  2. Somatic hypermutation - Wikipedia

    en.wikipedia.org/wiki/Somatic_hypermutation

    Somatic hypermutation (or SHM) is a cellular mechanism by which the immune system adapts to the new foreign elements that confront it (e.g. microbes).A major component of the process of affinity maturation, SHM diversifies B cell receptors used to recognize foreign elements and allows the immune system to adapt its response to new threats during the lifetime of an organism.

  3. Mutation - Wikipedia

    en.wikipedia.org/wiki/Mutation

    Spontaneous mutations occur with non-zero probability even given a healthy, uncontaminated cell. Naturally occurring oxidative DNA damage is estimated to occur 10,000 times per cell per day in humans and 100,000 times per cell per day in rats. [34]

  4. Somatic cell - Wikipedia

    en.wikipedia.org/wiki/Somatic_cell

    In cellular biology, a somatic cell (from Ancient Greek σῶμα (sôma) 'body'), or vegetal cell, is any biological cell forming the body of a multicellular organism other than a gamete, germ cell, gametocyte or undifferentiated stem cell. [1]

  5. Somatic cell nuclear transfer - Wikipedia

    en.wikipedia.org/wiki/Somatic_cell_nuclear_transfer

    Somatic cell nuclear transfer can create clones for both reproductive and therapeutic purposes. In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a laboratory strategy for creating a viable embryo from a body cell and an egg cell.

  6. Mutation (evolutionary algorithm) - Wikipedia

    en.wikipedia.org/wiki/Mutation_(evolutionary...

    Mutation is a genetic operator used to maintain genetic diversity of the chromosomes of a population of an evolutionary algorithm (EA), including genetic algorithms in particular.

  7. Mutation rate - Wikipedia

    en.wikipedia.org/wiki/Mutation_rate

    Recently reported estimates of the human genome-wide mutation rate. The human germline mutation rate is approximately 0.5×10 −9 per basepair per year. [1]In genetics, the mutation rate is the frequency of new mutations in a single gene, nucleotide sequence, or organism over time. [2]

  8. CDK13-related disorder - Wikipedia

    en.wikipedia.org/wiki/CDK13-related_disorder

    CDK13-related disorder, also known as congenital heart defects, dysmorphic facial features and intellectual developmental disorder (CHDFIDD), is a very rare autosomal dominant genetic condition characterised by congenital heart defects, intellectual disability and characteristic facial features.

  9. Mutation breeding - Wikipedia

    en.wikipedia.org/wiki/Mutation_breeding

    Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars.
