How to calculate specificity?, please specify ^^
The answer very much depends on the object. There are many formulas for areas of many common objects. Sometimes there is not formula and you must approximate it. Unfortunately, the question lacks enough specificity to be answered.
Any instrument with which you measure can only have a finite degree of specificity, and you will always have error within that degree of specificity. For example, using a meter stick that includes centimeters and millimeters, and the human eye a person can measure the length a stick, and by looking at the millimeter marks decide if the length is closer to 3.4 centimeters or 3.3 centimeters. In actuality, the length is something in between, but the person can only report what they see, so if the end of the stick is closer to 3.4 than 3.3, they will say 3.4. In this case, the error is .05 cm (or .5 mm) because you can only detect lengths as being more or less than halfway between two mm marks. A better ruler might have marks between the mm marks. You could imagine someone with really great vision who could see .1 mm on this special ruler. So they might be able to tell that the stick is closer to 3.43 cm than 3.44 cm, but that's as precise of a decimal as they could report, because the measuring instrument (the ruler) only includes marks for .1 mm (or .01 cm). The maximum error in this case would be .005 cm (or .05 mm) because the person can tell the stick is less than halfway between 3.43 and 3.44, but cannot decipher more than that. Any measuring instrument, not jut rulers, comes with a finite level of specificity. The maximum error is half of that level of specificity. A scale that reports weight only in whole pounds would have maximum error of .5 lbs, while a scale that reports weight in tenths of a pound would have a maximum error (or uncertainty of measurement) of .05 lbs.
Yes, this is true (generally speaking). In many cases there are two different codons that differ at the third position yet code the same amino acid. I hypothesize that the reason that this is so is that nature has naturally selected the codons to be resistant to certain transition and transversion mutations. transition mutation = purine to purine or pyrimidine to pyrimidine transversion mutation = purine to pyrimidine or pyrimidine to purine
The reciprocal of 1 is 1. Proof: a. 1*(1/1) = 1 because a*(1/a) = 1 b. 1*1 =1 because 1*a = a c. 1/1 = 1 compare a. and b.
1) absolute specificity 2) Group specificity 3) Linkage specificity 4) Stereochemical specificity
what is the role of HCL in the DNase experiment
Serratia genus as a whole is dnase positive.
There are no reagents added when a Dnase test is performed. The test is done in a methyl green medium with a pure inoculum culture. If halos form around the culture than Dnase is present.
nope.
it is chealeting agent and has great affinity with metal ions and mg- ions present in dnase as a cofactor and responsible for dnase action that degreded DNA hear edta bide with mg- ions and stop the action of dnase.
DNase (deoxyribonuclease) is an enzyme. It is manufactured by ribosomes and can undergo post translational modifications or cotranslational modifications. DNase catalyzes the hydrolytic cleavage of phosphodiester linkages in the DNA backbone. A wide variety of is known, which differ in their substrate specificities, chemical mechanisms, and biological functions.
Yes
DNase I: deoxyribonuclease
'Cuz you touch yourself at night.
The anti-DNase-B (ADB) test is performed to determine a previous infection of a specific type of Streptococcus, group A beta-hemolytic Streptococcus.
hii I'm a student I need 2mg/ml DNase for my working but I have 1000 unit stok DNase(1 u/ul) I don't know how I calculate from unite to ml please help me thank you very much
