What scientist figured out the three dimensional structure of DNA by using a model of metal and wood?
James Watson and Francis Crick are the scientists credited with discovering the three-dimensional structure of DNA using a model made of metal and wood in 1953. Their model revealed the double helix structure of DNA, which has since become a fundamental concept in Biology and genetics.

What is the composition of metal, and how does it differ from living organisms in terms of cellular structure?
Metal is composed of metallic elements like iron, copper, and aluminum, which have a crystalline structure. In contrast, living organisms are made up of cells that contain complex organic molecules like proteins and DNA, organized into specific structures for different functions. The cellular structure of living organisms is much more intricate and dynamic compared to the rigid crystalline structure of metals.
Role of edta in protein isolation?
Ethylene diamine tetraacetic acid (EDTA) is used in protein isolation to chelate and bind divalent metal ions, such as calcium and magnesium, which could potentially degrade the protein structure and function. By sequestering these metal ions, EDTA helps to stabilize the protein structure during the isolation process, preventing protein denaturation and maintaining its biological activity. Additionally, EDTA can also inhibit metal-dependent proteases, further protecting the integrity of the isolated proteins.
Is sodium and oxygen a metal or non-metal?
Do you breathe metal? Oxygen is a gas, not metal.
What are Metal joints are placed between concrete sections?
Metal joints, such as expansion joints or control joints, are often placed between concrete sections to allow for movement and prevent cracking. These joints help to accommodate the expansion and contraction of the concrete due to temperature changes, thereby reducing the likelihood of cracking and maintaining the structural integrity of the concrete pavement or structure.
What is metalloprotein?
Metalloprotein are those which contain metal ions such as iron, cobalt, nickel etc., these proteins are usually enzymes and co factors for enzymes and comes under the category of conjugated proteins in which the non-protein part (metal ion) is called as prosthetic group or conjugatin group.
Is the string a two dimensional or a three dimensional object?
Considering it mathematically string is nothing but a line... So it only has one dimension that is length.. considering it physically.. It is nothing but a metal ROD.. with a given Diameter so it has three degrees of freedom hence it is a 3D structure..
What are porous metals?
Porous metal is a metal structure which has a number of holes.It is a new metal material which has characteristics of both porous structure and metal.
The ions in solid sodium chloride are arranged in a structure called an?
The ions in solid sodium chloride are arranged in a structure called an ionic lattice or crystal lattice. This structure consists of alternating positive sodium ions and negative chloride ions arranged in a three-dimensional repeating pattern.
What type of crystalline solid can be found in metal atoms?
Metal atoms can form metallic crystals, where the atoms are arranged in a regular pattern called a metallic lattice. In this lattice, the metal atoms are closely packed together in a repeating three-dimensional structure, which gives metals their characteristic shiny appearance and good electrical conductivity.
What is the structure of lead metal?
Normally lead metal will have a cubic face centered lattice structure.
What kind of scientist studies metal?
A metallurgist is a scientist who specializes in the study of metals, their properties, and how they can be used in various applications. They may work to develop new metal alloys, improve metal production processes, or study the behavior of metals under different conditions.
What is a scientist looking at when he is using a microscope to view a crystalline structure?
One possible answer is he/she is looking at the crystal structure that forms in a metal lattice, or just metals. These crystals can vary in size by the processes of quenching, anealling and tempering, larger, moderate and smaller respectively. The crystal sizes can vary the properties of the metal, making it more ductile, harder, brittle, softer, etc.
What are the s-block hydrides with covalent polymeric structure are?
Some examples of s-block hydrides with covalent polymeric structures are lithium hydride (LiH) and sodium hydride (NaH). These compounds have a three-dimensional network of covalent bonds between the metal cation and the hydride anion, forming a polymeric structure.
Does dubnium have a crystal like structure?
As a metal dubnium has a crystalline structure but this structure is not known today.
Is chlorophyll a monosaccharide?
No it is not. It is a metal tetrapyrole structure.
What is the structure of an airplane?
Its metal coating and the skeleton
What is an archaeometallurgist?
An archaeometallurgist is a scientist who is an expert in archaeometallurgy - the prehistory of metal extraction and working.
