The most complex genome among all organisms is found in eukaryotes, which include plants, animals, fungi, and protists. Eukaryotic genomes are more complex than prokaryotic genomes due to their larger size and higher levels of organization, including the presence of multiple chromosomes and introns.
Most viruses with single-stranded genomes are simpler in structure and replicate more quickly, while larger viruses with double-stranded genomes tend to have more complex genetic material and biological machinery, which may require a double-stranded genome for stability and efficiency in storing and replicating genetic information.
The organism with the most genes in its genome is the marbled lungfish, which has around 133,000 genes.
The kingdom Animalia contains the most complex organisms on the planet that are multicellular and heterotrophic. These organisms have specialized tissues and organ systems, showcasing high levels of complexity compared to other kingdoms such as Plantae or Fungi.

Humans are not the most complex organisms. Water fleas are the most complex organisms, containing 31,000 genes, about 25% more than the average human. Their body has enough genes to transform itself based on the environment it's in.
nucleus → chromosome → gene
yes, but many viruses do not have DNA genome, but RNA genome.

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.
Most children outgrow these complexes before adulthood.

The most complex single-celled organisms are known as eukaryotic microorganisms. These organisms possess a nucleus and other membrane-bound organelles, which differentiate them from prokaryotic microorganisms like bacteria. Examples include protists like amoebas and paramecia.
