DNA supercoiling is important for DNA packaging within all cells. Because the length of DNA can be thousands of times that of a cell, packaging this genetic material into the cell or nucleus (in eukaryotes) is a difficult feat. Supercoiling of DNA reduces the space and allows for DNA to be packaged. In prokaryotes, plectonemic supercoils are predominant, because of the circular chromosome and relatively small amount of genetic material. In eukaryotes, DNA supercoiling e… Webiv) The two strands of the DNA double helix unwind with the help of a DNA unwinding protein and an enzyme helicase denoted in bacteria named E. coli. This type of unwinding …

Myoglobin is a relatively small protein that contains 150 amino acids. The functional unit of myoglobin is an iron–porphyrin complex that is embedded in the protein (Figure 4.2.1). In myoglobin, the heme iron is five-coordinate, with only a single histidine imidazole ligand from the protein (called the proximal ...
WebThe α-helix is described in every biochemistry text book and widely on the web. It has 3.6 residues per helical turn and has 13 atoms in the ring formed by the hydrogen bond and … A superhelix is a molecular structure in which a helix is itself coiled into a helix. This is significant to both proteins and genetic material, such as overwound circular DNA. The earliest significant reference in molecular biology is from 1971, by F. B. Fuller: A geometric invariant of a space curve, the writhing number, is defined and studied. For the central curve of a twisted cord the writhing number measures the extent to which coiling of the c…
WebA. Rich, F. H. C. Crick, and G. Ramachandran have shown that the rodlike collagen molecule is formed by the braiding of three polypeptide chains. Each chain, like polyproline, is twisted to form a left-handed helix having three amino acids per turn (i.e., n= -3), and these are twisted around one another to form a super helix that is right-handed.
