1.The numbers refer to the position of the carbon atom in the deoxyribose molecule at the end of the strand to which the next phosphate molecule in the DNA chain attaches. 2.DNA contains deoxyribose and thymine, while RNA contains ribose and uracil. ...
All nucleotides have three parts, a sugar, a phosphate, and a base. The sugar can be either deoxyribose or ribose. The phosphate group is one phosphate atom bound to four oxygen atoms and the bases can be either thymine, uracil, adenine, guanine, or cytosine. Answer and Explanation: Beco...
Deoxyribosenucleic acid (DNA) was first discovered in 1869 by the Swiss scientist, Friedrich Miescher. Nucleic acids are biopolymers comprised of nucleotide monomers that are composed of three moieties, a five-carbon sugar, a phosphate group, and a nitrogenous base. DNA contains deoxyribose as the...
In conclusion, RNA is a polymer with a ribose and phosphate backbone and 4 different bases: adenine, cytosine, guanine, and uracil, whereas DNA is a long polymer with a deoxyribose and phosphate backbone and four different bases: adenine, cytosine, guanine, and thymine. READ THIS NEXT: Spirit...
nucleobases (cytosine [C], guanine [G], adenine [A] or thymine [T]), a sugar calleddeoxyribose, and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds (known as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate ...

Although multifunctional DNA glycosylases can cleave AP sites, apurinic/apyrimidinic endonuclease 1 (APE1) processes most AP sites via hydrolysis of the phosphate bond 5′ to the AP site creating a single strand break with a 3′-OH group and a 5′ terminal 2′-deoxyribose phosphate (dRP) ...
DNA comprises twopolynucleotidestrands twisted around each other in the form of a double helix (Figure 2.1). Each strand has asugar phosphatebackbone linked from the 5′ and 3′ carbon atoms ofdeoxyribose. At the end of a strand is either a 5′ phosphate group (5′ end) or a 3′ phosp...

Previous experiments with thermally labile molecules such as D-ribose-5-phosphate [61] have already demonstrated that this method may also be applicable for DEA experiments. For BrSU, thermal decomposition did not play a role, and we observed strong decomposition of the molecule upon attachment of...
