Which phase is described below? The chromosomes condense, Each is made of two sister chromatids,(looks) like an "X" Each sister is a clone, the closest of kin, And acentromere connects them like siamese twinsThe nucleolus disappears it melts away, as the cell takes a ribosomeproduction holiday, the centrosomes separate, start spindle formationfor separating chromatids and cell elongation.

Question: How chromatids and centromeres are connected together? N.B: Which substance is responsible for the bonding of chromatids and centromeres. Don't Answer like this:Due to continuous dehydration nuclear chromatin condenses to form visible thread like structure, known as chromosome. Then each chromosome divides longitudinally into two chromatid. The sister chromatids are joined together at their centromere.
ganism you are working with has the following chromosomes. Place the chromosomes of this organism onto the cell below such that the diagram accurately shows a cell from this organism in metaphase of mitosis. Note 1: Only place chromosomes you need. You don't need them all. Note 2: You can place the 'Blank Box' image if you don't think you need a chromosome at a particular position. Deshed ine the metaphase plate
