| In the case of electrons, nine alleles had point-like mutations and three had rearrangements. |
| In any case, these low estimates are in at least qualitative agreement with other evidence suggesting the recessivity of beneficial mutations. |
| We analyzed gene mutations in patients who died of thrombotic events, using multiplex allele-specific polymerase chain reaction amplification. |
| These rates are greater than expected for additive or multiplicative effects of the single mutations. |
| Like most RNA viruses they accumulate mutations very fast, and the way the virus RNA replicates itself facilitates frequent recombination. |
| A new study reveals for the first time how gene mutations lead to the inherited form of amyotrophic lateral sclerosis, or Lou Gehrig's disease. |
