During the last two decades has been possible to identify the molecular mechanisms that regulate the cell cycle and hence cell division. Accurate knowledge of how a healthy cell divides is useful to understand properly what has not worked in a tumor cell....
The cells of any living being divided by two different mechanisms: through mitosis, which is the way in which cells are involved in normal cell growth in most living organisms, and through meiosis, the process by formed sex cells or germ.The meiotic cell...
The control of gene expression depends on the access of chromatin gene regulatory areas to the transcriptional machinery. The covalent modifications of histones as acetulaciones and methylation are key factors to regulate that access. Reading the...

The specificity of the DNA segments catalyzed by the enzyme DNA ligase can be exploited in systems designed to identify the presence of a target sequence of nucleic acids in a biological sample. The amplification methods based on the ligase can...
The enzyme DNA ligase is essential for DNA replication, recombination and for repair of genetic material in vivo. From virus and both prokaryotic and eukaryotic organisms have been isolated and characterized different DNA ligases, most recently, have been...
