How Does a Cell Maintain its Identity During Replication?

Prior to cell division, chromosomes are seemingly a jumbled mess. During cell division, parent cell chromosomes and their duplicates sort themselves out by condensing, becoming...
Heart Failure

Penn Researchers Closer to Uncovering a New Feature in Heart Failure

Each cell in the average human body contains 23 pairs of chromosomes, with four telomeres on each pair. Telomeres cover the end of the...
