What compounds are the building blocks of DNA macromolecules? What do transfer RNA molecules do during protein synthesis? The bases are bonded to what part of the backbone of the DNA molecule? If the upper strand of the DNA molecule below acts as a template to make mRNA, what is the nucle...
How does Z-DNA form? As DNA is replicated, which DNA base pair will bond to cytosine? The bases are bonded to what part of the backbone of the DNA molecule? What is a DNA triplet? What is the DNA structure of eukaryotic cells?
DNA is formed by connecting the nucleotides using chemical bonds between the ringlike deoxyribose sugar and the phosphate. Such bonds are called phosphodiester bonds, and the resulting chain of alternating sugar and phosphate is called the sugar-phosphate backbone. The nitrogenous base is not part of...
the chromosomes are made from the dna molecule being tightly coiled and tightly packed. here, the molecule of dna is coiled around proteins known as histones that provide structural support. therefore, molecules of dna as well as histones are the main components of chromosomes. dna molecule deoxyr...
The chemical units are called nucleotides, and each nucleotide has a compound of phosphate sugar which is the backbone, and a sugar deoxyribose. The Phosphates and sugars are the same in all nucleotides but the one thing that is different would be the bases. DNA bases are cytosine, thymine,...
Later studies found that the sides of the DNA ladder are composed of what Miescher's work hinted at:phosphate and deoxyribose molecules. These phosphate and deoxyribose molecules form the backbone of DNA. Continued studies of DNA eventually led to Crick and Watson's realization that the DNA molec...
in many inorganic and in all organic compounds, exists freely in amorphous, graphite, and diamond forms and as a constituent of coal, limestone, and petroleum, and is capable of chemical self-bonding to form an enormous number of chemically, biologically, and commercially important molecules. Othe...
The-atechemicals in these everyday products are formally known as esters (R-COOR’) and are a type oforganic compound. Generally formed from the union of two other organic compounds, esters are universal in nature; from nanoscopicDNAmolecules to giant plastics, they can be foundeverywhere. ...
In a "standard" DNA nucleotide, deoxyribose and the phosphate group form the "backbone" of the double-stranded molecule, with phosphates and sugars repeating along the outer edges of the spiraling helix. The nitrogenous bases, meanwhile, occupy the interior portion of the molecule. Critically, the...
Iron is therefore alloyed with carbon to form mild steel. This composite is exceptionally strong and durable, and remains the backbone of the industrialized world. (Photo Credit: bezaat.com) However, while the carbon might make mild steel tougher and more robust than aluminum or unable to ...
