This topic explores how chromatin structure and epigenetic mechanisms regulate marine invertebrate responses to climate change-related stressors, including ...

A single DNA letter, inserted into a stretch of the genome that doesn’t code for any protein, was enough to turn genetically female mouse embryos into anatomically male mice. The experiment, published ...

When bacteria cells replicate, they do so a little differently than human cells do. They don’t undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

Top: Chromosome separate with functioning SMC in two models, line drawing and filled-space. The red and pink dots indicate, respectively, ori on each copy of DNA. Bottom: DNA separating without ...

A study published in Science in the last week of February examined genomic data from three female Neanderthals who lived 1,22,000, 80,000 and 52,000 years ago respectively. The team of scientists ...

This narrated computer animation, with an original musical score, illuminates cellular mitosis. DNA self-replicates; chromosomes divide into two daughter cells; but it begins with a hormone entering ...

For more than five centuries, Leonardo Da Vinci has been celebrated as a visionary artist, scientist, and inventor, known for his extraordinary talent and groundbreaking experiments. Today, an ...

Gene editing techniques may eventually allow trisomy to be treated at the cellular level, according to an in vitro proof-of-concept study. Down syndrome is caused by the presence of a third copy of ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 chromosomes ...
