DNA as an acidic substance present in nucleus. The base pair are said to be complementary to each other. Each strand from a DNA
acts as a template for synthesis of a new strand. DNA is made of two polynucleotide chains, where the backbone is
constituted by sugar-nitrogenous bases . |
| DNA is made of two polynucleotide chains, where the backbone is constituted by sugar-nitrogenous bases . |
| DNA is made of two polynucleotide chains, where the backbone is constituted by sugar-phosphate, and the bases project inside .DNA as an acidic substance present in nucleus was first identified by Friedrich Meischer in 1869. He named it as ‘Nuclein’.Each strand from a DNA acts as a template for synthesis of a new strand , the two double stranded DNA (let us call them as daughter DNA) thus, produced would be identical to the parental DNA molecule . |
