What is the use of guanidine isothiocyanate and NaOAc in the isolation of RNA?
Chiqktan
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 1 percent of NaOH in the isolation of RNA?
it helps in precipition step...
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 function of Licl in RNA isolation?
Large molecules of RNA gets aggregates with the LiCl2 approx 3M solution and helps in proper precipitation. remember let the mixture hold overnight in 4c.
Which type(s) of RNA is (are) involved in protein synthesis?
The three main types of RNA directly involved in protein synthesis are messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). The mRNA carries the message from the DNA, which controls all of the cellular activities in a cell. In prokaryotes and eukaryotes, tRNA and rRNA are encoded in the DNA, then copied into long RNA molecules that are cut to release smaller fragments containing the individual mature RNA species.
Does RNA contain phosphoric acid?
RNA has phosphoric acids
What is the role of DEPC in RNA isolation?
It inactivate the RNase and prevent RNA to denature.
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 TRIreagent in RNA isolation?
Break open the cells, stabilize RNA, inhibit RNAse.
How is RNA removed from DNA during DNA isolation?
Most often, RNA is removed using the enzyme RNAase
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?

What does RNase solution do in the Isolation of genomic DNA from Negative bacteria?
Digests RNA molecules
How can you tell if isolated RNA is free of DNA?
There is a DNA killing step in RNA isolation by the enzyme DNase I. This will make sure your preparation is free of DNA.
Role of trizol in RNA isolation?
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.
