EXPORT MECHANISM: The tRNA must mature inside the nucleus before export. tRNAs are aminoacylated, and only tRNAs charged with an amino acid are exported efficiently. Export occurs when the tRNA is ...

This narrated animation illustrates the process of protein synthesis, starting with chromosomal DNA inside the cell's nucleus. A gene is transcribed into messenger RNA, which leaves the nucleus and ...

Rush hour never ceases at the nucleus’ border. Gene products begin their lives in the nucleus as strands of mRNA that ship out into the cytoplasm, where they serve as templates for protein synthesis.

What exactly is the relationship between genes and proteins, and what part did black urine play in revealing this mysterious and crucial connection? RNA is found in both the nucleus and the cytoplasm.

Texts without spaces are not very legible, as they make it very difficult for the reader to identify where a word begins and where it ends. When genetic information in our cells is read and translated ...

In all eukaryotic organisms, genetic material is stored in the cell nucleus in the form of DNA. In order to be used, this DNA is first transcribed into messenger RNA in the cell cytoplasm, then ...

Light can be used to control the transport of proteins from the cell nucleus with the aid of a light-sensitive, genetically modified plant protein. Biologists working in the field of optogenetics have ...

It is widely held that long-term memories are established by consolidation of newly acquired information into stable neural representations, a process that requires protein synthesis and synaptic ...

Cells express their genes by converting the genetic message into protein. This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the ...

Ribosome Assembly: New research shows that neurons not only synthesize proteins locally near synapses. They can also assemble ribosomes at synapses. Dynamic Regulation: Local ribosome maturation ...

American Scientist (ISSN 0003-0996) is an illustrated bimonthly magazine about science and technology. Each issue is filled with feature articles written by prominent scientists and engineers, ...
