How do you use deoxyribose in a sentence?
Deoxyribose is a sugar component found in the structure of DNA molecules. For example, "Deoxyribose is a key building block in the double helix structure of DNA, providing stability and support for the genetic information encoded within."
Is deoxyribose a simple sugar that is part of RNA?
Deoxyribose is more stable! If you look at the structure of ribose in RNA you see that it has OH Groups at C2 and C3, both of which are reactive. We need the one at C3 to react with the next phosphate, but C2 can only lead to crosslinking; damaging the structure. If this happens to RNA its not a big deal for we can always produce another strand. If its DNA its a serious mutation, so cells have to use deoxyribose for DNA for it doesnt have a free OH at C2. Deoxyribose is produced from ribose. Using deoxyribose for RNA is an unnecessary waste of energy; the crosslinking doesnt happen that often anyway.

What substances would not be found in RNA?
To understand what substances do not exist in RNA, it is important to first understand what substances ARE in RNA. RNA, like DNA, is a polymer. It is made up of many repeating units of molecules, over and over again. RNA is a phosphosugar, meaning that it is primarily made up of molecules of phosphorus and sugars over and over again. In the case of RNA, the sugar in question is the "ribose" sugar. Ribose sugar in RNA is almost indistinguishable from its DNA counter part "deoxyribose" sugar. What separates ribose from deoxyribose, is the presence of an oxygen molecule on the sugar's second carbon, which deoxyribose lacks. The phosphorus and the ribose alternate repeatedly, over and over to form the backbone of the RNA molecule. In addition to the backbone of RNA, 4 nitrogenous bases are attached to each of the ribose sugars on the backbone. These 4 bases are adenine, cytosine, guanine, and uracil. Particular importance is placed on the presence of uracil in RNA, because uracil also happens to be absent in DNA. Instead, DNA molecules use the base thymine. This too is a distinguishing factor between DNA and RNA. In knowing this we can make the following important deductions as to what substances are NOT found in RNA: 1. Deoxyribose sugar is not found in RNA (only DNA) 2.Thymine is not found in RNA (only in DNA) 3. Essentially any substance that is not ribose sugar, phosphorus, or any of the RNA bases (A,G,C, and U), is not found traditionally, in RNA.
What is the use of DNA for protein synthesis?

Functional difference between RNA and DNA?
RNA is typically single-stranded while DNA is double-stranded. RNA contains the sugar ribose while DNA contains deoxyribose. RNA uses uracil as a base instead of thymine found in DNA. RNA is usually involved in protein synthesis and gene regulation, while DNA stores genetic information.
3 differences between RNA and DNA?
DNA has a deoxyribose sugar; RNA has ribose sugar. DNA is double stranded; RNA is single. DNA has adenine that pairs with thymine, guanine that pairs with cytosine; RNA has adenine that pairs with uracil, guanine that pairs with cytosine. DNA resides in the nucleus; RNA resides in both the nucleus and the cytoplasm (near ribosomes)
How do you use diphenyl amine to estimate DNA?
Diphenyle amine reacts with DNA and liberates inorganic ortho phoshate of Dna. amine group of diphenylamine is combined with DNA before the phosphate group is released from the sugar. By this action DNA solution gets dark blue color which was estimated by using spectrophotometer.
Does DNA contain ribosomes?
No, ribosomes do not contain DNA. DNA is found within the nucleus, mitochondria, and chloroplasts of a cell, and nowhere else.Ribosomes contain RNA and proteins.
Difference from DNA and RNA?
1. DNA is composed of a deoxyribose sugar and a phosphate backbone where as RNA is composed of ribose sugar and the phosphate backbone. 2. DNA uses Purines Adenine and Guanine and the Pyrimidines Cytosine and Thymine RNA uses the Purines Adenine and Guanine and the Pyrimidines Cytosine and Uracil, Uracil being the only difference between them here. 3. DNA takes the form of an anti-parallel double stranded helix whereas RNA has many more structural possibilities. These include single-strand (mRNA) or secondary structures (tRNA and other enzymatic RNA). 4. DNA cannot leave the nucleus and therefore needs RNA to transcribe it for its genetic information to be of use. 6. Ribose sugar on the RNA backbone makes it more reactive. RNA can serve as primitive enzymes. 7. There are many types of RNA defined based on function and structure. There include mRNA, tRNA, rRNA, snRNA, snoRNA, etc. Because of RNA's differences it can perform many other functions and take on many more unique shapes than DNA which is essential to tasks such as DNA and protein synthesis and can even combine with enzymes to perform far more tasks.
What are DNA and RNA have in common?
They are both nucleic acids. Regarding structure, DNA and RNA are similar because they are both built of nucleotides, structures consisting of one nucleobase, a sugar (ribose or deoxyribose respectively) and a phosphate group. For both of them, their function is mainly containing information in the form of code, using 4 different bases. They both use adenine, cytosine and guanine. The fourth base differs, DNA uses thymine while RNA uses uracil. More detail: Ribose has one more OH group than deoxyribose. This makes it more reactive, increasing mutation rates. Hence why RNA genomes (e.g. in certain viruses) cannot exceed a certain size without the error rate during copying running so high that the copies can hardly be called copies. DNA genomes are stabler and can grow to much larger sizes (other viruses and all organisms larger than them).
Why do you use dpa for estimation of DNA other than oricinol?
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
