In the race of evolution, innovating is certainly necessary, but recycling existing genes is sometimes more efficient. Indeed, organisms that are very distant from each other can exchange a ...

De novo gene evolution describes the process by which entirely new genes originate from previously non-coding DNA rather than from the duplication and divergence of existing genetic material. This ...

Olfactory receptor (OR) genes, representing the largest multigene family in mammalian genomes, have undergone extensive evolutionary modifications characterised by dynamic patterns of gene duplication ...

The evolution of life is marked by the emergence of novel traits, driven by the birth of new genes. This process of genetic innovation underpins adaptation, shaping the survival and success of species ...

A genomic atlas of Nematostella vectensis reveals how primitive animals created multiple cell types millions of years ago, ...

Findings suggest that new genes can form by repurposing fragments of ancestral genes while incorporating entirely new coding regions (the protein-coding parts of the DNA). This innovative concept ...

The dissolution of protein coding genes in molecular biology / T. Fogle -- The differential concept of the gene: past and present / S. Schwartz -- Gene concepts and genetic concepts / F. Gifford -- ...

Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures. This ability to alternate ...

Evolution of the mouse [Beta] globin complex locus / M.H. Edgell, S.C. Hardies, B. Brown, C. Voliva, A. Hill, S. Phillips, M. Comer, F. Burton, S. Weaver, and C.A ...

“This DNA repair and replication activity supports a fascinating mechanism called premeiotic endoreplication, a process through which the snake duplicates its chromosomes before dividing them, ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...
