DNA is basically a couple of molecules joined together by molecular bonding from atoms. in this case when you have one strand (one side from the stair case), you have the other starnd going on the opposite direction. They are united by hydrogen bonding which makes the stair to in a spirally fashion way One strand= one sid A DNA double helix consists of two spiral chains of deoxyribonucleic acid. The shape is similar to that of a spiral staircase. DNA is a nucleic acid composed of nitrogenous bases (adenine, cytosine, guanine, and thymine), a five-carbon sugar (deoxyribose), and phosphate molecules
The DNA shape is popularly referred to as a spiral stairway, twisted ladder though mainly as a double helix. This is because it mimics a ladder when turned straight and unspiralled. The steps of the ladders are known as rungs and are 4 in particular. These four rungs are chemically bonded together and are called nucleotides or nitrogen bases The shape of DNA resembles that of a spiral staircase. In this double helical shape, the sides of the staircase are formed by strands of deoxyribose sugar and phosphate molecules. The stair steps are formed by the nitrogenous bases. The twisted double helix shape of DNA helps to make this biological molecule more compact
The DNA molecule is shaped like a twisted ladder. Earlier work had shown that DNA is composed of building blocks called nucleotides consisting of a deoxyribose sugar, a phosphate group, and one of four nitrogen bases — adenine (A), thymine (T), guanine (G), and cytosine (C). Phosphates and sugars of adjacent nucleotides link to form a long. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G), or thymine (T)

The four bases that make up all of our DNA are adenine (A), guanine (G), cytosine (C), and thymine (T). Scientists have recently taken interest in studying structures very similar to DNA, called XNAs
A spiral structure is the most space efficient structure to avoid water. The bases of the DNA (Adenine, Thymine, Guanine, Cytosine) are hydrophobic (water repellent) in nature, meaning that they, and therefore the DNA, will not be able to survive. 24) In the comparison of a DNA molecule to a twisted ladder, the rungs (footholds) of the ladder are A) the backbones of the molecule.B) deoxyribose linked to phosphate.C) nitrogenous bases linked together. D) deoxyribose linked to sulfate.E) nitrogenous bases linked to phosphate. Answer: C 24) Chapter Section: 12.2Learning Outcome: 12.2 5 The subunits of DNA are nucleotides. Nucleotides are made up of a sugar, phosphate, and a base. There are only 4 bases possible in DNA and they make up the rungs or steps of the twisted staircase shape of DNA. These rungs will always be two bases paired like this: adenine and thymine & guanine and cytosine
Two DNA molecules are wrapped around one another in a shape resembling a spiral staircase or a twisted ladder. The sides of the ladder are made up of sugars and phosphate molecules. The rungs of the ladder contain information. The four nucleotides - the rungs, called adenine, guanine, thymine, and cytosine - form patterns The rungs of the twisted ladder are made up of the two bases attached together with a weak chemical bond, called a hydrogen bonds. Two bases hydrogen bonded together is called a base pair . The ladder twists along its length, hence the double helix description, which means a double spiral DNA - The ultimate chemical photocopier So, what is DNA? Put very simply, it is a giant molecule consisting of a spiral staircase with sides made of sugars and phosphates, on which the rungs are assembled from four simple purine and pyrimidine nucleotides Adenine (A) and Thymine (T) or Cytosine (C) and Guanine (G) The shape of the DNA is double helix. (Think of a spiral staircase with two sides). The sides are made up of sugar-phosphate-sugar-phosphate etc. In case of the DNA it is deoxyribose-phosphate-deoxyribose-phosphate, etc. The rungs (steps) are made up of two bases joined by weak hydrogen bonds with strict base pairing Pairs of Nucleotide bases make up the steps or rungs of a DNA molecule. There are just very slightly more than ten nucleotide base pairs per [360 degree] turn of the Dna double helix 'strand'
Most staircases are shown to be straight up and down, however, their is a trend of spiral staircases. Spiral staircases were first seen in the 1800's in Greek temples The mathematical ideas the Fibonacci sequence leads to, such as the golden ratio, spirals and self- similar curves, have long been appreciated for their charm and beauty, but no one can really explain why they are echoed so clearly in the world of art and nature. The story began in Pisa, Italy in the year 1202 Staircase parts . Staircases may be all sorts sizes and arrangements (with or without landings etc) to suit different properties but the main parts which go up to make any stair case are fairly common. A typical staircase is illustrated below with the main parts identified with more detailed definitions of each below DNA (Deoxyribonucleic Acid) structure (what it looks like)-Double helix-spiral staircase-twisted ladder.

A Stair is a system of steps by which people and objects may pass from one level of a building to another. A stair is to be designed to span a large vertical distance by dividing it into smaller vertical distances, called steps. Some of the functional requirements of staircases are Stair Calculator. The stair calculator is used for calculating stair rise and run, stair angle, stringer length, step height, tread depth, and the number of steps required for a given run of stairs. For convenience and flexibility, this stair stringer calculator comes in two forms, the automatic and manual.Click on the [?] icons to determine the best calculator to use for your stairs The golden spiral is commonly found in nature and you can draw it using elements of the Fibonacci sequence. You'll need a piece of graph paper, a compass, a pencil, and an eraser. First, draw squares in a counterclockwise pattern on the piece of paper using the Fibonacci sequence If DNA were thought of as a spiral staircase, the base pairs would be the steps. The width of each step is approximately the same size, since a base pair always consists of one pyrimidine and one purine. The strands of DNA run anti-parallel, or in opposite directions: the 5' end of one strand is paired with the 3' end of the other
suggested a model . for the structure of DNA. Two nucleotide strands wrap around each other to form a double spiral (spiral staircase) The nitrogen bases form the center rungs of DNA. The outside, sugar-phosphate backbone, is made of alternating phosphates and sugars held together by covalent bonds Steps to DNA Replication. 1. DNA is. The nitrogenous bases are stacked in the interior, like the steps of a staircase, and these bases pair; the pairs are bound to each other by hydrogen bonds. The bases pair in such a way that the distance between the backbones of the two strands is the same all along the molecule In fact, until the 1950s, the structure of DNA remained a mystery. In this article, we'll briefly explore how the double-helical structure of DNA was discovered through the work of James Watson, Francis Crick, Rosalind Franklin, and other researchers. Then, we'll take a look at the properties of the double helix itself Small compounds that interact noncovalently with DNA can bind to the minor or major groove between the two walls of the DNA helix, via intercalation between two planar rungs of the base pase staircase (Figure 1) or covalently as a result of DNA alkylation. Most of the DNA unwinding compounds with well-defined binding modes belong to the. I could see him going up the center spiral staircase. There were left and right hallways also past the doors. I followed I..R. up the staircase behind two girls. The stairs were flat at the bottom, but then took on more and more angular pattern as they went up and there was a center railing too. Each stair had 3 rectangular rungs together
posed that DNA consists of two chains that twine around each other like the two handrails of a right-handed spiral staircase. (Point the thumb of your right hand up; the curve of your fingers tells you the direction the spiral takes as it climbs up.) Second, joining the two chains are a series of steps that run perpendicular to the handrails. DNA (deoxyribonucleic acid) is a double-stranded molecule that is twisted into a helix like a spiral staircase. Each strand is comprised of a sugar-phosphate backbone and numerous base chemicals attached in pairs. The four bases that make up the stairs in the spiraling staircase are adenine (A), thymine (T), cytosine (C) and guanine (G) The Double Helix Spiral Ladder. Both strands are half of the double helix. Yet, the leading strand can be seen as the rigid backbone. The broken pieces of the lagging strand are the steps that spiral around. Lagging Strand (Humanity) The Bad Twin. This strand of DNA is oriented in the 3' to 5' direction and is synthesized in small pieces.
Bases attached in pairs in the center of the molecule. Sugars and phosphates on the outside, forming a backbone.. If you were to untwist a DNA double helix and lay it flat, it would look a lot like a ladder. The bases are attached to each other in the center to make the rungs, and the sugars are joined together by phosphates to form the.
