So, now that we move on to anaphase. All the same
things are happening. Many of the same cell cycle
controls are in place. Have this spindle fibers pull
chromosomes towards the opposite end of the cell.
Keep in mind the language here is chromosomes.
We're pulling apart homologous chromosomes.
We're pulling apart homologous pairs. I like to
always consider the word replicated so I can keep it
straight in my head. We are not only pulling apart
homologous chromosomes because that's not what's
happening. They are replicated homologous
chromosomes. And in anaphase, those are separated
Right? And then we move on into looking at further
extension. So sister chromatids are still stuck
together moving into the cell. We've got one of
each homolog moving into each new nucleus.
And then we see that there is nuclear envelope
reformation possibly, depending on the species.
We reform the envelope. However, we do not
necessarily have cytokinesis occur between meiosis I
and meiosis II. So, moving forward from here we will
go into meiosis II directly. Again, there is no
synthesis. So we've separated homologous
chromosomes. We don't go through any cell cycle.
We are just going to go boom, straight into
meiosis II and separate the sister chromatids.
So, DNA replication occurs before meiosis I but
does not occur before meiosis II.
