In 1882, Walter Fleming, a German biologist, first stained chromosomes to observe them more clearly under a microscope. Through this, he was able to describe the entire process of mitosis for the first time.
Fleming's work laid the foundation for our understanding of cell division, specifically how chromosomes are duplicated and distributed into daughter cells during mitosis.
Information Booster:
- He used a special stain called aniline dye to visualize chromosomes under the microscope.
- Fleming’s observations included the identification of chromosome movement during various stages of mitosis, such as prophase, metaphase, anaphase, and telophase.
- His work greatly advanced the understanding of genetic inheritance and cell biology.
Additional Knowledge:
- 1901: This year is significant for Emil Fischer, who was awarded the Nobel Prize in Chemistry for his work on the chemistry of sugars.
- 1956: This year is notable for the discovery of the chromosome number in humans, which was identified as 46 chromosomes.
