge Check: Humans are chemoheterotrophs - we get both our carbon and energy from the organic molecules in our food. How many of the other metabolic types can you remember?
Introduction to Viruses
Are viruses alive? That's debatable! They have a simple structure: a nucleic acid core (DNA or RNA) surrounded by a protein shell called a capsid. Many animal viruses also have an outer envelope for protection. Outside a host cell, viruses exist as inactive particles called virions.
Viruses come in various shapes, with the two main ones being helical and icosahedral (roughly spherical with 20 triangular faces, like a soccer ball). Each virus type can only infect specific hosts (host range) or even specific tissues within a host (tissue tropism).
Viruses can't reproduce on their own - they're basically just genetic instructions that hijack your cells' machinery. They lack ribosomes and enzymes for making proteins or nucleic acids, so they must infect cells and use the host's transcription and translation systems to create more viruses.
Mind Blower: There are more types of viruses on Earth than all other organisms combined! And many viruses can remain dormant in your body for years before reactivating.
Viral Genomes and Replication Cycles
Viral genomes are incredibly diverse. Some contain DNA while others use RNA. They can be single or double-stranded, with most RNA viruses being single-stranded. RNA viruses replicate in the host cell's cytoplasm and have high mutation rates, which makes developing vaccines against them challenging.
Bacteriophages are viruses that infect bacteria, and they replicate through two main cycles. The lytic cycle works quickly: the virus attaches, injects its genetic material, hijacks the cell to make viral components, and then causes the cell to burst (lyse), releasing new viruses. The lysogenic cycle is stealthier: the virus integrates its genome into the bacterial chromosome and remains dormant until conditions are right.
Some viruses can undergo antigenic shifts - major changes in their surface proteins that can lead to pandemics. For a pandemic to occur, the virus must contain new combinations of surface proteins, be able to cause disease in humans, and be efficiently transmitted between people.
Critical Understanding: Giant viruses like Mimivirus and Pithovirus challenge our definition of viruses. Some encode their own DNA replication machinery and are larger than some bacteria!
