Gene mutation include base substitution, deletions or additions. Base additions or deletions usually have a very significant effect on the structure, and therefore the function, of the polypeptide that the allele codes for. Base additions or deletions always have large effects, because they alter ...
This tutorial looks at the mutation at the gene level and the harm it may bring. Learn about single nucleotide polymorphisms, temperature-sensitive mutations, indels, trinucleotide repeat expansions, and gene duplication.
What genetic mutation causes tritanopia? On the molecular level, what exactly is a mutation? What genetic mutation causes hypercholesterolemia? Which type of mutation occurs in reproductive cells and can be passed to offspring? What is the difference between genetic drift and mutation?
Patches of tissue can also be ablated, albeit at random locations, by generating clones of tissue that are mutant for a temperature-sensitive cell-lethal mutation such as sec5ts [21]. As with fragmentation, genetic ablation usually results in localized regenerative growth characterized by an ...
Genetic control of mosquito vector populations is a key tool for reducing malaria infections. Here, the authors develop a self-limiting strategy where CRISPR-Cas9 is inherited exclusively on the Y chromosome and drives an autosomal mutation resulting in dominant sterility in female offspring. ...

Genebanking, the process of preserving genetic resources, is a central practice in the modern management of crop genetics, especially for the species used
Genetic variation, which is generated by mutation, recombination and gene flow, can reduce the mean fitness of a population, both now and in the future. This ‘genetic load’ has been estimated in a wide range of animal taxa using various approaches. Advances in genome sequencing and computatio...
Genetic instability, a heritable increase in the rate of genetic mutation, accelerates evolutionary adaptation1 and is widespread in cancer2,3. In mammals, instability can arise from damage to both copies of genes involved in DNA metabolism and cell cycl
