DNA : DNA is the genetic material of organisms. It contains the genetic information coded within itself . And genetic information is passed onto over generations. Also DNA provides template for formation of RNA and also replicates itself when cell gets divided. DNA is composed of purines and pyrimidines connected through hydrogen bonds on a sugar phosphate backbone. These bases form codon for protein synthesis. RNA : RNA is ribonucleic acid which differs from DNA in sugar composition and in RNA thymine is replaced by uracil in RNA. RNA is of three types . mRNA which js useful for formation of Protein . rRNA OR RIBOSOMAL RNA is useful for ribosomes. and tRNA or Transfer RNA is important component of protein synthesis. So RNA is the key component of proteins in the cell. PROTEINS: Proteins we can say is one of the building blocks of cells in an organism. All enzymes required for physiological processes are proteinaceous in nature. So they are required for every minor processes of an organisms. CARBOHYDRATES : Carbohydrates are also one of the most important biological macro molecule. Several sugars are involved in energy generation in the cell. So carbohydrates basically are involved in generation of energy in the cell. ATP is produce by sugar metabolism only. LIPIDS : Lipids are also source of energy in cell and equally important biological macromolecule for teh cell. Stored lipids in the cell provides energy and from from lipids various metabolic pathways are important. BUILDING BLOCKS DNA and RNA : Nitrogenous bases Proteins : Amino acids Carbohydreate: Monosaccharide LIPIDS : Fatty acids. Solution DNA : DNA is the genetic material of organisms.
