  2. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    This represents the size of a composite genome based on data from multiple individuals but it is a good indication of the typical amount of DNA in a haploid set of chromosomes because the Y chromosome is quite small. [7] Most human cells are diploid so they contain twice as much DNA (~6.2 billion base pairs).

  3. 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 ...

    It then copies the gene sequence into a messenger RNA transcript until it reaches a region of DNA called the terminator, where it halts and detaches from the DNA. As with human DNA-dependent DNA polymerases, RNA polymerase II, the enzyme that transcribes most of the genes in the human genome, operates as part of a large protein complex with ...

    en.wikipedia.org/wiki/Cell_nucleus

    The size of the nucleus is correlated to the size of the cell, and this ratio is reported across a range of cell types and species. [9] In eukaryotes the nucleus in many cells typically occupies 10% of the cell volume. [10]: 178 The nucleus is the largest organelle in animal cells.
