The role of NaCl or sodium chloride in RNA isolation is part of the denaturing process. It is often called the wash step.
Break open the cells, stabilize RNA, inhibit RNAse.
it solubilize the lipids and protein and remove them.
DEPC (diethylpyrocarbonate) is often used in RNA isolation to inactivate RNases, which are enzymes that can degrade RNA. DEPC is commonly added to water used in RNA isolation procedures to ensure that RNases are deactivated, thus helping to preserve the integrity of the RNA being isolated.
NaCl will not harm RNA. In fact, it is sometimes used as an elution buffer for RNA-Urea gels.
Sodium hydroxide (NaOH) is used in RNA isolation to disrupt cell membranes and denature proteins. At 1%, NaOH helps to increase pH, facilitating the release of RNA from cells and protecting it from degradation. It also helps to inactivate RNases, enzymes that can degrade RNA.
BCP bromo chloropropane is commonly used as a solvent for RNA isolation to disrupt cell membranes, denature proteins, and protect RNA from degradation. It helps to separate RNA from other cellular components during the extraction process, making it easier to isolate pure RNA for downstream applications such as reverse transcription and gene expression analysis.
MOPS buffer is used in RNA isolation to maintain a stable pH and prevent RNA degradation by RNases. It helps to protect RNA integrity during the isolation process, ensuring reliable results.
Carrier RNA is used in DNA isolation to help precipitate and recover DNA more efficiently. It acts as a carrier for the DNA during precipitation, helping to aggregate the DNA molecules together for ease of isolation. This improves DNA recovery and purity during the isolation process.
Trizol is a common reagent used for RNA isolation from biological samples. It works by disrupting cells and denaturing proteins to release RNA. Trizol also aids in the separation of RNA from other cellular components, allowing for efficient and high-yield RNA extraction.
Sodium acetate is used in RNA isolation to precipitate proteins and promote the efficient precipitation of RNA. It helps to remove unwanted proteins and other contaminants from the RNA sample, allowing for the isolation of pure RNA.
NaCl provides Na+ions which form ionic bond with the negatively charged phosphate of DNA,thus neutralizing the effect of negative ,negative repulsion of DNA and helps the DNA molecules to come closer and compact to simplify our process of DNA isolation...

Most often, RNA is removed using the enzyme RNAase
