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

How did humans evolve brains capable of complex language, civilization, and more? Scientists at UC San Francisco recently ...

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.

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.

22 pairs of autosomes and 1 pair of sex chromosomes (XX: female or XY: male). During mitosis, as cells repair and replace themselves, DNA is transferred to each daughter cell and becomes an exact ...

Students at Ralston High School recently tested dogs’ DNA as part of a project examining the connection between canines’ ...

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 ...

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