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 ...

They have multiple, larger chromosomes, multiple origins of replication on each chromosome, and some regions of the DNA are more tightly packaged than others, so this form of gene regulation might be ...

Conjugation is a form of horizontal gene transfer that allows the exchange of genetic material between two organisms or cells ...

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 ...

“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, ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this ...

Bacteriophages, the most abundant life form on Earth, infect bacterial cells and influence the structure of the microbial ...

“Bacteria are like these little tinkerers ... allowing the polymerase to wrap around the end of the DNA during replication. This prevents the need for telomerase to maintain the length ...

A new DNA sequencing technique that delivers faster and more accurate bacterial infection diagnoses could be implemented nationwide. The method, developed by the Medicines and Healthcare products ...

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 ...

Some bacteria are refabricated into microspheroids ... ensuring the preservation, access, replication, and management of files within large-scale DNA databases," the researchers write. Despite these ...
