When a woman becomes pregnant, the outcome of that pregnancy depends on many things — including a crucial event that happened ...

Sezary syndrome (SS), an aggressive leukemia of mature T cells, is more complicated at a molecular level than ever suspected, according to investigators from the Perelman School of Medicine at the ...

Researchers identified a new chromosomal abnormality in acute lymphoblastic leukemia that appears to work in concert with another mutation to give rise to cancer. This latest anomaly is particularly ...

Translocations, in genetics, happen when chromosomes break and the pieces attach to other chromosomes. This mixing of genetic material has important results. The resultant chromosomes are lacking in ...

We have identified two chromosomal genes of Escherichia coli K12 that are required for the expression of conjugative plasmid functions in the presence of normal plasmid DNA. Hfr cells with mutations ...

A research group from the National Cancer Research Center (CNIO) has found that an alteration in the POT1 gene prevents lung tissue from regenerating, which over time makes breathing difficult. The ...

Data from the literature (tables 1, 2; fig. 1) show that the relative probabilities of occurrence for the various categories of spontaneous chromosomal mutations do not match those predicted by both ...

Most cancer researchers are convinced that cancer results from a handful of genetic mutations that kick a cell into uncontrolled growth. UC Berkeley genetics researcher Peter Duesberg disagrees, and ...

A new study by researchers at the RIKEN Center for Integrative Medical Science in Japan reports differences in blood cell mutations between Japanese and European populations. The study found that ...

New research by a scientist at the Milner Center for Evolution at the University of Bath suggests that "selfish chromosomes" explain why most human embryos die very early on. The study, published in ...

Human eggs appear to be protected against a certain type of age-related mutation. In a small study, researchers found no signs that mutations accumulate in the mitochondrial DNA of human egg cells as ...
