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 a specific sequence of DNA that contains the instructions to make a functional product like a protein, while a genome is the complete set of an organism's genetic material, including all its genes. Think of a gene as a single instruction in a recipe book, and the genome as the entire recipe book.
Genome is the entirety of an organism's hereditary information. It is either encoded in DNA or for many viruses, in RNA.
DNA is the molecule that carries genetic information. Genes are segments of DNA that code for specific traits. Chromosomes are structures in the cell that contain DNA, and the genome is the complete set of an organism's genetic material, including all its genes and non-coding sequences.

order from largest to smallest: gene, genome, chromosome, DNA, gene pool
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

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).
A new gene can be inserted into an animal's genome through genetic engineering techniques, such as gene editing or transgenesis. These techniques can replace a faulty gene with a functional one, or introduce a completely new gene into the genome. Additionally, gene therapy can be used to deliver therapeutic genes into an animal's cells to treat genetic disorders.
Biolistic gene transfer is the method commonly used to introduce a gene into the chloroplast genome. It involves using a gene gun to deliver DNA-coated particles into the plant cells, allowing for the incorporation of the gene into the chloroplast DNA.
Only the Cell
The goal is to identify and map the complete set of genetic material within an organism's DNA, known as the genome. This information allows researchers to better understand gene function, genetic variations, and their impact on health and disease. In the case of the human genome, this project is known as the Human Genome Project.
