Can someone give me an outline of the molecular mechanisms behind why DNA Acetylation, Methylation, Phosphorylation and general structure (i.e. nucleosomes etc) affect genetic expression/transcription etc? I get how these changes take place, but not how they affect phenotypes. Any accessible webpages would also be a massive help. Thanks everyone!

Genetic recombination (in particular the exchange of genes (DNA) between homologous chromosomes) sometimes takes place in meiosis:

a. after the first cell division
b. before the DNA synthesis
c. prior to the first metaphase
d. between nonhomologous chromosomes

I thought it was c but the word "sometimes" is throwing me off. Maybe d?? I don't see anything about nonhomologous chromosomes in my book though.
