DNA absorbs in the ultraviolet range, at a wavelength of
about 260 nanometers (nm); it absorbs at this wavelength because of the nitrogenous
bases (A, G, C and T) of DNA.

What is DNA length?
One DNA strand is about 6 ft. in length.
What is the result after isolating DNA?
There are several things that can be done once DNA is purified. The first thing to do is to check its purity by measuring its 260 to 280 ratio. IN this method, the absorbency of the sample is measure at 260 and 280 nm. If the ratio of these two numbers is between 1.8 and 2.0, one can consider the DNA to be pure for further applications

Why does DNA absorb more light when it is converted into single strands?
in double stranded dna, the sugar phosphate backbone forms the the outside of the double helix and the information is found within (the complementary base pairs). When you heat up double stranded DNA, the DNA begins to unwind. The increases in temperature breaks the hydrogen bonds between the complementary base pairs and they now have become "unstacked" / exposed = (single stranded DNA). This allows the the single stranded DNA to absorb more light.
What does the charge of DNA have to do with DNA fingerprinting?
DNA is of a negative charge. So when gel electrophoresis is used on it the DNA fragments are attracted to the positive end of the electrophoresis. The fragments of different lengths travel down the gel towards this end. The longer length fragments travel less and so are farther from the positive end. By looking at these DNA fragments, which are created by cutting DNA with restriction enzymes one can compare and contrast DNA. Thus DNA fingerprinting can take place based on the different restriction sites in DNA (cut by the enzymes) forming different length segments of DNA.
What is DNA length?
One DNA strand is about 6 ft. in length.
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.
Can a developing baby absorb new DNA?
== == No ! The new cell (formating) take the DNA from sperm and ovul , XX XY,....you can not adjust more DNA after.... ......
DNA purity calculation OD280 equals 0.41 and OD 260 equals 0.82?

The length of a bacteriums DNA may be 1000 times the length of the cell within which it is contained how can this occur?
The bacterial DNA is highly coiled.
What is hypochromicity of DNA?
basically..hypochromicity is an effect showing by some compounds/substances (say DNA) a decreased absorbance of a wave length(chrome uses for colour,but) when it transformed physically (and in some extend chemically) to other state. here, a sample of double stranded DNA absorbs less amount of wavelength (for instance a 260 nm ultraviolet) compared to its same quantity of single stranded DNA molecules.. This decreased absorbance in terms of dsDNA can be termed as "DNA Hypochromicity"
Which is longer the circumference of the earth or the length of total DNA in your body?
Total dna

What is a length of DNA that codes for a protein?

Can you see DNA?
DNA is tightly coiled around histones when inside the nucleus of a cell. When uncoiled, DNA is around two inches in length.
