During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder.

DNA ladder formation could be clearly observed when the HL-60 cells incubated for 4, 16, 20 and 22 h in cultures exposed to etoposide (lanes 5–8). The ladder of DNA fragments of approximately ...

Magnetic-field-induced DNA strand breaks in brain cells of the rat.. Environmental Health Perspectives , 2004; 112 (6): 687 DOI: 10.1289/ehp.6355 Cite This Page : ...

You have more than 2 metres of DNA inside every cell. But is very tightly coiled up so it all fits. DNA is like a code containing all the instructions that tell a cell what to do. It is made up of ...

To conclude, a practical technique for analyzing DNA fragmentation in apoptosis is provided by TUNEL staining. References Gao Y et al. Reproductive Biology and Endocrinology 15:94 (2017) ...

In order to study the mechanism of the effect of heparin on apoptosis in carcinoma cells, the nasopharyngeal carcinoma cell line CNE2 was used to identify the effect of heparin on apoptosis ...

The molecular double-helix of DNA resembles a twisted ladder consisting of two strands connected by “rungs” called bases. The bases, which are known by the abbreviations A, T, ...

George Perry University of Texas at San Antonio; Posted: 26 Feb 2004 DNA Damage Mediated Cell Cycle Reentry in AD The search to elucidate pathologic mechanisms of neuronal death in Alzheimer's disease ...

A genome contains all the genetic information needed to create and maintain an individual. Sequencing a genome helps scientists better understand genomes and their role in creating organisms. When ...

Fifty-nine years after James Watson and Francis Crick deduced the double-helix structure of DNA, a scientist has captured the first direct photograph of the twisted ladder that props up life. Enzo ...

The final common mistake that mangles otherwise decent images of DNA is the number of base pairs per 360 degree rotation of the helix. There should be ten, but all too often the "rungs" of the DNA ...
