    Aoa Ma'am I have a few questions:
    1) centrosomes are the proteins that make microtubules?
    2) we cannot see the nucleolus or the nuclear envelope in prophase?
    3) In telophase can we see the nucleolus and the nuclear envelope?
    4) do both DNA replication and protein synthesis occur in the S phase?
    5) at 4:35 in video, does one side of the second pink structure (scissor type) represent one chromatid? if there is only one of this structure then it will only be called a chromatid and NOT a chromosome right? because chromosomes have two chromatids not one

      1)alpha and beta tubulin makes up microtubules and 9 triplets of microtubules form centrioles and a pair of centrioles form a centrosome on each pole of cell
      2) no we cannot see them as they disappears
      3)yes we can see them as the are newly forming at that stage
