All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required for that organism. However, DNA does more than specify ...

Although all of the cells that make up a multicellular organism contain identical genetic information, functionally different cells within the organism use different sets of catalysts to express ...

elegans. Translucent and easy to raise, the thousand-celled nematode fills petri dishes in labs all over the world and is probably the best-understood multicellular organism in science.

Later, animals—multicellular organisms—evolved, developing from a single egg cell to form complex beings. This embryonic development follows precise stages that are remarkably similar between ...

As cells were subjected to specific pressures, they transitioned from solitary organisms to interconnected ... Tissue-like multicellular development triggered by mechanical compression in archaea ...

Despite each member of this bacterial clan existing as a single-celled organism, none of them can survive that way. Instead, they combine together and act as one giant, multicellular organism that ...
