biology textbooks have neatly compartmentalized cellular functions. Mitochondria are the powerhouses of the cell, the cytoplasm is a bustling factory floor for protein synthesis, and the nucleus a ...
Metabolic enzymes, typically associated with energy production, are now discovered to also play essential roles in the nucleus, such as orchestrating cell division and DNA repair. This breakthrough, ...
Think back to that basic biology class you took in high school. You probably learned about organelles, those little 'organs' inside cells that form compartments with individual functions. For example, ...
The nucleus is the double membrane limited structure within an eukaryotic cell that contains the chromosomes, and where the DNA is replicated or transcribed into RNA. The membrane is perforated by ...
