What is a prokaryotic cell? Prokaryotes are small, single-celled organisms with a simple structure. Unlike other cells, they don’t have a nucleus or other membrane-bound organelles. Instead, most ...

They have both membrane-bound nucleus and organelles. Plants, algae, fungi, protists, and animals are eukaryotic. Examples of protists include amoebas, paramecium, algae, and slime molds.

Eukaryotic cells are more complex than bacteria in many ways, including in terms of transcription. Specifically, in eukaryotes, transcription is achieved by three different types of RNA polymerase ...

In many eukaryotic organisms, the promoter contains a conserved gene sequence called the TATA box. Various other consensus sequences also exist and are recognized by the different TF families.

Every organism visible to the naked eye is a mass of genetically identical cells. Each of these multicellular creatures started as a single cell that divided countless times to produce its body. And ...

A new study challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms. In the beginning, there was boredom. Following the emergence of cellular life on ...

Organisms on planet earth are broadly divided into prokaryotes and eukaryotes. The former are unicellular, do not have any organelles such as mitochondria, and their DNA is not packaged into a ...

Prokaryotes are classified into two domains: bacteria and archaea. Although archaea were once grouped with bacteria, modern research has revealed that bacteria and archaea have distinct biochemical ...
