  2. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    Most human cells are diploid so they contain twice as much DNA (~6.2 billion base pairs). In 2023, a draft human pangenome reference was published. [8] It is based on 47 genomes from persons of varied ethnicity. [8] Plans are underway for an improved reference capturing still more biodiversity from a still wider sample. [8]

  3. DNA - Wikipedia

    For example, the human mitochondrial DNA forms closed circular molecules, each of which contains 16,569 [33] [34] DNA base pairs, [35] with each such molecule normally containing a full set of the mitochondrial genes.

  5. Human Genome Project - Wikipedia

    en.wikipedia.org/wiki/Human_Genome_Project

    The human genome has approximately 3.1 billion base pairs. [66] The Human Genome Project was started in 1990 with the goal of sequencing and identifying all base pairs in the human genetic instruction set, finding the genetic roots of disease and then developing treatments. It is considered a megaproject.

  6. Human genetic variation - Wikipedia

    en.wikipedia.org/wiki/Human_genetic_variation

    The human genome has a total length of approximately 3.2 billion base pairs (bp) in 46 chromosomes of DNA as well as slightly under 17,000 bp DNA in cellular mitochondria. In 2015, the typical difference between an individual's genome and the reference genome was estimated at 20 million base pairs (or 0.6% of the total). [2]

  7. Genome size - Wikipedia

    en.wikipedia.org/wiki/Genome_size

    Genome size ranges (in base pairs) of various life forms. Genome size is the total amount of DNA contained within one copy of a single complete genome.It is typically measured in terms of mass in picograms (trillionths (10 −12) of a gram, abbreviated pg) or less frequently in daltons, or as the total number of nucleotide base pairs, usually in megabases (millions of base pairs, abbreviated ...
