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

Are DNA and RNA carbohydrates?
Yes, DNA and RNA have different sugar . DNA contains deoxyribose sugar whereas RNA consists of ribose sugar, which are completely different from each other.
What is happens during the s phase of the cell cycle?
DNA is replicated.
Why do investigators use DNA instead of other physical evidence?
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
What are the research tools that were used in the past and are use today to study DNA structure and function?
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
What part of the cell contains DNA apart from the nucleus?
The mitochondria contain their own DNA in plants and animals; and chloroplasts contain their own DNA in plants and other photosynthetic organisms. Both of these structures divide (almost like cells) inside the cells.*This is also evidence for the theory of endosymbiosis, in which early cells ate early prokarotic cells (bacteria) and gained new organelles.
What are the methods for estimation of DNA?
diphenylamine reagent
Do triplets have the same DNA?
No, but their DNA is closer to each other than other people.
What is extrachromosomal replicon?
+other than chromosomal DNA is known as extra chromosomal DNA like plasmids, mitochondria and chloroplast containing DNA.
Do animals other than humans have unique DNA?
Yes
Why is DNA evidence difficult to refute in court?
No two individuals, other than identical twins, have the same DNA.
How does using DNA compare with other older methods?
DNA analysis is a more exact science than the other older methods used to catch criminals. DNA can only belong to one person.
Can a virus be something other than DNA?
A virus doesn't have DNA, it 'high jacks' it from cells. They work by basically taking over other living cells so they can reproduce, so the need DNA to live but they don't have any- Thus they steel DNA from other living organisms.
Which organ cell in the cell other than nucleus contains DNA?
Centriole
Where is DNA located in Eukaryote cells other than the nucleus?
help answering
What is DNA in an uncondensed form?
An uncondensed DNA is called a chromatin. It is the material that makes up the chromosomes of organisms other than bacteria.
Why are micro measurements necessary when working with DNA?
Micro measurements are nessessery because DNA is so small and microscopic and other measurements are simply too large (they are bigger than the DNA).
What other type of DNA other than your own human you would find when extracting DNA from cheek cell?
Some would be bacterial, fungal, viral, food residue, etc.
