yesterday i posted a question about who discovered DNA and Ms Sue kindly helped me but im confused about who actually discovered DNA because there are four different names Friedrich Miescher,Rosalind Franklin,james D Watson and Francis Crick. my homework question is who discovered DNA .
i am very sorry Ms Sue if i sound ungrateful im not thanks for helping me:)
thankyou for your help !
No problem at all! I'm here to help clarify any confusion. The discovery of DNA is a complex story involving multiple scientists. Friedrich Miescher, a Swiss biochemist, is credited with isolating DNA for the first time in 1869. However, he didn't fully understand its significance or its role in heredity.
Fast forward to the mid-20th century, where Rosalind Franklin, an English chemist, conducted groundbreaking X-ray crystallography experiments that provided vital insights into the structure of DNA. Her work was crucial in the discovery of the now-famous double helix structure.
James D. Watson and Francis Crick, two scientists at the University of Cambridge, also made significant contributions. In 1953, they proposed a model for the structure of DNA based on Franklin's and other researchers' findings. Their model incorporated the crucial idea of complementary base pairing, which explained how DNA carries and transmits genetic information.
The combined efforts and discoveries of Miescher, Franklin, Watson, and Crick collectively led to our understanding of DNA. So, while the discovery of DNA involved multiple contributors, if your homework question asks about the discovery of DNA, James D. Watson and Francis Crick would be the most commonly recognized as the ones who proposed the double helix model and its significance in genetics.
It's important to note that scientific discoveries often involve the collaborative efforts of many researchers over time, and it's the combination of their work that brings us closer to the truth.
No problem at all! I'm here to help clarify things for you. The discovery of DNA is a complex topic, and it involves the contributions of multiple scientists. However, James D. Watson and Francis Crick are credited with the discovery of the double helix structure of DNA, which is known as the shape of DNA. Their research and model-building in the early 1950s based on various experimental data and especially the work of Rosalind Franklin were key in unraveling the structure of DNA. Before them, Friedrich Miescher discovered DNA in 1869, but at the time its significance was not fully understood.
So, to answer your homework question, you can say that James D. Watson and Francis Crick are credited with the discovery of the DNA double helix structure.
