What key event happens during the s phase?
synthesis of DNA DNA Replication
What is DNA medicine?
DNA has largely replaced finger-prints for indentifying people. Or at least confirmed what finger-prints have led authorities to. Service people in the military today, all must now submit their DNA to the medical corps, so that in the event they become a casualty, they can be identified. DNA science has probably eliminated future "Unknown Soldiers." For detailed definitions of DNA, see site: DNA
Are genes a length of DNA?
Yes, a gene is a complex length of DNA that is in our body. A gene is a length of DNA that codes for a living life form. Genes are found on chromosomes which are in the body nucleus.
Did an African American contribute to the discovery of DNA?
No, DNA was first isolated by the Swiss physician. Also there were no African Americans involved in any subsequent work on DNA leading to the understanding of it structure.
When does DNA occur in the cell cycle?
All of it.The cell cycle describes the state of the DNA in the cell.
What is the role of beta-mercaptoethanol in DNA extraction?
stabilization of phenol against oxidation
What is the role of 2-mercaptoethanol in the isolation of genomic DNA from a plant source?
It is an antioxidant.
What role does a cheese cloth play in DNA extraction?
It plays a role.
What is the role of NaCl in DNA precipitation?
roll of Na CL in DNA extraction
Role of phenol chloroform isoamyl alcohol in plasmid DNA extraction?
The actual role of phenol chloroform isoamyl alcohol in a plasmid DNA extraction is to purify the DNA. The alcohol will act in part as a detergent.
What is the role of ethanole in DNA isolation?
2-Mercaptoethanol is often included in extraction buffers designed for plant DNA extraction, because it is a strong reducing agent which can remove tannins and other polyphenols often present in the crude plant extract. It may also help to denature proteins by breaking disulphide bonds between cysteine residues.
What is th role of dnazol in dna extraction?
lyses cells
Role of saline tris edta in DNA extraction?
Its purpose is to isolate DNA from a protein mixture.
Role of tris in extraction of DNA?
To give the solution buffering capacity.
What is the role of hot water bath in DNA extraction?
This question gave me cancer.
What is the role of mercaptoethanol in DNA isolation?
Mercapotoethanol is used as an antioxidant. Especially for polyphenolics which become insoluble when oxidised and tend to precipitate with the DNA. Sodium sulphite (1.2 g/L) does the same thing without the stink.
Role of beta-mecaptoethanol in DNA isolation?
beta- merceptoethanol denatures the protein by breaking the sulphur bridges in it.
