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。
On the other hand, the AATT segments in oligonucleotide double helices tend to be propeller twisted, and the AT domains conform to a structure similar to that of Levitt and Dickerson models. These studies indicate that under solution conditions the DNA double helix, depending upon sequence, can...
the later work of Watson and Crick, but Chargaff himself could not imagine the explanation of these relationships--specifically, that A bound to T and C bound to G within the molecular structure of DNA (Figure 2). Figure 2: What is Chargaff's rule?
James D. Watson is credited with the discovery of the double-helix structure of DNA along with Francis Crick. Watson received a 1962 Nobel Prize and went on to do work in cancer research and mapping the human genome. He later came under fire for several controversial remarks on subjects rang...

This section provides a quick introduction of the primary structure of a DNA (Deoxyribonucleic Acid), which is a double helix formed by the backbones of two complementary DNA sequences paired together.
Franklin’s crucial work in the discovery of the structure of DNA has ensured her own scientific immortality. Without her passion to research we may not have made the huge strides in science, medicine, and agriculture that we have witnessed over the last 50 years. The knowledge of DNA, cells...
DNA’s double helix structure could only be detected by scattering X-Rays off atoms in DNA with a technique known as X-Ray crystallography. Di Fabrizio’s method uses a scanning electron microscope, which, as its name suggests, involves scanning the tiny subject with a focused beam of electro...
Which enzyme is responsible for breaking the H-bond in the double-helix structure of DNA? View Solution (a) What is denaturation of proteins? (b) What type of bonds hold a DNA double helix together? (c) Which enzyme is present in saliva? What is its function?
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...
