eukaryotic — which have two different types of cells. An organism can be made up of either one type or the other. Some organisms consist of only one measly cell, but even so, that cell will ...

Organelles in cells were originally often independent cells, which were incorporated by host cells and lost their ...

The cellular life cycle, also called the cell cycle, includes many processes necessary for successful self-replication. Beyond carrying out the tasks of routine metabolism, the cell must duplicate ...

Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active ...

Researchers from Northwestern University have stumbled upon a previously unobserved function of a protein found in the cell ...

A recent study by Chinese scientists has revealed the intricate molecular machinery driving energy exchange within ...

Genetic switches could play a role in creating complex eukaryotic genetic circuits for programmed cell-free systems or artificial cells.

DNA segments that can move from one part of the genome to another -- are key to bacterial evolution and the development of antibiotic resistance. Researchers have discovered a new mechanism these ...

The research field of "cellular IRESes" lay dormant for decades, as there was no uniform standard of reliable methods for the ...

The biggest challenge for the researchers was the size and the shape of the bacteria. “So far, we have only used the AFM to study eukaryotic cells, including human cells,” explains Lim. “But ...
