2004). Also, whereas bacterial chromosomes are circular, eukaryotic chromosomes are linear. During circular DNA replication, the excised primer is readily replaced by nucleotides, leaving no gap ...

“Wild stuff does happen.” The trillions of bacteria in our bodies regularly exchange DNA with each other, but the idea that their genes could end up in human DNA has been very controversial. In 2001, ...

Cells must integrate their growth, DNA replication and cell division cycles to ensure faithful inheritance of their genetic material. It was previously thought that, in bacteria, the growth ...

The genome structure—how genes are organized within DNA sequences in an organism—is fundamental to the processes and ...

MONDAY, April 21, 2025 (HealthDay News) -- For uncomplicated urogenital gonorrhea, gepotidacin, which inhibits bacterial DNA replication, is noninferior to ceftriaxone plus azithromycin ...

This new study provides definitive evidence about how these secondary DNA structures can pose physical barriers to DNA ...

This kit was created to enable the rapid spin column-based extraction of genomic DNA from up to 2 × 10 9 viable bacterial cells (typically from 0.5 to 1.0 mL of culture). It’s suitable for both ...

Donald Coffey, a longtime professor at Johns Hopkins University, discovered the nuclear matrix within cells and its role in DNA replication ... how early exposure to a DNA-damaging toxin from gut ...

The repair enzymes are remarkably conserved from bacteria to fungi to humans, underscoring the premium placed on maintaining genomic integrity in the face of a mutagenic burden. DNA is susceptible to ...

A type of virus thought to be a 'mere curiosity' is plentiful in one common bacteria, and possibly others, a research team has found. The discovery improves understanding of how viruses work and could ...
