WebApr 9, 2024 · 3.1: Synthesis of Biological Macromolecules. Biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. WebQ- Summarise Avery's experiment in your own words. Ans- In 1944 Oswald Avery , Colin MacLeod, Maclin McCarty worked to determine the biochemical nature of 'transforming principle ' in Griffith's experiment. -They purified biochemicals (protein,DNA , RNA etc) from the heat killed S cells to see which of them transform live R cells into S cells.

Webtransformation, in biology, one of several processes by which genetic material in the form of “naked” deoxyribonucleic acid (DNA) is transferred between microbial cells. Its discovery and elucidation constitutes one of the significant cornerstones of molecular genetics. The term also refers to the change in an animal cell invaded by a tumour-inducing virus.
Griffith's experiment, reported in 1928 by Frederick Griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. Griffith's findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that communicated this genetic information.
