What forms the steps of a DNA molecule?
The DNA molecule consists of paired nucleotides that make each "rung" of the ladder. Each nucleotide is made up of a one of four nitrogenous bases (adenine, guanine, cytosine, or thymine), a five-carbon sugar (either ribose or 2'-deoxyribose), and a phosphate molecule.
In which year was DNA discovered?
DNA was discovered by a Swiss scientist, Friedrich Miescher, in 1869.In 1953 James Watson and Francis Crick proposed the double-helix structure for the molecule, and by 1966 the genetic code (i.e. which amino acids were coded for by which sequences of DNA bases, and what the remaining codons "meant", ) had been completely worked out.__________________________________________________________________________While examining the DNA molecule, Watson and Crick (1953), proposed a satisfactory model for the arrangement of these constituents. For this important contribution to science they were given the 1962 Nobel Prize. They hypothesized from X-ray analysis of the molecule that DNA consists of two strands, twisted in a spiral (or helix) shape. This shape resembles a twisted ladder with rungs between the two uprights. The "uprights" of this ladder are made entirely of alternating phosphate and sugar molecules. The rungs are composed only of the nitrogen bases, which are attached to the sugar. The phosphate-sugar-base is called a nucleotide. The base of the nucleotide from one "upright" of the ladder is paired with and bonded to the base of the nucleotide from the other side of the ladder, completing the rung between the two uprights. A nucleotide having adenine is always cross-paired with thymine, and one with cytosine is always bonded to guanine.
What is the difference between a base and a nucleotide?
A nucleotide is the sugar (in DNA is a deoxyribose in RNA it's ribose), phosphate group and 1 base. A base pair is the "rung in the ladder" for example in DNA it could be adenine + thymine or guanine + cytosine. In RNA the thymine is replaced by uracil
What parts of the nucleotides make up the rungs of the ladder?
In DNA, the actual nitrogenous base rings make up the "ladder" while the "sides" are made from alternating deoxyribose and phosphate groups.
What is the definition of nucleotide?
Nucleotides are the 'rung' or 'dowel-like' structures that hold the DNA strand together. Nucleotides consist of Purines (adenine and Guanine) and Pyrimidines (Thymine and Cytosine) {{ A to T....G to C}} A neucleotide is an organic compound that is made up of three joined structures. see also site presenting Visualization invented in 2015 by Polish scientist Gregory Podgorniak: studia.scienceontheweb.net/visualization.php

What is the rung of the DNA ladder?
The rungs that are in the DNA ladder molecule are nucleotides. They are adenine, guanine, thymine and cytosine. Deoxyribose and phosphate make up the backbone of the molecule.

How do you spell rung?
rung
How is the word rung used in a sentence?
The word "rung" is used as the past participle of the verb "ring," to indicate the act of sounding a bell or making a ringing sound. For example, "He rung the doorbell to announce his arrival."
To be rang or to be rung?
"To be rung" is the correct form. The verb "ring" changes to "rung" in the past participle form when referring to something that has been rung, like a bell, for example.
What is the homophone for a step of a ladder and twisted?
The homophone for "step of a ladder" and "twisted" is "rung".
