Two components make the backbone in DNA, being the deoxy-ribose and phosphate molecules. These molecules link together in a staggered pattern where the deoxy-ribose and phosphate molecules follow one another, like the backbone of a zipper. Deoxy-ribose is a type of sugar molecule where the adenine, guanine, cytosine and thymine molecules attach a covalent bond. The phosphate molecules bond with the deoxy-ribose molecule acting like anchors in DNA.Know More
The structure of a deoxy-ribose molecule is five carbon atoms in a ring with oxygen atoms or oxygen and hydrogen molecules attaching themselves to the carbon. Deoxy-ribose has one fewer oxygen atom than ribose, which is one of the differences between DNA and RNA. Phosphorus and oxygen atoms with oxygen and hydrogen molecules comprise the elements of a phosphate molecule in DNA. Carbon, hydrogen, oxygen and phosphorus in the right amount and combination is all it takes for nature to create a backbone for DNA.
Science explains the way deoxy-ribose and phosphorous molecules stay together as the 3- and 5-prime phosphodiester linkage. This is simply a way of keeping track of the phosphate and deoxy-ribose molecules where 5 ends a phosphate and 3 ends a deoxy-ribose molecule. This linkage is true in all DNA molecules.Learn more about Molecular Biology & DNA
According to The Tech Museum of Innovation, DNA is soluble in water because the sugar and phosphate molecules that make up the DNA backbone are hydrophilic. DNA bases are hydrophobic but are protected from the water by the DNA backbones of the two DNA strands.Full Answer >
The process of DNA replication takes one parental DNA molecule and creates two daughter DNA molecules. This process occurs in the nucleus of the cell and occurs during the cell cycle in eukaryotic cells.Full Answer >
When DNA is denatured, the hydrogen bonds that hold the double helix together break apart, separating the DNA molecule into two single strands. Denaturation occurs as the temperature increases, according to Ian VanLare, Professor of Biology at Tusculum College.Full Answer >
DNA stores information in a sequence of adenine, cytosine, guanine and thymine on a backbone of two deoxyribose molecules, which intertwine in a double helix. In nature, this information is read by RNA molecules and turned into proteins.Full Answer >
