  3. Extrachromosomal circular DNA - Wikipedia

    en.wikipedia.org/wiki/Extrachromosomal_circular_DNA

    Extrachromosomal circular DNA (eccDNA) is a type of double-stranded circular DNA structure that was first discovered in 1964 by Alix Bassel and Yasuo Hotta. [1] In contrast to previously identified circular DNA structures (e.g., bacterial plasmids, mitochondrial DNA, circular bacterial chromosomes, or chloroplast DNA), eccDNA are circular DNA found in the eukaryotic nuclei of plant and animal ...

  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 (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 ...

  6. List of organisms by chromosome count - Wikipedia

    en.wikipedia.org/wiki/List_of_organisms_by...

    The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.

  7. C-value - Wikipedia

    en.wikipedia.org/wiki/C-value

    C-value is the amount, in picograms, of DNA contained within a haploid nucleus (e.g. a gamete) or one half the amount in a diploid somatic cell of a eukaryotic organism. In some cases (notably among diploid organisms), the terms C-value and genome size are used interchangeably; however, in polyploids the C-value may represent two or more genomes contained within the same nucleus.

    The metric for genome size was the number of base pairs, the fundamental units of DNA, in an organism's cellular nuclei. If stretched out like from a ball of yarn, the length of the DNA in each ...

  9. Genomic DNA - Wikipedia

    en.wikipedia.org/wiki/Genomic_DNA

    When a cell is not dividing, chromosomes exist as loosely packed chromatin mesh. [3] The genome of an organism (encoded by the genomic DNA) is the (biological) information of heredity which is passed from one generation of organism to the next. That genome is transcribed to produce various RNAs, which are necessary for the function of the organism.
