  2. Monoisotopic element - Wikipedia

    en.wikipedia.org/wiki/Monoisotopic_element

    Monoisotopic elements are characterized, except in one case, by odd numbers of protons (odd Z), and even numbers of neutrons. Because of the energy gain from nuclear pairing, the odd number of protons imparts instability to isotopes of an odd Z , which in heavier elements requires a completely paired set of neutrons to offset this tendency into ...

  3. DNA extraction - Wikipedia

    en.wikipedia.org/wiki/DNA_extraction

    The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. [1] DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other contaminants, and ...

  4. Mononuclidic element - Wikipedia

    en.wikipedia.org/wiki/Mononuclidic_element

    Thus, the element's natural isotopic abundance is dominated by one isotope that is either stable or very long-lived. There are 19 elements in the first category (which are both monoisotopic and mononuclidic), and 2 (bismuth [a] and protactinium) in the second category (mononuclidic but not monoisotopic, since they have zero, not one, stable ...

    en.wikipedia.org/wiki/Bacterial_genome

    Log-log plot of the total number of annotated proteins in genomes submitted to GenBank as a function of genome size. Based on data from NCBI genome reports.. Bacteria possess a compact genome architecture distinct from eukaryotes in two important ways: bacteria show a strong correlation between genome size and number of functional genes in a genome, and those genes are structured into operons.

  6. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The chemical DNA was discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. The DNA segments that carry this genetic information are called genes.

  7. List of sequenced bacterial genomes - Wikipedia

    en.wikipedia.org/wiki/List_of_sequenced...

    This list of sequenced eubacterial genomes contains most of the eubacteria known to have publicly available complete genome sequences. Most of these sequences have been placed in the International Nucleotide Sequence Database Collaboration , a public database which can be searched [ 1 ] on the web .

  8. Alkaline lysis - Wikipedia

    en.wikipedia.org/wiki/Alkaline_lysis

    Alkaline lysis is the process of isolating plasmid deoxyribonucleic acid (DNA) in bacteria. It is a standard method used in molecular biology to isolate the plasmid without obtaining chromosomal DNA. The first alkaline lysis was performed by Birnom and Doly in 1979. [ 1 ]

  9. Stable nuclide - Wikipedia

    en.wikipedia.org/wiki/Stable_nuclide

    The 80 elements with one or more stable isotopes comprise a total of 251 nuclides that have not been shown to decay using current equipment. Of these 80 elements, 26 have only one stable isotope and are called monoisotopic. The other 56 have more than one stable isotope. Tin has ten stable isotopes, the largest number of any element.
