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.
the things what we learn from microbial
Enzyme present in microbes are called microbial enzymes .
Microbial death occurs when bacteria run out of nutrients and die.
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.
"Chronometer" is a noun.
Chronometer Chronometer
John Harrison invented the chronometer
she frequently referred to use a clock as a chronometer Meaning chronometer is a more accurate word for "clock" :)
She frequently referred to any clock as a chronometer .
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.
The chronometer was invented in the year 1761. The chronometer was actually invented by John Harrison in 1735. It was 1761 that he finally got it up to the standards that were accepted by the British Navy.
Long before GPS, an accurate chronometer was needed to help a ship determine Longitude.

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.
