A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

The table below list organelles, their function and the types of cell that they can be found in. Can you fill in the blanks to complete the table? Cell structure Description Function Cell type Cell ...

All life is made up of cells several magnitudes smaller than a grain of salt. Their seemingly simple-looking structures mask the intricate and complex molecular activity that enables them to carry out ...

The prefrontal cortex region of the human brain is responsible for a range of complex functions from decision-making to certain types of memory. When something goes wrong in this part of the brain, it ...

Improving our understanding of the impact obesity has on individual cells could go a long way to preventing some of its deleterious downstream effects, such as diabetes and cardiovascular disease.

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

Geared toward a younger audience (but honestly, who among us doesn’t love cell animations?) the Cell and Cell Structure app is a great educational resource for those looking for a beautifully ...

It's no coincidence that our bodies feel a little creakier as we age. The trillions of cells that make up our skeleton age too, and some change in ways that weaken the very structure of our bones.
