What is the function of ethylene diamine tetraacetic acid in DNA isolation?
Ethylene diamine tetraacetic acid (EDTA) is a chelating agent commonly used in DNA isolation to sequester divalent metal ions, such as Mg2+, that are required by nucleases to degrade DNA. By removing these metal ions, EDTA helps to inhibit the activity of nucleases and stabilize the DNA during the isolation process.
What are the function of sodium acetate in dna isolation?
Sodium acetate is used in DNA isolation as a salt to promote DNA precipitation, helping to remove contaminants and impurities from the DNA sample. It is commonly used in combination with ethanol to precipitate DNA from solution, allowing for the extraction and purification of DNA for further analysis. Sodium acetate also helps to maintain the appropriate pH level for DNA precipitation to occur effectively.
What is the function of phenol in dna isolation?
Phenol plays a role in DNA isolation by helping to separate DNA from proteins and other contaminants. It is used in a phenol-chloroform extraction step to denature proteins and lipids, allowing DNA to remain in the aqueous phase while these contaminants are removed into the organic phase. This helps to purify the DNA sample for downstream applications.
What is the role of carrier RNA in DNA isolation?
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.
What acid is required for mature erythrocytes called?
Mature erythrocytes require folic acid for their development and function. Folic acid is important for red blood cell production and maturation, as it is needed for DNA synthesis.

Role of sucrose in DNA isolation from human blood?
Sucrose is used in DNA isolation from human blood as a protective agent to help maintain the integrity of the DNA during the isolation process. It helps to stabilize the DNA by providing a protective barrier against enzymes and other degradation factors present in the blood sample. Additionally, sucrose can aid in the separation of DNA from other cellular components during the isolation procedure.
Which macromolecule determines the structure and function of a cell?
deoxyribonucleic acid (DNA)
Role of Glacial acetic acid in plasmid isolation?
Glacial acetic acid is used in plasmid isolation to precipitate proteins during the process of plasmid DNA purification. It helps separate the plasmid DNA from proteins, RNA, and other contaminants, allowing for the collection of purified plasmid DNA. Additionally, acetic acid helps maintain the pH of the solution, facilitating the precipitation of contaminants while keeping the plasmid DNA soluble.
What is the function of STET buffer in plasmid isolation?
STET buffer is used in plasmid isolation to stabilize the plasmid DNA, prevent degradation by nucleases, and maintain the pH of the solution. It is a commonly used buffer for preserving DNA during the extraction process.
What is the function of sodium citrate in DNA isolation?
Sodium citrate is used in DNA isolation to prevent DNA degradation by chelating divalent cations such as magnesium and calcium, which can act as cofactors for DNases. By binding these ions, sodium citrate helps to stabilize the DNA and protect it from enzymatic degradation during the isolation process.

What provides the information for cell growth and function What is the word for it?
DNA provides the information for cell growth and function.
Function of tris HCl in DNA isolation?
Tris HCl is used as a buffer in DNA isolation to maintain a stable pH level during the process. It helps to prevent pH fluctuations that can affect the integrity of the DNA molecule. Tris HCl also aids in the solubilization of proteins and DNA, ensuring efficient extraction of DNA from the sample.
Where is DNA and RNA stored in the body?
Deoxyribonucleic acid (DNA) is two strands of Ribonucleic acid (RNA) that have been put together. See http://nobelprize.org/educational_games/medicine/dna/index.html for a more detailed answer.
Which nucleic acid does not carry out its function in the ribosome?
DNA does not carry out its function in the ribosome. DNA's main function is to store genetic information, which is then transcribed into messenger RNA (mRNA) to be translated in the ribosome to produce proteins.
