Basic structure of DNA or deoxyribonucleic acid: A nucleotide is the basic of polynucleotide chain of DNA and each nucleotide is composed of three components - i) a nitrogenous base, ii) a pentose sugar and iii)
Phosphate is an integral part of the molecular backbone of DNA and RNA, constituting the linkage by which the monomeric units are connected. The phosphodiesters in DNA and RNA have distinct stabilitydoi:10.1007/s40828-017-0046-8MüllerSabine...
DNA is composed of deoxyribonucleotides. RNA (which is covered in other modules) is composed of ribonucleotides . Therefore, the DNA nucleotide (Fig. 2.1 ) is composed of a 5-carbon sugar (called deoxyribose), a phosphate group, and a nitrogenous base (nitrogen-containing structure). Note ...
DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytos...
Finally, the purity check regarding the A260/230 ratio is significantly lower than the expected 1.8 for …show more content… a. Salt and ethanol were essential in the precipitation DNA isolation process to create a counter ion force great enough to attract the negatively charged phosphate ions ...
What is the purpose of DNA replication? Why is DNA replication necessary to life? Why is the deoxyribose so important in DNA and why is the phosphate at the 5' end crucial for DNA replication? What is the role of DNA gyrase? Why is telomerase important for DNA replication? Why are prote...

(a) (i) List the components of a nucleotide.[1](ii) Explain what is meant by four different nucleotides.[1](b) Suggest why the brief heat treatment separates the two strands of the DNA double helix.[2](c) Suggest why DNA synthesis takes place in opposite directions on the two separat...
What is methylation in the body? When optimal methylation occurs, it has a significant positive impact on many biochemical reactions in the body that regulate the activity of the cardiovascular, neurological, reproductive, and detoxification systems, including those relating to: DNA production Neurotransm...
Thus, a DNA molecule is like a ladder that twists like a corkscrew, with the sugar and phosphate acting as the side rails and the base pairs acting as the rungs. Where Do We Find DNA? DNA is an extremely long molecule, so long that if all the DNA in a human was uncoiled and plac...
