A genetic mutation of the H5N1 bird flu virus — a mutation associated with increased infectiousness and disease severity — ...

Nonetheless, certain other mutations can greatly impact the life and function of an organism. For example, somatic mutations that affect cell division (particularly those that allow cells to ...

In point mutations, one base pair is changed. The human genome, for example, contains over 3.1 billion bases of DNA, and each base must be faithfully replicated for cell division to occur.

When the COVID-19 pandemic first began, we saw how quickly the SARS-CoV-2 virus evolved. New variants emerged with mutations ...

SACRAMENTO, the United States -- Scientists are sounding the alarm about a concerning genetic mutation of the H5N1 bird flu virus, recently identified in four dairy cow herds, as this mutation could ...

That makes knowing the rate at which it occurs crucial to the study of evolutionary biology. Mutation rate figures into all kinds of calculations. For example, the “molecular clocks” that evolutionary ...

Variation is the differences in the characteristics of organisms. It can be caused by the genes an individual inherits or the environment it lives in. Extensive genetic variation is contained ...

A gene known as HbS was the center of a medical and evolutionary detective story that began in the middle 1940s in Africa. Doctors noticed that patients who had sickle cell anemia, a serious ...

Mutations could cause different genes to be switched on or off, and this could create a different or faulty protein to be synthesised. For example, if the protein is an important enzyme ...

The various mutations that occur in cancer cells have ... The results could unravel, for example, cancer onset processes and regional variations, they said. The research results were published ...
