  2. Base pair - Wikipedia

    en.wikipedia.org/wiki/Base_pair

    bp = base pair—one bp corresponds to approximately 3.4 Å (340 pm) [14] of length along the strand, and to roughly 618 or 643 daltons for DNA and RNA respectively. kb (= kbp) = kilo–base-pair = 1,000 bp

  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 ...

  4. Nucleic acid double helix - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_double_helix

    In an aqueous solution, the average persistence length has been found to be of around 50 nm (or 150 base pairs). [43] More broadly, it has been observed to be between 45 and 60 nm [44] or 132–176 base pairs (the diameter of DNA is 2 nm) [45] This can vary significantly due to variations in temperature, aqueous solution conditions and DNA ...

    The blue scale to the left of each chromosome pair (and the mitochondrial genome) shows its length in terms of millions of DNA base pairs Further information: Karyotype In humans, the total female diploid nuclear genome per cell extends for 6.37 Gigabase pairs (Gbp), is 208.23 cm long and weighs 6.51 picograms (pg).

  6. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    The total length of the human ... has about 100 active copies per ... In other words, between humans, there could be +/- 500,000,000 base pairs of DNA, some being ...

  7. Nucleic acid structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_structure

    Length of the helix turn; Number of base pairs per turn; Difference in size between the major and minor grooves [3] The tertiary arrangement of DNA's double helix in space includes B-DNA, A-DNA, and Z-DNA. Triple-stranded DNA structures have been demonstrated in repetitive polypurine:polypyrimidine Microsatellite sequences and Satellite DNA.

  8. A-DNA - Wikipedia

    en.wikipedia.org/wiki/A-DNA

    Like the more common B-DNA, A-DNA is a right-handed double helix with major and minor grooves. However, as shown in the comparison table below, there is a slight increase in the number of base pairs (bp) per turn. This results in a smaller twist angle, and smaller rise per base pair, so that A-DNA is 20-25% shorter than B-DNA.

  9. Coverage (genetics) - Wikipedia

    en.wikipedia.org/wiki/Coverage_(genetics)

    The average coverage for a whole genome can be calculated from the length of the original genome (G), the number of reads (N), and the average read length (L) as /. For example, a hypothetical genome with 2,000 base pairs reconstructed from 8 reads with an average length of 500 nucleotides will have 2× redundancy.
