Biomolecules — Chemistry STD 12 Science — Question

→Every generation of each and every species resembles its ancestors in many ways.
→These characteristics transmitted from one generation to the next generation.
→It has been observed that nucleus of a living cell is responsible for this transmission of inherent characters also called heredity.
→The particles in nucleus of the cell, responsible for heredity are called chromosomes which are made up of proteins and another type of biomolecules called nucleic acids.
→These are mainly of two types, the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
→Nucleic acids are long chain polymers of nucleotides, so they are also called Polynucleotides.
