Student ID = mc170404399 ASSIGNMENT NO : 2 Q 1 . Differentiate between somatic and germline mutations ? Give at least two examples of each. In biology, a mutation is the lasting modification of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations results from faults during DNA replication or other types of damage to DNA which then may have erroring repair or cause an error during other forms of repair, or …show more content…
Mutations in genes can either have no effect, alter the product of a gene, or preclude the gene from functioning properly or completely. SOMATIC MUTATION : A change in the genetic structure that is not inherited from a parent, and also not passed to offspring, is called a somatic mutation. Somatic mutations are not inherited because they do not affect the germline. These types of mutations are commonly motivated by environmental reasons , such as ultraviolet radiation or any vulnerability to certain harmful chemicals, and can cause diseases include cancer.A somatic mutation is gained mutation, which present in a single body cell of an individual after its conception. Somatic mutations pass merely to the descending cells of the mutated cell. However, only a sphere of the mutated individual accepts the somatic mutation. Hence , somatic mutations makes individuals with somatic mosaicism, consisting the cells with various genotypes within the same
