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 ...

This discovery laid the foundation for understanding the structure and function of genes. Within a gene, there are coding regions called exons, which contain the information for protein synthesis, and ...

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 ...

Transposons, also known as jumping genes or mobile genetic elements as they can replicate and reinsert themselves in the ...

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.

Each gene tells a cell to make a specific molecule ... such as insulating the wires, supporting the structure and clearing out debris. Until recently, scientists could only study bulk tissue ...

Sequences within each gene's repetitive region—its TIGR arrays ... They have determined the molecular structure of one of the Tas proteins they found to work in human cells, and will use ...

A rapid experimental genetic test can help guide the hands of surgeons as they delicately remove tumors from patien ...

Researchers from the NIHR Moorfields Biomedical Research Centre and University College London have found that gene therapy improved visual acuity and preserved retinal structure in young children ...
