Study Notes

Structural Biology is the study of biological macromolecules using various imaging and spectroscopic techniques to understand their functions in three dimensions.
The course aims to provide a historical perspective on how biotechnology has evolved, starting from the development of Biology to understanding biological macromolecules and their structures.
Structural Biology involves studying how molecules interact, such as DNA-protein interactions, membrane construction, protein synthesis machinery, protein-solvent interactions, and protein conformational changes.
Enzymes play a crucial role in biological processes, and understanding their conformational changes helps in regulating functions to prevent diseases.
Structural studies have helped researchers understand how different molecules in cells work together, leading to new treatments for diseases.
The application of Structural Biology extends to understanding evolution through changes in domain structures and confirming organization.
The course emphasizes the importance of visualizing molecules in high resolution to comprehend biological processes accurately.- Empedocles introduced the concept of the four elements - water, air, fire, and earth.
Hippocrates and his school focused on the idea of living bodies being made up of four humours: blood, phlegm, yellow bile, and black bile.
Initial observations and hypotheses were made by ancient civilizations, but the lack of proper tools hindered scientific investigations.
The microscope was invented in the 16th century by Hans Jensen and Zacharias, leading to advancements in scientific research.
Antonie van Leeuwenhoek made significant progress by developing a real microscope with a magnification of up to 270X.
Robert Hooke described cells under a microscope in 1665, leading to the cell theory.
Technical improvements in microscopy included addressing chromatic aberration to enhance resolution.
German botanist Mathew Jacob Schleiden and zoologist Theodor Schwann contributed to the cell theory by postulating that all organisms are composed of cells.
The cell theory postulates that all living organisms are made of cells, cells arise from pre-existing cells, and genes are located within the cell nucleus.
Charles Darwin's theory of natural selection and Gregor Mendel's laws of heredity were significant advancements in understanding genetics.
The discovery of DNA as the genetic material was confirmed through experiments by Avery, MacLeod, McCarty, Hershey, and Chase.
The interdisciplinary field of molecular biology emerged as biology started focusing on molecular interactions and genetic properties.
