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 ...

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.

Some eukaryotes consist of a single cell; but most single-celled creatures are made of simpler cells which lack obvious ...

Why is DNA so important? Put simply, DNA contains the instructions necessary for life. The code within our DNA provides directions on how to make proteins that are vital for our growth, development, ...
