d. It holds the cell in its proper position.
Answer:
Explanation:
Several scientists have made significant contributions to our current understanding of genetics. Here are a few examples:
1. Gregor Mendel: Mendel is often referred to as the "father of genetics." In the 19th century, he conducted groundbreaking experiments with pea plants and discovered fundamental principles of inheritance. His work laid the foundation for our understanding of how traits are passed down from one generation to another.
2. James Watson and Francis Crick: In the 20th century, Watson and Crick, along with Maurice Wilkins, elucidated the structure of DNA. Their discovery of the double helix structure in 1953 revolutionized our understanding of how genetic information is stored and transmitted. This laid the groundwork for modern molecular genetics.
3. Rosalind Franklin: Although often overshadowed, Franklin played a critical role in the discovery of DNA's structure. Her X-ray crystallography images provided crucial evidence that helped Watson and Crick develop their model. Franklin's work contributed to our understanding of DNA's physical properties and its role in inheritance.
4. Barbara McClintock: McClintock's research on corn plants in the mid-20th century revealed the existence of "jumping genes" or transposable elements. Her findings challenged the traditional view of genes as fixed entities and highlighted the dynamic nature of genetic material. McClintock's work earned her the Nobel Prize in Physiology or Medicine in 1983.
These scientists, along with many others, have made significant contributions to our understanding of genetics. Their discoveries have paved the way for further advancements in the field, leading to breakthroughs in areas such as genetic engineering, gene therapy, and personalized medicine.
