Detailed explanation-1: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.
Detailed explanation-2: -The liver is the major organ of de novo synthesis of all four nucleotides. De novo synthesis of pyrimidines and purines follows two different pathways.
Detailed explanation-3: -DNA molecules are composed of four nucleotides, and these nucleotides are linked together much like the words in a sentence. Together, all of the DNA “sentences” within a cell contain the instructions for building the proteins and other molecules that the cell needs to carry out its daily work.
Detailed explanation-4: -Nucleosides are the structural subunit of nucleic acids such as DNA and RNA.
