Scientists have discovered a mutation in female drosophila flies that results in infertility. the mutation causes phosphorylation of an amino acid in histones, preventing the histones from binding to dna during cell division. histones are proteins that exist in the nucleus and that package dna into organized units.

explain how this mutation would most likely affect a drosophila fly’s cells during mitosis and meiosis.
explain how phosphorylation of an amino acid could affect chromosomes and cell division, based on how dna, histones, and chromosomes are related.
