Anyone who studied a little genetics in high school has heard of adenine, thymine, guanine and cytosine -- the A, T, G and C that make up the DNA code. But those are not the whole story. The rise of ...

Human Rho GTPases (of which there are 22 members) comprise a main branch of the Ras superfamily of small GTPases and GDP/GTP-regulated molecular switches. Rho GTPases are activated by the direct ...

The nucleotide sequences coding for murine complement component C3 have been determined from a cloned genomic DNA fragment and several overlapping cloned complementary DNA fragments. The amino acid ...

Despite the relevant role of models of nucleotide substitution in phylogenetics, choosing among different models remains a problem. Several statistical methods for selecting the model that best fits ...

Purines are heterocyclic bases. Simply put, these are closed ring structures comprised of at least two different kinds of atoms. Purines are one of three components of nucleotides; phosphate esters of ...

Comparison of Outcomes After Fluorouracil-Based Adjuvant Therapy for Stages II and III Colon Cancer Between 1978 to 1995 and 1996 to 2007: Evidence of Stage Migration From the ACCENT Database Although ...

A CRISPR system detects rare cancer mutations in blood with single-nucleotide precision, outperforming ddPCR through engineered RNA guides and isothermal amplification.

Restriction fragment length polymorphism (RFLP) is a technique invented in 1984 by the English scientist Alec Jeffreys during research into hereditary diseases. It is used for the analysis of unique ...

The information that is carried by the genetic code provides a set of "instructions" for "building" and "maintaining" a living organism. A useful analogy might be to think of the genetic code being ...

On August 24, 2025, the 23rd International Congress of Nutrition (ICN) convened in Paris, France, under the theme "Sustainable Food for Global Health." As the premier platform in nutritional science, ...
