Detailed Solution
Download Solution PDFThe correct answer is Triple helical structure of collagen.
Key Points
- G.N. Ramachandran is renowned for his significant contributions to biochemistry, particularly for elucidating the triple helical structure of collagen.
- His work established that collagen, a key structural protein in connective tissues, consists of three polypeptide chains that form a right-handed triple helix.
- The discovery of collagen's structure has implications for medicine, particularly in understanding diseases related to connective tissues.
- Ramachandran's work has earned him recognition as a pioneer in structural biology, influencing subsequent research in the field.
Additional Information
- Fluid Mosaic Model of a Cell:
- Proposed by Singer and Nicolson in 1972, this model describes the cell membrane as a dynamic and flexible structure with a mosaic of various proteins floating in or on the fluid lipid bilayer.
- It highlights the importance of membrane proteins in functions such as signaling, transport, and maintaining cell shape.
- Plasma Membrane:
- The plasma membrane is the outer boundary of the cell that separates its interior from the external environment.
- Composed of a lipid bilayer with embedded proteins, it regulates the movement of substances in and out of the cell, playing a crucial role in cell communication and homeostasis.
- Golgi Bodies:
- Also known as the Golgi apparatus, these organelles are involved in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.
- Discovered by Camillo Golgi in 1898, the Golgi apparatus is essential for processing molecules synthesized in the endoplasmic reticulum.
