Latest Chromosome Stories
Each time a cell divides -- and it takes millions of cell divisions to create a fully grown human body from a single fertilized cell -- its chromosomes have to be accurately divvied up between both daughter cells.
North Carolina State University researchers have uncovered evidence that evolutionary “breakpoints” on canine chromosomes are also associated with canine cancer.
An international team of scientists, including biologists from the University of North Carolina at Chapel Hill, may have pinpointed for the first time the mechanism responsible for cell polyploidy, a state in which cells contain more than 2 paired sets of chromosomes.
In 2009, the DNA alphabet expanded. Scientists discovered that an extra letter or "sixth nucleotide" was surprisingly abundant in DNA from stem cells and brain cells.
Two remarkable discoveries were today revealed by researchers into genome analysis of Leishmania parasites.
Geneticists at Emory University School of Medicine have demonstrated a method that enables the routine amplification of all the genes on the X chromosome.
In order for cells of different types to maintain their identities even after repeated rounds of cell division, each cell must "remember" which genes were active before division and pass along that memory to its daughter cells.
New findings of researchers from the University of Modena and Reggio Emilia (Mauro Mandrioli, Valentina Monti and Gian Carlo Manicardi) show that in aphids the two X chromosomes have a different inheritance.
In children with genomic disorders, often a gamete – egg or sperm – has gone disastrously awry with either a duplication or deletion of genetic material that results in physical and neurological problems for the subsequent child.
