DNA is the storage of information.
DNA is the main component of chromosomes.
A chromosome is a singular piece of DNA.
chromatids are identical copies of a chromosome.
Gene is a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring
DNA : Storage unit of hereditary information.
Genes : Coding in the DNA.
Chromatids : Thread like hypercoiled structures inside the nucleus, containing DNA.
Chromosomes : Highly condensed chromatids.
Explanation:
DNA : Deoxyribonucleic Acid, is a double-stranded macromolecule, composed of polynucleotides. The polynucleotides are comprised of purine-pyrimidine pairing, bonded together in a large double-helix structure, containing a phosphate-sugar backbone. This macro-structural nucleic acid is termed as DNA. It simply stores all the hereditary information.
Genes : It is the coding in the DNA; a sequence of three consecutive nitrogenous bases collectively called codons, which simply determine for a protein that in turn is responsible for a particular hereditary trait.
Chromatids : Inside the nucleus of a cell at any moment, DNA is found in a highly complex state of compaction. These are called chromatin fibres or chromatids.
Chromosomes : The chromatids condense during cell division to form structures of homologous pairs called chromosomes to ensure that, each cell after the division obtains both the paternal and the maternal genetic material.
