Discovery of DNA Structure/ From Nucleotides to Double Helix/ Hindi-Urdu Biology Lecture

Описание: The discovery of the DNA structure is one of the greatest achievements in biology.
It was not the work of a single scientist, but the result of several key discoveries that were finally brought together by Watson and Crick in the form of the double helix model.

In this lecture, we explain the scientific evidence step by step, including:
• Friedrich Miescher and the discovery of nuclein
• DNA as a polymer
• Nucleotides as repeating units of DNA
• Structure of a nucleotide
• Role of phosphate group, deoxyribose sugar, and nitrogenous base
• How these discoveries led to the double helix model

This video is especially useful for O Level, A Level, FSC, and undergraduate biology students and is highly important for final examinations.
