  • Nucleoid is an undefined nuclear region of the prokaryotic cell, containing the genetic material (nucleic acids).
  • Chromosomes are thread-like condensed chromatin fibres which contain heredity information and are visible only during cell division.
  • A chromatid is one half of a replicated chromosome. Prior to cell division, chromosomes are copied and identical chromosome copies join together at their centromeres. Each strand of one of these chromosomes is a chromatid. 
  • Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus.
