DNA Replication Pattern in Somatic Chromosomes of <i>Crepis capillaris</i>

Somatic Chromosomes of Long-Eared Desert Hedgehog Hemiechinus auritus

Impact of Mutagens on DNA Replication in Barley Chromosomes.

Replication errors that are caused by mutagens are critical for living cells. The aim of the study was to analyze the distribution of a DNA replication pattern on chromosomes of the H. vulgare 'Start' variety using pulse 5-ethynyl-2'-deoxyuridine (EdU) labeling, as well as its relationship to the DNA damage that is induced by mutagenic treatment with maleic hydrazide (MH) and γ ray. To the best...

The units of DNA replication in Drosophila melanogaster chromosomes.

DNA replication in the chromosomes of the chicken, Gallus domesticus.

DNA fibre autoradiography has been used to study the replication of chromosomal DNA from chicken cells in tissue culture at 37 °C. The 5-phase is estimated to be about 75 h. Replication proceeds in the manner first described by Huberman & Riggs. Tandemly arranged units replicate bi-directionally from fork-like growing points, the times of initiation of individual replicating sections being stag...

Initiation of DNA replication at CpG islands in mammalian chromosomes.

CpG islands are G+C-rich regions approximately 1 kb long that are free of methylation and contain the promoters of many mammalian genes. Analysis of in vivo replication intermediates at three hamster genes and one human gene showed that the CpG island regions, but not their flanks, were present in very short nascent strands, suggesting that they are replication origins (ORIs). CpG island-like f...
