Chromosomes are thread-like structures located inside the nucleus of plant and animal cells, made of DNA tightly coiled around proteins called histones

Histones are highly alkaline, positively charged proteins found in eukaryotic cell nuclei that act as structural spools, allowing long DNA molecules to wrap around them and form nucleosomes

Chromatin is a complex mixture of DNA, RNA, and proteins (primarily histones) found in the nucleus of eukaryotic cells that packages long DNA molecules into dense, compact structures.

each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.

A centromere is the specialized, constricted region of a eukaryotic chromosome that holds sister chromatids together and acts as the attachment site for spindle fibers during cell division (mitosis and meiosis)

A nucleotide is the fundamental building block of nucleic acids (DNA and RNA), consisting of a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group

a pair of parallel helices intertwined about a common axis, especially that in the structure of the DNA molecule.

The base pair rule, or Chargaff’s rules, dictates that in DNA, adenine (A) always pairs with thymine (T), and guanine (G) pairs with cytosine (C)
