Nobody knows!: - Only the Absorption on ALL'visible' Wavelength together (= Visible Spectrum) determine the color of what the Cuvette is containing!
Of course, that there are also 'Colors' outside the human "'Visibility'", and that also the Lambdamax is only an absolute Strongman to determine any Color!
(Even if all Universities tell it the other way!)

Which DNA nucleotide pair is most stable?
GC pairing is most stable and require maximum energy to dissoicate. This is reason that rate of DNA denaturation depends upon the GC content of DNA.
What part of DNA absorbs uv light?
In suntan lotion it is avobenzone and/or octyl methoxycinnamate. Many organic molecules (natural and man-made polymers) absorb UV. DNA absorbs UV-B (which can cause damage) - as can the cornea of the eye! The cornea also absorbs UV-A but seems to not suffer much with it. Much of the sun's UV-A, UV_B and UV_C radiation is absorbed by the Ozone Layer when it enters the atmosphere.
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"
One cell structure that cannot be seen with light microscopy?
Anything that is smaller than the wavelength of light, thatmeans that it is smaller than light and therefore is not visible, at all, to know it exists an electron microscope must be used which captures a reflection of the object a scanning electron microscope uses a computer to make the image
What is the study of genes and DNA?
The study of the DNA is the system where these stream of things that holds the data of the genetics information of your cell and that is what makes you dark light tall,short and all that things is have is by the DNA.
Why DNA absorb uv at 260 wavw length?
DNA absorbs in the ultraviolet range, at a wavelength ofabout 260 nanometers (nm); it absorbs at this wavelength because of the nitrogenousbases (A, G, C and T) of DNA.
Which requires a shorter wavelength to break- one of the bonds in the molecule Ozone or Oxygen?
Both ozone and oxygen absorb UV-C or more energetic light, and are broken apart by it. Only ozone can absorb the less energetic (longer wavelength) UV-B, to protect the DNA of surface life on Earth.
Why spectrophotometer is set in visible range 600nm while measuring bacterial turbidity?
When measuring light scattering it is important to consider the wavelength of light used a bacterial culture. Microorganisms may contain numerous macromolecules that will absorb light, including DNA (254 nm), proteins (280 nm), cytochromes (400-500 nm), and possible cell pigments. When measuring bacteria by light scattering it is best to pick a wavelength where absorption is at a minimum and for most bacterial cultures wavelengths around 600 nm are a good choice. However, the exact wavelength chosen is species specific. It is best to pick a wavelength where absorption is at a minimum.
How do uv rays light affect people?
they can cause skin cancer. It does this because the DNA molecules in your body absorb UV light, and the light has enough energy to break bonds in the DNA, causing harmful rearrangements in your genetic code. When cells with damaged DNA reproduce, that can result in cancerous cells.
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.
Why does cytochrome c absorb uv and visible light?
DNA absorbs UV light because of the aromatic rings of purines and pirimidines in its structure. DNA absorbs UV light because of the aromatic rings of purines and pirimidines in its structure.
When in a cells DNA content at its maximum?
In a normal cell, DNA content is at a maximum in G2 phase.
How does photolyase use light energy to repair DNA?
Photolyase works in conjunction with two co-factors. The first co-factor (either deazaflavin or methenyltetrahydrofolate) absorb a photon of light or a specific wavelength (in the blue spectrum) and passes this energy to FADH- which then acts as an electron donor, transferring a single electron to the pyramidine photodimer, and in doing so allows the bond between them to be broken.
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.... ......
Most of the DNA in eukaryotic cells is located in the?
glutius maximum
How do you find DNA concentration by UV method?
Measuring a solution containing DNA at 260nm is generally a good method of measuring DNA concentration. A standard curve is set up using known quantities of DNA and the unknown quantity is estimated by interpolation. RNA also absorbs UV radiation at roughly the same wavelength so one should be careful the measured sample is not contaminated with RNA. Proteins on the other hand, have a maximum UV absorbency at 280nm. By measuring the DNA sample at 260 and 280nm, one can estimate if the DNA is pure or not.
How do UV-B rays affect people?
UV light (particularly UV-B and UV-C, which are regions of the spectrum with shorter wavelengths than the UV-A part) can cause skin cancer. It does this because the DNA molecules in your body absorb UV light, and the light has enough energy to break bonds in the DNA, causing harmful rearrangements in your genetic code. When cells with damaged DNA reproduce, that can result in cancerous cells. See more details here: http://en.wikipedia.org/wiki/Ultraviolet
