DNA extraction is done by three methods: * Organic extraction * inorganic extraction * solid state method In organic extraction, phenol and chloroform are used to create on organic phase in which cells are lysed and DNA is freed. The DNA remains in the aqueous phase. Ethyl alcohol is used to precipitate the DNA. In the inroganic methos, NaCl and EDTA are used for cell lysis. Following this, an approach similar to the organic method is followed. In solid state extraction, DNA is first precipitated in the presence of high slat and low pH conditions. The precipitated DNA is then adsorbed on to a filter membrane surface.
What else can I help you with?
What molecules are present in cells that might interfere with DNA extraction?
Molecules that can interfere with DNA extraction include proteins, polysaccharides, lipids, and polyphenols. These molecules can bind to DNA, causing it to be more difficult to extract or making the DNA susceptible to degradation during the extraction process. It is important to use appropriate methods to remove or inhibit these molecules before extracting DNA from cells.
Have you had any experience using the Qiagen Total RNA Extraction Kit for your RNA extraction needs?
I have not personally used the Qiagen Total RNA Extraction Kit for RNA extraction.
How is RNA different from DNA in terms of their structures and functions?
RNA is different from DNA in terms of structure and function. Structurally, RNA is single-stranded while DNA is double-stranded. Functionally, RNA is involved in protein synthesis and gene regulation, while DNA stores genetic information.
How is the structure of RNA different from DNA?
RNA is single-stranded, while DNA is double-stranded. RNA contains the sugar ribose, while DNA contains deoxyribose. RNA has the base uracil instead of thymine found in DNA. Additionally, RNA is typically shorter in length compared to DNA.
How is the structure of RNA different from the structure of DNA?
RNA is single-stranded, while DNA is double-stranded. RNA contains the sugar ribose, while DNA contains deoxyribose. RNA has the base uracil instead of thymine found in DNA.
What is the function of CL buffer in DNA extraction?
In a DNA extraction, the purpose of a buffer is to solubilize DNA as well as RNA. Because of this, it prevents the DNA for degrading.

If the DNA in a DNA extraction is not pure what other types of molecules might be present?
If the DNA is not pure, contaminants include RNA and proteins
What is the purpose of RNA extraction?
RNAse destroys the RNA and hence RNAse contamination is a problem in RNA extraction as it breaks down RNA. RNAse enzyme is removed by using RNAse inhibitor or precautions like wearing of gloves, autoclaving tips , using RNAse free water/DEPC treated water is done while performing RTPCR
Are DNA and RNA carbohydrates?
Yes, DNA and RNA have different sugar . DNA contains deoxyribose sugar whereas RNA consists of ribose sugar, which are completely different from each other.

Role of te in dna extraction?
TE stands for Tris and EDTA. The Tris buffers the water to prevent acid hydrolysis of the DNA/RNA. The EDTA chelates divalent cations that can assist in the degradation of RNA.

Why is RNA primase not DNA primase?
RNA primase is used to synthesize short RNA primers that are needed for DNA replication by DNA polymerase. This RNA primer can be easily replaced by DNA once DNA polymerase starts synthesizing the new DNA strand. This is different from DNA primase which synthesizes RNA primers during the synthesis of Okazaki fragments on the lagging strand during DNA replication in prokaryotes and eukaryotes.
