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.

Question: What may be concluded if a particular replacement experiment revealed no foreign growths at the site of cell mass insertion? Explain your answer.
* Will UPVOTE, just please help me answer the question. Thanks.
MAKE CONNECTIONS Look at Figure 12.7 and imagine the twodaughter cells undergoing another round of mitosis, yielding four cells.Compare the number of chromosomes in each of those four cells, aftermitosis, with the number in each cell in Figure 13.8, after meiosis. Whatis it about the process of meiosis that accounts for this difference, eventhough meiosis also includes two cell divisions?
