Different bacteria have different optimal growth temperatures depending on their environments. Human gut bacteria thrive at 98 degrees Fahrenheit, while this same temperature would be lethal to most plant bacteria.Know More
Most bacteria found in everyday surroundings thrive at room temperature. Thermophilic bacteria, such as the bacteria present in the boiling hot springs of Yellowstone National Park and bacteria found around deep-sea thermal vents, thrive at high temperatures. Other bacteria thrive in cold temperatures, in Antarctic glaciers and waters. Such low-temperature bacteria can also grow in household refrigerators, making routine disinfection with an antiseptic necessary.
Different bacteria have different ranges of habitable temperatures, defined by the three cardinal phase-change points of water. Bacteria that prefer temperatures around those of warm-blooded animals are called mesophiles. Bacteria that prefer elevated temperatures of above body temperature but considerably below the boiling point of water at standard temperature and pressure conditions are called thermophiles. Bacteria that prefer temperatures around the boiling point of water are called extreme thermophiles. Bacteria that prefer the temperatures around the freezing point of water are called psychrophiles. Finally, bacteria that can survive and grow slowly at the freezing point of water but thrive at room temperatures are called psychrotrophs. These psychrotrophs are what cause frozen foods to spoil with time.Learn more about Molecular Biology & DNA
DNA replication is a process in which DNA is duplicated so that it can be integrated into a new cell during cell division. The process produces two identical replicas of the DNA molecule from one original DNA molecule. It occurs in every living organism on Earth, allowing parental generations to pass on genes to their offspring.Full Answer >
Chromosomes are located in the nucleus of every cell found in both plants and animals. These structures are thread-like substances that are comprised of proteins and one single DNA molecule. Each chromosome in the human body and in plants contains one molecule of DNA that signals cells to repair themselves and function properly.Full Answer >
The five-carbon sugar found in RNA is ribose. Ribose is an important carbohydrate for generating energy in the cells of living organisms.Full Answer >
"Noncoding" refers to a strand of DNA that does not contain the information that the body needs to create proteins. DNA contains a coding strand and a noncoding strand. The two strands are mirror images of each other, but only the coding strand has the information for making proteins.Full Answer >
