Prokaryotes, which include bacteria and single-celled microorganisms called Archaea, usually pass their chromosomal DNA on to their offspring asexually. In other words, a bacterial cell reproduces ...

Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique ...

Before we understood that DNA was the genetic code, scientists knew that bacteria transferred it between cells. In 1928, 25 years before the structure of DNA was solved, British bacteriologist ...

Bacteria need to be able to adapt to the changing and challenging environments in which they live to survive and multiply. One of the genetic processes by which they do this is transduction. In this ...

Bacteria are amongst the simplest of organisms - they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi. Size Most are 5 μm - 100 μm.

The CRISPR-Cas5-HNH/Cascade complex, which serves as an immune defense system in prokaryotes, has long been studied for its ability to protect bacteria from invading genetic materials. However ...

Bacteriophages, the most abundant life form on Earth, infect bacterial cells and influence the structure of the microbial community. To fend off phage attacks, bacteria have evolved their own ...

Protein synthesis refers to the process by which cells construct proteins. It's a fundamental cellular mechanism for all living organisms, as proteins carry out enzymatic activities, structural ...
