Latest Cytogenetics Stories
Cells trying to keep pace with constantly changing environmental conditions need to strike a fine balance between maintaining their genomic integrity and allowing enough genetic flexibility to adapt to inhospitable conditions.
A healthy genome is characterized by 23 pairs of chromosomes, and even a small change in this structure — such as an extra copy of a single chromosome — can lead to severe physical impairment.
They are the Robinson Crusoes of the intracellular world -- lone chromosomes, whole and hardy, stranded outside the nucleus where their fellow chromosomes reside.
Aria Diagnostics (formerly Tandem Diagnostics), a molecular diagnostics company, today announced publication of data supporting a directed, non-invasive approach to cell-free DNA (cfDNA) analysis in maternal blood for evaluation of two common fetal trisomies linked to genetic disorders.
A new University of Florida study shows genomes of a recently formed plant species to be highly unstable, a phenomenon that may have far-reaching evolutionary consequences.
All 10 trillion cells in the adult human body are genetically identical, but develop into distinct cell types, such as muscle cells, skin cells or neurons, by activating some genes while inhibiting others.
