The question “What is a gene?” has bothered geneticists for fifty years. Recent work with a small bacterial virus has shown how to split the gene and make detailed maps of its internal structure ...

What have we learned about RNA structure and function so far ... Prokaryotic organisms contain one type of rRNA gene that encodes three distinct RNA species: the 23S, 5S, and 16S rRNAs.

despite an awareness that the scope and complexity of the task defy a fully systematic approach. Speakers agreed that examining the three-dimensional (3-D) structure of gene products is a promising ...

In fact, each gene in cellular DNA contains the code for a unique protein structure. Not only are these proteins assembled with different amino acid sequences, but they also are held together by ...

(Getty Images) Two new landmark studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published March 3 as ...

A team of researchers has identified a mechanism that regulates the production of two different proteins from the same gene.
