DNA â DeoxyriboNucleic Acid In this way a DNA molecule is similar in structure to a ladder in which the sugar and phosphate groups make the uprights and the nitrogen base groups the rungs. There are four types of nitrogen bases or base groups. 1  Adenine (A). 2  Thyamine (T).3  Cytosine (C). 4  Guanine (G).he nucleotides in the DNA molecule are linked in series from one phosphate, to the next sugar, to the next phosphate and so on. The DNA molecule can be considered as a ladder with the phosphate and the sugar molecules making up the uprights and the bases making up the rungs.

If DNA is a ladder, what are the uprights (sides) made of? Report Abuse. The structure of DNA is a double helix, much like a ladder that is twisted into a spiral shape. The nucleotide bases (A, T, C, G) that make up your genetic code are found in pairs in the middle of the helix.he base pairs that make up the rungs of the ladder are attached to the sugars in the sugar-phosphate chains that form the uprights of the ladder.

- A molecule of DNA is double-stranded. The molecule has the shape of a double helix, typically right handed (B form DNA).The DNA molecule consists of two complementary strands oriented in an antiparallel fashion. Each strand is composed of nucleotides.he twisted ladder metaphorA DNA molecule is often likened to a spiral (or twisted) ladder. In this analogy, the rungs of the ladder are the base pairs (A-T and G-C). The sides of the ladder are the sugar-phosphate backbones of the two strands. This refers to B form DNA.

The Structure of DNA In this model of a very short section of DNA you can see how the A-T and C-G base pairs make up the rungs of the ladder and the sugars and phosphates make up the two long strands.hese two models shows how all the atoms of the sugars, phosphates and nitrogenous bases fit together to make the spiral staircase or twisted ladder shape first suggested by the x-ray diffraction pictures of DNA taken by Rosalind Franklin and Maurice Wilkins.

- The rungs of the ladder are pairs of 4 types of nitrogen bases (thymines, adenines, guanines, cytosines). ---. The pairs are guanine and cytosine (G-C), or adenine and thymine (A-T). The rungs of the dna ladder are made of alternating sugars and phosophate groups. The uprights are called the backbone and is made up of ribose (a pentose sugar) and phosphate. The rungs are the bases that are the actual coding bit of DNA. These are c … arbon and nitrogen-based molecules that attach to the backbone.

- So, DNA is like a twisted ladder, where the sugar and phosphate are the rails, and the base pairs are the rungs. The rails run in opposite orientation to each other. The nucleotide rungs are complementary to each other. Wherever there is an A on one strand, there is a T in the same position on the other strand.

- They showed that alternating deoxyribose and phosphate molecules form the twisted uprights of the DNA ladder. The rungs of the ladder are formed by complementary pairs of nitrogen bases — A always paired with T and G always paired with C. DNA and proteins are key molecules of the cell nucleus. One gene makes one protein. A gene is made of DNA. Bacteria and viruses have DNA too. The DNA molecule is shaped like a twisted ladder. A half DNA ladder is a template for copying the whole. RNA is an intermediary between DNA and protein. DNA words are three letters long. A gene is a discrete sequence of DNA nucleotides. The RNA message is sometimes edited.

deoxyribonucleic acid / DNA The rungs of the ladder are pairs of units between A and T or between C and G. These pairs are called base pairs and they connect the two sugar-phosphate backbones through interactions called hydrogen bonds. In cells, the DNA helix is often overwound, causing a phenomenon known as supercoiling.

- A DNA ladder usually contains a set of known DNA fragments with different sizes in base pairs (bp) or kilo bases (kb). These DNA fragments are separated and visualized as DNA bands on a gel. These separated DNA bands together look like a ladder on the gel (see pictures below) and therefore it is called DNA ladder.

What is the structure of a DNA molecule? Z form DNA is found in living organisms, but is a left handed helix, meaning it twists in the opposite direction. Unlike A and B form DNA, the major and minor grooves have very similar sizes in Z form DNA. The twisted ladder metaphorA DNA molecule is often likened to a spiral (or twisted) ladder.In this analogy, the rungs of the ladder are the base pairs (A-T and G-C). The sides of the ladder are the sugar-phosphate backbones of the two strands.This refers to B form DNA.ach strand is composed of nucleotides. A nucleotide consists of a base (a purine or pyrimidine), a sugar (between the other two components) named deoxyribose, and a phosphate group. Nucleotides are linked to each other via phosphodiester bonds, forming a sugar-phosphate backbone to each strand.

- Make a model DNA strand Summary A strand of DNA looks like a ladder that has been twisted into a corkscrew. Just like a ladder, a DNA strand has two rails running parallel to each other and rungs that connect the rails. The rails of the DNA strand are made up of deoxyribose (a sugar) and phosphoric acid.he four bases that make up DNA are Adenine, Thymine, Cytosine, and Guanine. These bases are abbreviated as A, T, C, and G. Each rung of a DNA strand contains two bases that are paired together. Each base has a specific partner that it pairs with. Adenine always pairs with Thymine and Cytosine always pairs with Guanine.

How DNA Works The nitrogenous bases point inward on the ladder and form pairs with bases on the other side, like rungs. Each base pair is formed from two complementary nucleotides (purine with pyrimidine) bound together by hydrogen bonds. The base pairs in DNA are adenine with thymine and cytosine with guanine. DNA has a spiral staircase-like structure. The steps are formed by the nitrogen bases of the nucleotides where adenine pairs with thymine and cytosine with guanine.

- Upon looking at our model, everyone — including Maurice and Rosalind — agreed that we had the right DNA structure. So, DNA is like a twisted ladder, where the sugar and phosphate are the rails, and the base pairs are the rungs. The rails run in opposite orientation to each other. The nucleotide rungs are complementary to each other. Wherever there is an A on one strand, there is a T in the same position on the other strand.

How DNA Works DNA had two sides, or strands, and that these strands were twisted together like a twisted ladder -- the double helix. The sides of the ladder comprise the sugar-phosphate portions of adjacent nucleotides bonded together.
