DNA molecules are surrounded by water molecules when they are in solution. This is called the shell of hydration.
When the salt concentration of the solution is increased, the sale molecules replace the water molecules in the shell of hydration causing the DNA to come out of solution. This 'coming out' of the DNA from a soluble form is called DNA precipitation.
Precipitated DNA generally is surrounded by a lot of salt and has to therefore be placed in a low salt buffer in order to make sure it remains pure and integral (in an unbroken state)

What are DNA precursors?
dna precursors are the thing that make up dna, nucleotides
What is the purpose of using soap in a DNA extraction buffer?
The word detergent is used instead of soap in a DNA extraction buffer. Detergent is used to create a hydrophobic environment that favors the precipitation of proteins. Proteins are one of two major contaminants in DNA extraction (the other major contaminant being RNA). When protein precipitate, they can be separated by centrifugation and the DNA isolation procedure can continue.
What is made up of temperature precipitation and wind?
Weather
Are genes are made up of smaller molecules known as chromosomes?
No, chromosomes are made of genes and DNA. Gene sequences make up DNA, and this DNA is coiled up and makes up chromosomes.
The chromosomes are copied?
DNA makes up with chromosomes. The DNA is copied during DNA replication.
What are mechanism of heredity?
Heredity is the inborn factors which affect development. The mechanism of heredity is DNA. DNA is partially made up of pairs of "steps" called bases. Bases make up our genetic code. Chromosomes are coils of DNA, which are made up of small segments called genes.
Bakugan what is helix dragonoid DNA code?

What is the function of the chromatin in a plant?
Chromatin is the complex combination of DNA and protein that makes up chromosomes. The functions of chromatin are to package DNA into a small volume to fit in the cell, to strengthen the DNA to allow mitosis and meiosis, and to serve as a mechanism to control DNA expression and replication. Chromatin contains genetic material - instructions to direct cell functions.
Function of sodium acetate in DNA extraction?
Sodium chloride help to separate DNA from other proteins.
Is it the gene that contains the DNA or the DNA that contains the gene?
Chromosomes are made up of DNA. DNA is made up of genes.
How can you use DNA information?
DNA tells you who or makes up who you are DNA tells you who or makes up who you are
Structure of tRNA different from DNA?
tRNA is a single-stranded molecule that folds into a cloverleaf shape, while DNA is double-stranded and forms a helical structure. tRNA carries amino acids to the ribosome during protein synthesis, whereas DNA carries genetic information. tRNA contains modified nucleotides and often has loops and stems that are crucial for its function in protein synthesis.
What processes make up the water cycle?
Evaporation, Condensation, Precipitation, and there is also Collection
What is the climate and precipitation of the tropical Rain forest?
it gets up to 50 and 100 of precipitation each year
What is the Temperate rainforest Precipitation?
At least 200 cm of precipitation, perhaps up to 350 centimeters in warmer areas.
What is the precipitation in Italy?
Glad u asked.....the average precipitation for Italy is 6.2 in a year and up to .3 in a month
