  2. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    The human genome is a complete set of nucleic acid sequences for humans, encoded as the DNA within each of the 24 distinct chromosomes in the cell nucleus. A small DNA molecule is found within individual mitochondria. These are usually treated separately as the nuclear genome and the mitochondrial genome. [1]

  4. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    The set of chromosomes in a cell makes up its genome; the human genome has approximately 3 billion base pairs of DNA arranged into 46 chromosomes. [96] The information carried by DNA is held in the sequence of pieces of DNA called genes .

    An image of the 46 chromosomes making up the diploid genome of a human male (the mitochondrial chromosomes are not shown). A genome is all the genetic information of an organism. [1] It consists of nucleotide sequences of DNA (or RNA in RNA viruses).

  6. Chromosome 1 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_1

    Chromosome 1 is the designation for the largest human chromosome. Humans have two copies of chromosome 1, as they do with all of the autosomes , which are the non- sex chromosomes . Chromosome 1 spans about 249 million nucleotide base pairs , which are the basic units of information for DNA . [ 4 ]

  7. Y chromosome - Wikipedia

    en.wikipedia.org/wiki/Y_chromosome

    The human Y chromosome is composed of about 62 million base pairs of DNA, making it similar in size to chromosome 19 and represents almost 2% of the total DNA in a male cell. [54] [55] The human Y chromosome carries 693 genes, 107 of which are protein-coding. [56]

  9. Genomic DNA - Wikipedia

    en.wikipedia.org/wiki/Genomic_DNA

    Most organisms have the same genomic DNA in every cell; however, only certain genes are active in each cell to allow for cell function and differentiation within the body. [2] gDNA predominantly resides in the cell nucleus packed into dense chromosome structures. Chromatin refers to the combination of DNA and proteins that make up chromosomes.
