What are the constituents of DNA and RNA?

Constituents of DNA are deoxyribonucleotides. It consists of a pentose sugar (deoxyribose), nitrogenous base (Adenine/Guanine/Thyamine/Cytosine) and a Phosphate (PO4 3- or simply P) group. read more

DNA, along with RNA and proteins, is one of the three major macromolecules that are essential for life. Most of the DNA is located in the nucleus, although a small amount can be found in mitochondria (mitochondrial DNA). read more

In double-helical RNA, the helices and the complementary base pairs are arranged in much the same manner as in A-DNA. Synthesis of RNA: Except perhaps in the case of the reproduction of cer­tain RNA viruses, the synthesis of RNA appears ‘to be directed by DNA and is called tran­scription. read more

DNA is a long molecule composed of two chains of smaller molecules called nucleotides, each which contain a region of nitrogen called the nitrogenous base, a carbon-based sugar molecule called deoxyribose and a region of phosphorus called the phosphate group. read more
