- Which of the following occurs in meiosis but not in mitosis? alignment at the cellular equator chromosome condensation synapsis DNA replicationarrow_forwardIn which of the following ways do polytene chromosomes differ from other chromosomes? Polytene chromosomes are multiple copies of identical single-stranded DNA. Polytene chromosomes can only be found in bacteria. Polytene chromosomes are replicated but not separated. Polytene chromosomes are fully condensed DNA. Polytene chromosomes represent uncoiled versions of meiotic chromosomes.arrow_forwardAlthough you can see chromosomes as they are lined up or being separated during mitosis with a light microscope, you cannot see the DNA while it is being replicated with the same microscope. Why not? Chromosomes do not contain protein until mitosis. Chromosomes are outside the nucleus during replication. Chromosomes are visible only before DNA has been duplicated. Chromosomes are not condensed during S phase so they cannot be seen by light microscopy.arrow_forward
