Both genes and genomes come in a variety of sizes.
About 1,000 base pairs would be enough DNA to encode most proteins. But introns-"extra" or "nonsense" sequences inside genes-make many genes longer than that. Human genes are commonly around 27,000 base pairs long, and some are up to 2 million base pairs.
Very simple organisms tend to have relatively small genomes. The smallest genomes, belonging to primitive, single-celled organisms, contain just over half a million base pairs of DNA.
But among multicellular species, the size of the genome does not correlate well with the complexity of the organism. The human genome contains 3 billion base pairs of DNA, about the same amount as frogs and sharks. But other genomes are much larger. A newt genome has about 15 billion base pairs of DNA, and a lily genome has almost 100 billion.
genome -> chromosome -> DNA -> gene
A gene is just the DNA that stores genetic information, a genome is all the genetic material in an organism.
DNA is the smallest unit say a letter, then Gene it's like word, after that Chromosome it's like a sentence, Finally the biggest unit is Genome it's like a paragraph.
A gene is a functional unit on DNA. A gene codes for a protein. Most of the DNA in a genome does not code for protein. These non-coding sequences are thought to provide a sense of stability and integrity to the genome. If a DNA sequence is capable of coding for a functional protein, then it is a gene
Genome is the entirety of an organism's hereditary information. It is either encoded in DNA or for many viruses, in RNA.

Recombinant DNA can replace a gene in an animal's genome.

Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
