A genome is the complete set of genetic material present in an organism. It includes all of an organism's genes, as well as non-coding sequences of DNA or RNA.
A genome is composed of DNA n most organisms, though some viruses have RNA genomes.
In eukaryotic organisms, the genome is organized into chromosomes, which are long, thread-like structures located in the cell nucleus.
Genome size varies widely among organisms. For example, the human genome consists of approximately 20,000-25,000 genes.
Sequencing the genome involves determining the order of nucleotides in DNA.
Genome research has numerous applications, including in medicine, agriculture , and evolutionary biology.
