Description:
In this video, we explain the Watson and Crick model of DNA, proposed in 1953, which revealed the famous double helix structure of DNA. James Watson and Francis Crick showed that DNA consists of two antiparallel polynucleotide strands twisted around each other like a spiral ladder. The strands are held together by hydrogen bonds between complementary nitrogenous bases—Adenine pairs with Thymine, and Guanine pairs with Cytosine.
The video covers the key features of the DNA structure, including the sugar-phosphate backbone, base pairing, and the importance of this model in explaining DNA replication and genetic inheritance. This discovery laid the foundation of modern molecular biology and genetics.
📚 Useful for Class 12 Biology, NEET, and other competitive exams.
