The chemical basis of Chargaff"s rule is the bonding properties of the DNA bases.
Explanation:
According to the Chargaff"s rule in a DNA molecule the total number of purine bases are equal with the total number of pyrimidine bases that means
Adenine +Guanine=Thymine +Cytosine
In simple words the rule is based on the 1:1 ratio of both purine and pyrimidine bases.
I just think your overthinking a bit..buh I definitely been in your place before (when iwas bored and didn't hav anything else to think about) lol I still think thats a good questiond tho xD
<h2>Advantages of ATR in IR-Spectroscopy</h2>
Explanation:
- ATR allows for the use very small samples.
- Sample preparation and clean up of an ATR is simple.
- This is because The ATR crystal is not degraded by the presence of water. The ATR method is advantageous because the ZnSe crystal sample holder
:
- Can accept very small quantities of solids or liquids.
- Is not degraded by the presence of water.
- Clean up is usually easy
.
- Beam-through-sample instruments use sample plates that are made from sodium chloride or potassium bromide and are easily damaged by contact with water; they must never be held with bare hands or washed with water.
- The plates are also fragile and will easily chip or crack. Spectra of polar protic materials recorded on a beam-through-sample instrument may suffer from diminished resolution due to interactions between the sample and the salt plate.
