trizol helps in maintaining the integrity of the RNA and keeps it intact since RNA is very unstable due to the presence of hydroxyl groups which gives it a free radical.

What is the role of DEPC in RNA isolation?
It inactivate the RNase and prevent RNA to denature.
While loading total RNA in farmaldehide gel a streek pattern is showing above the well in opposite direction of RNA movement and also band is very light in gel WHY?
its ethidium Bromide that's moving out!!!!! check with the amt of rna loaded!and its quite possible the isolation is bad... how is the o.dAnswerits ethidium Bromide that's moving out!!!!! check with the amt of rna loaded!and its quite possible the isolation is bad... how is the o.d
What molecule builds the new strand of RNA during transcription?
RNA Polymerase plays the largest role in unzipping the DNA strand and then synthesizing the RNA strand.
Role of sucrose in DNA isolation from human blood?
Sucrose performs the function of osmoregulation in the protocol of DNA isolation from blood
What is the role of introns in gene regulation?
Introns are removed through RNA splicing. They don't play a role.
What is the role of NaCl in RNA isolation?
The role of NaCl or sodium chloride in RNA isolation is part of the denaturing process. It is often called the wash step.
What is the role of DEPC in RNA isolation?
It inactivate the RNase and prevent RNA to denature.
What is the role of TRIreagent in RNA isolation?
Break open the cells, stabilize RNA, inhibit RNAse.
Role of chloroform in RNA isolation?
it solubilize the lipids and protein and remove them.
What is role of BCP bromo chloropropane in RNA isolation?
for phase separation
What is the role of 1 percent of NaOH in the isolation of RNA?
it helps in precipition step...
What is the use of guanidine isothiocyanate and NaOAc in the isolation of RNA?
Guanidine isothiocyanate helps denature proteins from the RNA to allow them to be separated from protein for the best isolation of nucleic acids from proteins (can collect all 3 if using TRIzol like reagents)NAoAc (sodium acetate) usually in 3M/pH8 is used later in the steps for nucleic acid isolation as the salt for ethanol precipitation. If you are going to be doing RNA transcription off of DNA templates that you are precipitating, it is best to use Nh4oAC (ammonium acetate) as the ion is nicer to RNA polymerases once templates are cleaned and being transcribed.
What is the role of carrier RNA in DNA isolation?
Carrier RNA reduces the pKa of the silica membrane and electrostatic repulsion between DNA and the column, thereby increasing the adsorption of DNA to the column
What is the Role of RNAase in plasmid preparation?
In plasmid isolation RNA behaves as an unwanted material so to separate it out RNAase is required which breaks down the RNA. This is done to get pure quality of the product.
What is the chemical molecular formula for Trizol?
guanidinium thiocyanate, sodium acetate, phenol and chloroformP. Chomczynski and N. Sacchi, "The single-step method of RNA isolation by acid guanidinium thiocyanate-phenol-chloroform extraction: twenty-something years on," Nature Protocols, vol. 1, no. 2, pp. 581-585, 2006.
How is RNA removed from DNA during DNA isolation?
Most often, RNA is removed using the enzyme RNAase
What is the function of MOPS buffer RNA isolation?
It act as a buffer in Northern blotting.
