In this video you will get detailed description about DNA its structure and function-DNA stands for deoxyribonucleic acid it is a type of nucleic acid which are present in the nucleus of the cell in the form of chromosome in which the DNA are condensed with dna-binding proteins. For the first time DNA in the nucleus was identified by Frederick Miescher in 1869 he named it as nuclein.
DNA basically carries genetic information of most of the living organisms.
DNA molecule is a double helical structure that wind around each other like a twisted that wind around each other like a twisted ladder. Deoxyribonucleic acid is a polymer of deoxyribonucleotide-nucleotides has three components the phosphate, the sugar, and the nitrogenous bases- NITROGENOUS BASES ITS STRUCTURE watch this :   https://youtu.be/5rJ0stnR4SA
The double helical model for the structure of DNA was first time proposed by Francis Crick and James Watson based on the observation of Wilkin and Franklin x-ray diffraction data and Erwin chargaff who states that for a double-stranded DNA The ratios between adenine and thymine and guanine and cytosine are constant in equal ones.
In this video you will get the characteristic features of double helix structure of DNA as well as its functions.
