Only the deoxyribose after heating becomes furfural which then reacts with DPA and produces dark blue coloured compond which can be estimated on the other hand one can say that orcinol does't reacts with deoxyribose similarly DPA does't reacts with ribose
Yes, DNA and RNA have different sugar . DNA contains deoxyribose sugar whereas RNA consists of ribose sugar, which are completely different from each other.
DNA is replicated.
Because DNA is unique to each person so it can be used to kinda say they were definatly involvd cos it couldn't be anyone else's DNA
DNA atomic structure - X-ray crystallography DNA base sequencing - Polymerase Chain Reaction in conjunction with gel electrophoresis. DNA function - splicing DNA fragments into plasmids, then infecting host bacteria. Other methods include heredity studies. J Ayres
Cold water is better for extracting DNA because it helps stabilize the DNA structure, reducing the likelihood of degradation. Additionally, cold temperatures slow down enzymatic activity, minimizing the risk of DNA digestion by nucleases that can be active at warmer temperatures. This preservation of DNA integrity is crucial for successful extraction and subsequent analysis.
Common methods for DNA estimation include spectrophotometry using UV absorbance at 260 nm, fluorometry using DNA-intercalating dyes such as Hoechst or PicoGreen, and quantitative PCR (qPCR) using specific primers to amplify and quantify DNA fragments. Each method has its own advantages and limitations, so selection should be based on the specific requirements of the experiment.
Strangers typically share less than 1 of their DNA with each other.
in DNA estimation by diphenylamine method, standard calf thymus DNA is digested by perchloric acid, but unkown is not digested by perchloric acid, rather rest protocol of diluting with water and treating with diphenylamine and checking aborbance reamins same can anybody say the reason?
DNA (deoxyribonucleic acid) is the 'language' that genes are 'written in'. The DNA in the nucleus composes the genome (complete set of genes) of the organism to which the cell belongs. Thus the human genome is the genome of the DNA within the nucleus of human cells. But DNA, in plants and other photosynthetic eukaryotes, is found composing a completely different genome within the chloroplasts. And in most eukaryotes including animals, plants and fungi, their is also a separate mitochondrial genome composed from DNA in the mitochondria. The theory of endosymbiosis explains the presence of DNA in mitochondria and chloroplasts.

When extracting DNA from cheek cells, you may also find bacterial DNA that naturally reside in your mouth, as well as any DNA from food or other substances that have come in contact with your mouth. These other sources of DNA can be present alongside your own human DNA in the sample.
Micro measurements are nessessery because DNA is so small and microscopic and other measurements are simply too large (they are bigger than the DNA).
Some would be bacterial, fungal, viral, food residue, etc.
Alll I know is that nucleus acid is found n DNA but other than that i don't know .........sorrry
Made from other DNA
Another thing is to look for genetic damage or change in chromosome number which can lead to birth defects.
