The Nucleolus: How It Has Evolved Over Time
The nucleolus, a small organelle within the nucleus of a cell, plays an important role in the production of ribosomes. Now, researchers from the University of Cambridge have discovered that the nucleolus has evolved over millions of years to become more complex and efficient. By analyzing the genome of a diverse range of organisms, including plants, fungi, and animals, the team found that the nucleolus has become increasingly specialized, with its complexity increasing in tandem with the complexity of the organism itself. The researchers also discovered that the nucleolus has become more efficient, meaning that it is able to produce more ribosomes in a shorter amount of time. This research sheds light on the evolution of the nucleolus and its important role in the production of ribosomes.
