Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...

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.

Scientists from Singapore and Germany have identified that the proteins lamin A (Lmna) and lamin B receptor (Lbr) are essential for holding silent genes in their correct position at the edge of the ...

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 ...

To decipher the structure of the F-actin nucleus, researchers used a dual-mutant strategy. They created two mutant versions of actin monomers that could bind together to form a nucleus but could not ...

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. The viral ...
