  2. Provirus - Wikipedia

    en.wikipedia.org/wiki/Provirus

    Proviruses may account for approximately 8% of the human genome in the form of inherited endogenous retroviruses. [3] [4] A provirus not only refers to a retrovirus but is also used to describe other viruses that can integrate into the host chromosomes, another example being adeno-associated virus. Not only eukaryotic viruses integrate into the ...

  3. Phi X 174 - Wikipedia

    en.wikipedia.org/wiki/Phi_X_174

    The phi X 174 (or ΦX174) bacteriophage is a single-stranded DNA virus that infects Escherichia coli. This virus was isolated in 1935 by Nicolas Bulgakov [1] in Félix d'Hérelle's laboratory at the Pasteur Institute, from samples collected in Paris sewers. Its characterization and the study of its replication mechanism were carried out from ...

    en.wikipedia.org/wiki/Chromosome_22

    Chromosome 22 is one of the 23 pairs of chromosomes in human cells.Humans normally have two copies of chromosome 22 in each cell. Chromosome 22 is the second smallest human chromosome, spanning about 51 million DNA base pairs and representing between 1.5 and 2% of the total DNA in cells.

  5. 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. Virus classification - Wikipedia

    en.wikipedia.org/wiki/Virus_classification

    Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms. Viruses are classified by phenotypic characteristics, such as morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause.

  8. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    It consists of 22 autosomes plus one copy of the X chromosome and one copy of the Y chromosome. It contains approximately 3.1 billion base pairs (3.1 Gb or 3.1 x 10 9 bp). [ 6 ] 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 ...

  9. Genetics - Wikipedia

    en.wikipedia.org/wiki/Genetics

    Chromosomes are copied, condensed, and organized. Then, as the cell divides, chromosome copies separate into the daughter cells. When cells divide, their full genome is copied and each daughter cell inherits one copy. This process, called mitosis, is the simplest form of reproduction and is the basis for asexual reproduction. Asexual ...
