Study shows how telomerase can run amok, deleteriously capping damaged DNA, were it not for a first responder to DNA damage. The natural ends of chromosomes appear alarmingly like broken DNA, much as ...

A central question in molecular biology is how cells protect their chromosomes from damage during repeated cell division. At the heart of this protective process is an enzyme called telomerase. Now an ...

Research has recently uncovered a crucial step in the telomerase enzyme catalytic cycle. This catalytic cycle determines the ability of the human telomerase enzyme to synthesize DNA. Research from the ...

Cancer is a significant cause of death worldwide and many efforts have been devoted to the development of methods for early detection. Telomerase are considered as a tumor biomarker for early ...

Telomerase's reputation is that it has an important role in maintaining the ability of stem cells to divide through maintaining telomeres, the structures at the tips of chromosomes that shorten with ...

Science has identified in the plant kingdom the “missing link” of cellular immortality between human and single-celled animals, according to a new study led by scientists from Arizona State University ...

Researchers at Arizona State University’s (ASU) School of Molecular Sciences and the Biodesign Institute’s Center for the Mechanism of Evolution have discovered an unprecedented pathway producing ...

As DNA strands ravel and unravel in an intricate dance, one notable event takes center stage: replication. This process is essential to life, but the finer details of its orchestrated steps are still ...
