Study explains long-standing question of why Huntington’s disease symptoms typically do not appear until midlife even though ...

In a nutshell Scientists discovered that random DNA mutations don’t just cause local damage, they trigger widespread changes ...

And the DNA mutations found in the astronauts are very ... or tinkering with something on his computer.

This DNA has suffered a mutation, either through mis-copying (when its parent cell divided), or through the damaging effects of exposure to radiation or a chemical carcinogen.

As opposed to gene-level mutations, mutations that alter longer stretches of DNA (ranging from multiple genes up to entire chromosomes) are called chromosomal mutations. These mutations often have ...

Here’s how it works. Scientists have created a mega-database revealing how half a million different DNA mutations generate errors in proteins in humans. The researchers hope that the database ...

Scientists at the Broad Institute of MIT and Harvard, Harvard Medical School, and McLean Hospital have discovered a ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

The rate of molecular evolution is measured by using computer algorithms that estimate the number of substitutions (fixed mutations) per unit time in DNA sequences. This process is aided by using ...
