Analyzing data from other scientists and their own research D. Pure luck 相关知识点: 试题来源: 解析 C。解析:沃森和克里克发现DNA的双螺旋结构主要是基于分析其他科学家的数据以及他们自己的研究。选项A仅他们自己的实验室实验不准确,因为也参考了别人的数据;选项B仅理论计算不全面;选项D纯靠运气是错误的。
James Watson and Francis Crick are famous for their discovery of the double - helix structure of DNA. How did they achieve this discovery? A. By working independently without any communication. B. By stealing the results from other scientists. C. By collaborating closely and using data from ...
DNA is the fundamental biomolecule required for correct cell functioning and, until very recently, it was associated with the double helix structure discovered over 70 years ago by Crick, Watson, and Franklin. However, other DNA structures and conformations such as G-quadruplex...
In biology, "double helix" is a term used to describe the structure ofDNA. A DNA double helix consists of two spiral chains of deoxyribonucleic acid. The shape is similar to that of a spiral staircase. DNA is anucleic acidcomposed of nitrogenous bases (adenine, cytosine, guanine, and thymi...
