How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde ...

DNA segments that can move from one part of the genome to another—are key to bacterial evolution and the development of ...

Transposons, or "jumping genes" - DNA segments that can move from one part of the genome to another - are key to bacterial ...

A woman's egg cells are already formed in her body before she is born. However, with increasing age, DNA damage accumulates ...

Gene editing techniques may eventually allow trisomy to be treated at the cellular level, according to an in vitro proof-of-concept study.

But some plants have taken a different approach. They have evolved sex chromosomes, the bits of DNA that make individual plants either male or female. In that club are organisms like the ginkgo ...

Scientists are exploring gene editing as a way to correct trisomy at the cellular level. Using CRISPR-Cas9, researchers ...

This valuable work extends previous studies to convincingly show that the centromere-histone core contributes to force transduction through the kinetochore. The centromere mainly strengthens one of ...

Gene editing techniques may eventually allow for trisomy disorders to be treated at the cellular level, according to an in ...
