Actin and ARPs in the nucleus Speculation on the potential role of actin in the nucleus derives largely from its known functions as a cytoskeletal protein 1 (Box 1).

Nucleons, which include protons and neutrons, are the composite particles that make up atomic nuclei. While these particles have been widely studied in the past, their internal structure has not yet ...

Do eukaryotic cells have a nucleus? Of all the eukaryotic organelles, the nucleus is the most critical. The mere presence of a nucleus is considered one of the defining features of a eukaryotic cell.7 ...

For hundreds of years before this discovery, scientists were puzzled by why heterochromatin clustered at the edge of the nucleus and how it was relevant to normal cell function. This recent discovery ...

Scientists have uncovered how a newly discovered gene, NEK1, in which mutations have been linked to ALS cases, disrupts the function of the motor neuron and causes it to degenerate and die.

Findings in nuclear physics theory have received several Nobel Prizes (1975-nucleus vibrations and rotations, 1963-nuclear shell model, 1949-meson exchange model of nuclear forces). Despite these ...

The electrons in an atom tend to occupy distinct shells. What about particles in the nucleus? The "magic numbers" of the isotope chart suggest that they also have a shell arrangement ...

Everything CCEA students need to know about the structure of the nucleus for GCSE Physics.
