Repair DNA

Developing tricks and tools to keep their enzymes in order is one way thermophiles survive. They also use techniques to keep their DNA from falling apart under intense heat. Like proteins, the parts of the long, spiral ladder-shaped DNA molecule start to unravel and break apart under high hea... Read More

DNA Microarrays

If a microbiologist is studying bacteria that bioremediate, or break down, toxic wastes and wants to know which specific genes are active when that bacterium is degrading, say, PCBs, he would likely use a tool called the DNA microarray.


Microarrays enable scientists to monitor the act... Read More

Hunters and Grazers

Most fungi can best be described as grazers, but a few are active hunters.

Hunter fungi prey on tiny protozoa and worm-like creatures called nematodes.

Some produce a sticky substance on their hyphae, which then act like flypaper, trapping passing prey.

What They Eat


Fungi absorb nutrients from living or dead organic matter (plant or animal stuff) that they grow on. They absorb simple, easily dissolved nutrients, such as sugars, through their cell walls. They give off special digestive enzymes to break down complex nutrient... Read More

Algae


Algae also play an important role as the foundation for the aquatic food chain. All higher aquatic life forms depend either directly or indirectly on microscopic gardens of algae.

Most unicellular algae live in water, some dwell in moist soil, and others join ... Read More

Green Algae

The most clearly plant-like algae, this species gets its namesake hue from high levels of chlorophyll.


Their cell walls are made up of cellulose, the same material that makes up the cell walls in larger, multicellular plants. Like plants, they store the food they make through photosyn... Read More
