The second stage of glycolysis is an isomerization reaction. In this reaction the glucose-6-phosphate is rearranged into fructose-6-phosphate by the enzyme glucose phosphate isomerase. This is a reversible reaction under normal conditions of the cell.
Kinetochore. A specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape; the centromere is difficult to sequence. Please contribute to this project, if you have more information about this term feel free to edit this page.
The Caenorhabditis elegans kinetochore reorganizes at prometaphase and in response to checkpoint stimuli. Likewise, within the paired kinetochores, one kinetochore represents the plus face (depicted in black in Figures 1 and 2), while the other represents the minus face (shown in red).
