MOLECULAR BASIS OF INHERITANCE. NCERT Based & Simplified 1. Finding out the chemical responsible for Mendelian inheritance (factor), its structure,& How it works is MOLECULAR BASIS OF INHERITANCE. 2. DNA act as genetic material in all cellular organism either it is prokaryotic or eukaryotic. o RNA ACT AS GENETIC MATERIAL ONLY IN SOME VIRUSES. o RNA also act as messenger ,adaptor & structural RNA. o RNA also act as enzyme molecule(Ribozyme) @ RNA World Hypothesis 3. THE DNA ●Polymer of Nucleotide -->POLYNUCLEOTIDE ●The length of DNA is expressed in base pair (bp) ●Specific for particular organism. ●Bp is number of nucleotide pairs in DNA ●Bacteriophage -Φ174 5386 nucleotides. ●Bacteriophage -->48502 bp ●E.coli --> 4.6x106 bp ●Human -->3.3 x109 bp in haploid cell. 4. BUILDING BLOCK OF NUCLEIC ACID and NUCLEOTIDE o A nucleotide has three component -a nitrogenous base (either purine or pyrimidine) ,deoxyribose pentose sugar...
