Genetic mutation

Researchers from Iceland look at how parents' age and sex influences new genetic mutations in children that may lead to rare medical conditions.

In a new paper published in Cell, Harvard researchers exploring the genetic features that help make the knee possible found that the regulatory switches involved in its development also play a role in a partially heritable disease.

Though previously used in immortal cells grown in labs, this is the first time these CRISPR tools are rejiggered for cells from our bodies.

Mutations Are heritable changes in genetic information Have two major types: Chromosomal mutations Point mutations Can be harmful or beneficial

A mutation is an unpredictable change in the genetic material of an organism. Gene mutation: change in the structure of a DNA molecule, producing a different allele of a gene. Chromosome mutation: changes in the structure or number of whole chromosomes in a cell. Sources/ mutagens : increase chances of a mutation occuring - random - environmental factors (ionising radiations alpha, beta, gamma; UV radiation; chemicals) Gene mutations Types: base substitution base addition base deletion…
