Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred ...

A chromosome is comprised of a single DNA molecule that may be either circular or linear. The full complement of a cell s chromosomes is called the genome. The mechanisms underlying bacterial ...

Fourteen (36.8%) subjects above school age have received a statement of special educational needs. Molecular genetic analysis was performed in 42 subjects and has identified maternal uniparental ...

Scientists report adaptive divergence in cryptic color pattern is underlain by two distinct, complex chromosomal rearrangements, where millions of bases of DNA were flipped backwards and moved from ...

A global infestation of bed bugs after World War II was nearly eradicated in the 1950s with the use of the pesticide dichloro ...

Welshons, W. J., and Russell, L. B., Proc. U.S. Nat. Acad. Sci., 45, 560 (1959).

Due to the genetic uniformity within bed bug infestations resulting from extensive inbreeding, one specimen per sample is generally representative of that population. But Booth wanted to make sure ...

That's because sex — and gender roles, too —permeates all the way down to the most unreproductive of cell types. If you want to do science about animals including humans, sex as a biological variable ...

Butch Wilmore and Suni Williams will have to recover from their time in space. Learn more about what happens to the human ...

Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of ...

Research on guinea pig embryos uncovers similarities to human embryogenesis, advancing understanding of preimplantation ...

The country’s largest-ever genomic study has identified unique genetic variants—a crucial step in closing a longstanding gap ...
