  3. 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).

  4. 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 or10 −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 ...

  7. Red blood cell - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell

    A typical human red blood cell has a disk diameter of approximately 6.2–8.2 μm [19] and a maximum thickness of 2–2.5 μm and a minimum thickness in the centre of 0.8–1 μm, being much smaller than most other human cells.

  8. Cell nucleus - Wikipedia

    en.wikipedia.org/wiki/Cell_nucleus

    The nuclear envelope separates the fluid inside the nucleus, called the nucleoplasm, from the rest of the cell. 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.

    3–4 μm – size of a typical yeast cell [86] 5 μm – length of a typical human spermatozoon's head [87] 6 μm – thickness of the tape in a 120-minute (C120) compact cassette [88] 7 μm – diameter of the nucleus of a typical eukaryotic cell [citation needed] about 7 μm – diameter of human red blood cells [89]
