Microbial chronometers (also called molecular chronometers) are, "nucleic acid and protein sequences that gradually change over time in a random fashion and at a steady rate, and which therefore can be used to determine phylogenetic relationships." Molecules that are sometimes used as chronometers include ATPases, however you cannot compare the ATPases that are used in respiration and fermentation due to their divergence, only same function molecules may be compared. AAtRNA synthetases, these may become the new standard way to define the phylogenic relationship of organisms due to their highly conserved nature. RecProteins, used in recombination however they are not very well conserved and so using them is not recommended (the most effective chronometer is highly conserved). Currently the small subunit of the ribosome is used (16s in prokayotes and 18s in eukaryotes) due to its conserved nature and presence in all organisms.
No. A chronometer measures time. Wrist watches, egg timers, and hour-glasses are chronometers.
A marine chronometer measures time. It is a very precise instrument because it can also be used to measure the longitude of the ship at sea using the time shown and the angle of the sun.
Microbial loading refers to the amount of microorganisms present in a given environment, such as air, water, or surfaces. It is a measure of microbial contamination and can be quantified by assessing the concentration or number of viable microorganisms in a sample. High microbial loading can increase the risk of infection or spoilage.
Measuring microbial growth is important because it helps monitor the progress of experiments, assess the efficacy of antimicrobial agents, ensure food safety, and understand the dynamics of microbial populations in various environments. By quantifying microbial growth, researchers can make informed decisions and take necessary actions to control or manipulate microbial populations.
A microbial guild refers to a group of microbes with shared metabolic functions or interactions, often working together to perform specific tasks. In contrast, a microbial community is a broader term that includes all microbial populations living in a particular ecosystem, encompassing various guilds and individual species. Essentially, a guild is a specialized group within a community.
"Chronometer" is a noun.

she frequently referred to use a clock as a chronometer Meaning chronometer is a more accurate word for "clock" :)
A chronometer is a watch that is designed for the highest amount of precision and accuracy. The time on a chronometer watch is almost always accurate.
She frequently referred to any clock as a chronometer .
Long before GPS, an accurate chronometer was needed to help a ship determine Longitude.

No, not all Rolex watches are Chronometer certified. Rolex offers both certified and non-certified models in their lineup. Chronometer certification guarantees accuracy within specific standards set by the Swiss Official Chronometer Testing Institute (COSC).
No. A chronometer measures time. Wrist watches, egg timers, and hour-glasses are chronometers.
A chronometer is very accurate timepiece. It was critical in being able to navigate on the oceans. The creation of a reliable and accurate chronometer was one of the things that made Britain the ruler of the oceans for a long time.

You would possibly use a chronometer which is an extrememely accurate clock.You would possibly use a chronometer, a very accurate clock.
