What macromolecule assembles into bilayers?
Phospholipids have a hydrophobic tail, but a hydrophilic head. Self- assembles into micells or bilayers, an important part of cell membranes.
Which organisms has the best potential to survive in extreme environments?
Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.
What is true about biofilms quizlet?
Biofilms occur in nature but rarely occur in human infections. The microbes in biofilms can work cooperatively to carry out complex tasks. Before bacteria can be identified, mixed cultures must be separated. What technique is used to separate bacteria and get individual colonies?
What are the four major types of microbes?
The major groups of microorganisms —namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below.
What are the methods or techniques used in manipulating DNA?
Basic techniques used in genetic material manipulation include extraction, gel electrophoresis, PCR, and blotting methods.
What are four types of macromolecules found in living things?
The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
Is a virus a macromolecule?
Viruses are similar in size to a large protein macromolecule, generally smaller than 200 nm in diameter. Viruses, like cells, carry genetic information encoded in their nucleic acid, and can undergo mutations and reproduce; however, they cannot carry out metabolism, and thus are not considered alive.
Why was RNA the original genetic material?
The hypothesis posists that DNA later became the genetic material as a result of evolution because RNA was a relatively unstable molecule. According to the RNA World Hypothesis, around 4 billion years ago, RNA was the primary living substance, largely due to RNA’s ability to function as both genes and enzymes.
What organisms are found in extreme environments?
Extremophiles are organisms that live in ” extreme environments,” under high pressure and temperature. Bacteria often form on the rocks near the hydrothermal vents.
What are examples of extreme environments?
Examples of extreme environments include the geographical poles, very arid deserts, volcanoes, deep ocean trenches, upper atmosphere, outer space, and the environments of every planet in the Solar System except the Earth.
What are 5 of the most extreme conditions that bacteria can live?
Extremophiles are organisms that have been discovered on Earth that survive in environments that were once thought not to be able to sustain life. These extreme environments include intense heat, highly acidic environments, extreme pressure and extreme cold.
What role does biofilm play in disease quizlet?
Biofilms are responsible for a large number of disease in humans as these structures are intrinsically resistant to antibiotics and also to host defence systems. The diseases are therefore very diificult to cure. The bacteria growing in slime enclosed aggregate have also important role in chronic infections.
Which of the following is an example of a biofilm quizlet?
Which of the following is an example of a biofilm? Bacteria growing in plaque.
What are examples of biofilms?
Microorganisms that form biofilms include bacteria, fungi and protists. One common example of a biofilm dental plaque, a slimy buildup of bacteria that forms on the surfaces of teeth. Pond scum is another example. Biofilms have been found growing on minerals and metals.
