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) a phosphate group. Nitrogen base is attached to the pentose sugar by an N-gl...
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 the 5′-carbon (at the top) and the ...
What is the bond between a phosphate group and the ribose sugar group in RNA called?RNA:RNA is a type of nucleic acid in life that is typically single-stranded and transiently made within the cell. There are multiple types of RNA, with the main ones being: ...
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...
What is phosphate? where does it come from? why is it so important for the human body? and how ICL comes into play.
they connect. This variation in stability can be explained by the 2′-hydroxyl group that is available in RNA, but not in DNA, acting as a neighbor group nucleophile attacking the scissile phosphate. This reaction in nature is supported by enzymes or ribozymes to accelerate the rate of reacti...

· A sugar - In DNA, the sugar group is composed of a 5-carbon sugar deoxyribose· A phosphate - The phosphate is attached to the fifth (5th) carbon of the sugar· The base - The base (nitrogenous base) is attached to the first carbon of the sugar. The bases are divided into two...
