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.
Sister Chromatids (formed during interphase) â These are joined together by a centromere. â¢ Specific DNA sequence. â¢ Bound to the centromere is the kinetochore. â¢ The kinetochore is a disc of proteins which connects the centromere to the spindle fibers.
