What two scientists are credited with establishing the structure of dna.<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The two scientists credited with establishing the structure of DNA are James Watson and Francis Crick<\/strong><\/mark>. In 1953, they proposed the double helix model of DNA, which revolutionized our understanding of genetics.<\/p>\n\n\n\n Watson and Crick’s model emerged from the combination of their insights and the critical contributions of other scientists, particularly Rosalind Franklin and Maurice Wilkins. Franklin\u2019s X-ray diffraction images of DNA, especially the famous Photo 51, provided key evidence of the helical structure of the molecule. Her meticulous work demonstrated that DNA had a uniform diameter and was shaped like a twisted ladder. Wilkins, a colleague of Franklin\u2019s at King\u2019s College London, shared some of her data with Watson and Crick without her knowledge, which they later credited as pivotal in their discovery.<\/p>\n\n\n\n In their 1953 paper published in Nature<\/em>, Watson and Crick described DNA as a double helix composed of two strands that coil around each other. Each strand is made up of a backbone of sugar and phosphate groups, with nitrogenous bases (adenine, thymine, cytosine, and guanine) attached to the sugar. The bases on opposite strands pair specifically\u2014adenine with thymine and cytosine with guanine\u2014through hydrogen bonding. This base pairing is fundamental to the process of DNA replication and the transmission of genetic information.<\/p>\n\n\n\n Their model not only explained how genetic information is stored but also provided insights into how it is replicated and passed from one generation to the next. The discovery of the DNA structure was monumental, laying the foundation for molecular biology, genetics, and biotechnology, and it has had profound implications in fields ranging from medicine to forensic science. Watson and Crick were awarded the Nobel Prize in Physiology or Medicine in 1962, along with Wilkins, in recognition of their groundbreaking work.<\/p>\n","protected":false},"excerpt":{"rendered":" What two scientists are credited with establishing the structure of dna.
