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 ...
You know when you hear somebody start a sentence with, "There are two kinds of people..." and you think to yourself "Oh boy, here it comes." But what if I were to tell you that there are just two ...
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 ...
The Argonaute (Ago) enzyme complex plays a critical role in DNA and RNA target cleavage for a process known as RNA silencing in prokaryotic and eukaryotic cells, making them a target for future ...
Eukaryotes—fungi, plants, us—are complex. Our large cells are characterized by their different compartments, many of which are neatly enclosed within a boundary of membrane. These compartments contain ...
Chloroplasts arose from cyanobacteria, mitochondria arose from proteobacteria. Both organelles have conserved their prokaryotic biochemistry, but their genomes are reduced, and most organelle proteins ...
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 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.
