![]() ![]() Each person in the group should practice the entire process. Using your maternal and paternal sets of replicated chromosomes and your notes as a reference, practice the process of mitosis until you are very comfortable with it. Be sure you can identify the sister chromatids, chromosomes, and the difference between a replicated and non-replicated form.ģ. Note that the sister chromatids are identical in color. Replicate your chromosomes! Make enough copies of each chromosome to represent both paternal and maternal chromosomes in a replicated form, as shown below.The maternal and paternal versions are represented by respective bead color. The interphase takes place in the cytoplasm and the cell nucleus. The interphase is the preparation phase for mitosis and it is also the longest phase in the cell cycle. Each chromosome pair consists of a maternal and paternal version of the chromosome. The events of the cell cycle involve cell growth and cell division, of which the interphase defines the phase of cell growth where several metabolic reactions take place. Note that there are four chromosomes here, or two homologous pairs. ![]() This is what your critter’s chromosomes look like in the unreplicated form. Since it has two copies of each chromosome the diploid number is 4 (2 × 2 = 4). We will assume that the critter is diploid (2N) and has two different chromosomes. Set up half of the beads exactly as follows, representing genes on the chromosome of a hypothetical critter.
