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 ...

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

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

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

Researchers have uncovered mechanisms by which mobile genetic elements integrate into the chromosomes of bacteria with linear genomes.

The nucleus of every human cell contains chromosomes—23 pairs, to be exact. These carry our genetic material, known as the genome, and are composed of deoxyribonucleic acid (DNA) and proteins.

Based on early Phase I/II data, investigators at Cincinnati Children's are enrolling more patients with a telomere biology ...

conica and S. vulgaris). Epigenetic analyses included DNA methylation and small RNA profiling. Mutants with Y chromosome deletions affecting sex phenotypes were sequenced to identify candidate sex ...
