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.
When the chromosomes have completely migrated to the spindle poles, the kinetochore microtubules begin to disappear, although the polar microtubules continue to elongate. This is the junction between late anaphase and early telophase, the last stage in chromosome division.
