Do the steps of the cell cycle also happen before meiosis I?

Like G1 -> S -> G2 -> Meiosis I -> Meiosis II = 4 haploid cells

I know that DNA replication takes place before meiosis I but do G1 and G2 also happen.

And are there checkpoints in place during meiosis just like there are during mitosis?
