The overexpression of a gene tied to cell division and the structure and function of neurons may prevent and protect against cognitive decline in both mice and humans with Alzheimer's disease (AD), ...

Molecular biologists have long believed that the beginning of a gene launched the process of transcription—the process by which a segment of DNA is copied into RNA and then RNA helps make the proteins ...

A consortium of researchers has produced the largest and most advanced multidimensional maps of gene regulation networks in the brains of people with and without mental disorders. These maps detail ...

Whole genome duplication followed by massive gene loss has shaped many genomes, including the human genome. Why some gene duplicates are retained while most perish has puzzled scientists for decades.

Study of the principles of heredity in microbes, plants and animals. An integrated course in classical and contemporary molecular genetics dealing with topics that include the structure and function ...

Chromosomes are thread-like structures comprising DNA that are present inside the nucleus of every cell in the body. Specific segments of DNA are called genes. Every chromosome contains many genes, ...

Wood from forest trees modified for more cellulose or hemicelluloses could be a major feedstock for fuel ethanol. Xylan and glucomannan are the two major hemicelluloses in wood of angiosperms. However ...

Dyslexia is a common learning difficulty in which genes often play a role. How do genes associated with dyslexia relate to brain structure in the general population? In a large-scale study published ...
