Genome Size Evolution: Sizing Mammalian Genomes
Cytogenetic and Genome Research, 2012The study of genome size (GS) and its variation is so fascinating to the scientific community because it constitutes the link between the present-day analytical and molecular studies of the genome and the old trunk of the holistic and synthetic view of the genome.

Within complements the chiasma frequency per chromosome, which directly reflects the amount of recombination, is generally closely correlated with chromosome length, i.e. the chromosomal DNA content. The correlation does not apply when comparisons are made between the complements of different species.

Antonie van Leeuwenhoek, 1996 This manuscript examines genome size in bacteria. The opposing capability of bacteria to alter their genome sizes and order of genes within limits yet remain somewhat constant provides a mechanisms for diversity and evolution in bacterial populations. Bacteria may have evolved by increasing their genome size and changing gene orders with the assistance

The problem of the eukaryotic genome size [PDF]
Biochemistry (Moscow), 2008 The current state of knowledge concerning the unsolved problem of the huge interspecific eukaryotic genome size variations not correlating with the species phenotypic complexity (C-value enigma also known as C-value paradox) is reviewed. Characteristic features of eukaryotic genome structure and molecular mechanisms that are the basis of genome size ...

Genome size evolution in macroparasites
International Journal for Parasitology, 2015Reduction in genome size has been associated not only with a parasitic lifestyle in intracellular microparasites but also in some macroparasitic insects and nematodes. We collected the available data on genome size for flatworms, annelids, nematodes and arthropods, compared those with available data for the phylogenetically closest free-living taxa and

Chromosoma, 1972
Nuclear DNA amounts of fifteen species of placental mammals were determined by Feulgen cytophotometry. Relative values for several widely used species have been ascertained with an error of only a few percent. Absolute values (picograms or numbers of nucleotide pairs) can be determined with an error of about ten percent.

Plant Systematics and Evolution, 1986
The DNA 2C and per chromosome values of 57 species belonging to 22 genera of gymnosperms have been analysed. The overall range is 12-fold with a modal value of about 30.0 pg.Cycadales exhibit a 2-fold difference. AmongConiferales with a 4-fold variation, thePinaceae have higher mean DNA contents as well as a greater range and diversity than other ...

Chromosoma, 1972
Nuclear DNA amounts of twenty-three species of birds from seventeen families of seven orders were determined by Feulgen cytophotometry. Genome size is constant in these birds, the ratio between the largest and smallest genome in the sample is 1.3 to 1.

Genome Size of Mycoplasmal DNA
Nature, 1969ELECTRON microscopic studies of the contour length of DNA from a mycoplasma species, Mycoplasma hominis (H 39)1, have shown that the DNA in this organism is organized in a single circular chromosome, 262 microns long, corresponding to a molecular weight of 5.0 × 108 daltons.
