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.
Centromere and kinetochore regions in chromosomes play a major role during the cell division. Centromere. A centromere is a highly constricted region on a chromosome to which the spindle attaches during the process of mitosis and meiosis. These special regions contain non-histone proteins that protect them from endonuclease digestion and it is free of nucleosomes and de-condensed.
