Transcriptomics is a powerful tool for understanding gene structures and RNA-based regulation in any organism. In contrast to the classical 'single gene' reductionist approach, in which biological ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

The main difference between prokaryotic and eukaryotic cells lies in their structure. Prokaryotic cells and eukaryotic cells are the two types of cells that exist on Earth. There are several ...

Eukaryotes are organisms whose cells possess a nucleus enclosed within a cell membrane, making up one of the three domains of life, Eukaryota. They include multicellular organisms such as plants, ...

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size. Every organism visible to the ...

New insights have been gained from the most comprehensive tree of prokaryotic life assembled to date, report scientists. Bacteria were the original masters of their domain, having Earth to themselves ...

The origin of eukaryotes is considered one of the greatest enigmas in biology: according to current doctrine, two prokaryotes, a so-called Asgard archaeon and a bacterium, are believed to have merged.

Prokaryotes contain five different types of DNA polymerase. These are described below. Polymerase I is a DNA repair enzyme from the family A polymerases that has a 5’ to 3’ and 3’ to 5’ activity. Pol ...

Prokaryotic and Eukaryotic Cells: The cell is the basic unit of life and forms the building blocks of all living organisms. It was discovered by Robert Hooke In 1665. Some cells have membrane-bound ...
