What is the role of the ethanol in the purification of DNA?
pinecones
Role of spooling in blood DNA isolation?
spooling of the DNA results from the addition of the ethanol which is insoluble in the solution. after we get he DNA in the form of spooling structure the solution is centrifuged. so we get the DNA.
What is one role of ribonucleic acid (RNA) in organisms?
It is the messenger between DNA and the protein-synthesis ribosomes.
What is one of the role of ribonucleic acid RNA in organisms?
It is the messenger between DNA and the protein synthesis ribosomes
What is the role of buffering?
Buffers are chemical substances that neutralize small amounts of either an acid or a base added to a solution.
What is the role of sulphuric acid in the reaction?
It's a acid, so it lowers the pH and enzymes only work at a specific pH, so it will stop and slow the reaction down.
Which is selective oxidised ethanol or ethanoic acid?
Role of the reductant (electron donor)1) First step: from ethanol to ethanalCH3CH2OH --> CH3CHO + 2H+ + 2e- (ethanal, acethaldehyde)2) Second step: from ethanal to ethanoic acidCH3CHO + H2O --> CH3COOH + 2H+ + 2e- (ethanoic acid, acetic acid)Role of oxidant: (electron acceptor)4H+ + 4e- + (oxidant, e.g.:) O2 --> 2H2O
What is the role of ethanol in saponification?
ethanol allows oil to be able to mix with water.
What is the role of the mineral acids in the esterification process?
esterification is between an organic carboxylic acid and alcohol but sulphuric acid is required in mechanism which converts the carboxylic acid molecule into a carbonium ion which reacts with alcohol and forms an ester.
What is the role of the ethanol in the purification of DNA?
pinecones
H2SO4 in aspirin?
Yes. ^ Well to improve on this, in simple terms. A catalyst is something that brings on the reaction, in this case the liquid catalyst can only contain a little amount of water otherwise side reactions will occur and this would impact (reduce) the yield of aspirin - not good, sulfuric acid is usually used because it is 98% pure, phosphoric acid can also be used but it is only about 85% pure, still OK. HCL in its most concentrated form is only 37% pure and there fore no good at all. In a shorter to the point answer, H2SO4 is a pure catalyst which will give you a close to accurate yield of aspirin.
What is the role for nitric acid?
The role of nitric acid in anal sex? To destroy the innards of the idiot who used it.
What system plays a role in defending the body from harm?
The integumentary system protects the body from injury, infection, and dehydration.
What role does stomach acid play in digestion?
Hydrochloric acid Hydrochloric acid
What is a single strand nucleic acid that plays a role in protein?
Ribonucleic acid
Why do Asians get drunk faster and sober faster?
A larger percentage of persons of Asian decent, have a dominant gene mutation which interferes with the role of an enzyme called acetaldehyde dehydrogenase. The role of this enzyme is to convert acetaldehyde, a metabolite of ethanol (alcohol), into acetic acid. Persons with this mutation therefore experience higher levels of acetaldehyde in their systems when they consume alcohol.
What is a single stranded nucleic acid that plays a role in protein synthesis.?
Ribonucleic acid
