Key Points
- DNA was first recognized and identified by the Swiss biologist, Johannes Friedrich Miescher in 1869 during his research on white blood cells.
- DNA: DNA is a double helical long polymer of deoxyribonucleotides. The length of DNA is usually defined as a number of nucleotides (or a pair of nucleotides referred to as base pairs) present in it. This also is the characteristic of an organism.
- DNA contains a sugar-phosphate backbone, and the nucleotide bases (guanine, cytosine, adenine, and thymine).
- The coding segment of DNA is called the exon. A segment of DNA within a gene that encodes a sequence ultimately translated into a protein product.
- So, DNA is a polymer of nucleotide bases.
