kit that is used for dna extraction is called as dna extraction kit here the chemicals that are used for the extaraction are provided in the kit itself many biotech companies are selling those kits
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
If the DNA is not pure, contaminants include RNA and proteins
Trichloroacetic acid is used in DNA extraction to precipitate proteins and other contaminants from the DNA solution. This helps to separate the DNA from other cellular components, making it easier to isolate and purify the DNA for downstream applications.

Liquid detergent used in the genomic DNA extraction, emulsify plasma membrane and nuclear membrane promoting lysis. SDS (Sodium Dodecyl Sulphate) is an anionic detergent used in DNA extraction. It removes the positive ions from the proteins, due to this protein loses its conformation and gets destroyed thus the cell membrane gets damaged and cell gets broken.
Ethanol is used after the chloroform and isoamylalcohol mixture to precipitate DNA from the solution. Isopropanol is used during genomic DNA isolation to further facilitate the precipitation of DNA, ensuring a higher yield and purity of DNA in the final step.

Prepare the sample by collecting and processing it according to the kit's instructions. Follow the kit's protocol for cell lysis to release the genomic DNA. Add the necessary reagents and enzymes to the sample to purify the DNA. Use the provided columns or beads to separate the DNA from other cellular components. Wash the DNA to remove any contaminants. Elute the purified genomic DNA from the columns or beads using a suitable buffer. Store the extracted DNA properly for future use.
Prepare the bacterial sample by lysing the cells to release the DNA. Add reagents from the extraction kit to the sample to bind and purify the DNA. Centrifuge the sample to separate the DNA from other cellular components. Wash the DNA to remove any contaminants. Elute the purified DNA from the kit for downstream applications.
The TE buffer is used in DNA extraction to protect the DNA from damage and maintain its stability. It helps to maintain the pH level of the solution and prevent degradation of the DNA during the extraction process.

Glycerol is sometimes added to DNA extraction buffers to increase the density of the solution, allowing DNA to precipitate more efficiently. It also helps stabilize DNA during extraction procedures by preventing degradation from nucleases.
EDTA is used in DNA extraction processes to chelate divalent cations, such as magnesium, which are necessary for the activity of DNases that can degrade DNA. By removing these cations, EDTA helps protect the DNA from degradation during the extraction process.

Plant DNA extractionPlant genomic DNA is more difficult to extract because of the plant's cell wall, which is removed by homogenization, or by adding cellulase to degrade the cellulose that makes up the cell wall. Also, the metabolites present in the plant cell may interfere with genomic DNA extraction by contaminating the DNA sample during the precipitation process.Animal DNA ExtractionPeripheral blood leukocytes are a main source of animal genomic DNA, but sample collection is difficult as blood must be withdrawn from the animal. Blood contains a range of compounds like proteins, lipids, white blood cells, red blood cells, platelets, and plasma, which can contaminate the DNA sample. The primary contaminant of animal DNA extracted from blood samples is heme, the non-protein component of hemoglobin.DifferencesThe differences between plant and animal DNA lie in the sequence of bases in the helix. Compounds found in plant cells are absent in animal cells, and DNA base sequences reflect this, as the genomic plant DNA is often larger than animal DNA. These differences affect extraction methods, as it impacts on yield and purity of DNA.
