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 ...
Mesoscale eddies: hotspots of prokaryotic activity and differential community structure in the ocean
To investigate the effects of mesoscale eddies on prokaryotic assemblage structure and activity, we sampled two cyclonic eddies (CEs) and two anticyclonic eddies (AEs) in the permanent eddy-field ...
Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Eukaryotes developed in a world markedly changed from earlier times.Early prokaryotes, over some 2 ...
In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the ...
The questions in this quiz are suitable for GCSE biology students studying plant cells, animal cells, microscopes, eukaryotes and prokaryotes. If you struggled with the quiz, don't panic - we've got ...
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 earth, ...
