Yes, blue eyes are a result of genetic mutation. Scientists have found out that a genetic mutation resulted in a reduced production of melanin,... View Article
A nonsense mutation is a point mutation, which leads to a change of a codon to the stop codon. It creates truncated and mostly non-functional... View Article
Genetic mutations can be harmful, neutral or beneficial. Mutation that causes large changes in the genome are mostly harmful and cause various... View Article
Deletion refers to missing genetic information from DNA. It can be a single nucleotide or a short stretch of DNA. Deletion is commonly caused due... View Article
Recombination in bacteria refers to transfer of genetic material from one cell to another. It can occur through three processes, they are:... View Article
The process of crossing over leads to recombination of alleles between non-sister chromatids of homologous chromosomes. During meiosis, crossing... View Article
DNA can get damaged by naturally occurring metabolites in the body such as reactive oxygen species, products of lipid peroxidation, etc. Various... View Article
Mutation changes the small sequence of DNA. Even a small change in DNA molecule leads to changes in the genes and the functional protein coded by... View Article
DNA damage can occur due to various factors such as ionising radiations, UV light, certain chemicals and also certain metabolites, which can... View Article
Recombination is the exchange of genetic information between two chromosomes or between two parts of the same chromosome. Recombination is mainly... View Article
Recombination occurs due to crossing over in meiosis, it ensures genetic diversity and inheritance of both maternal and paternal genomes.... View Article
Recombination is required for genetic diversity. It also ensures that offspring get both maternal and paternal genes from their grandparents. It... View Article
A mutation refers to the change in DNA of an organism, whereas evolution refers to change in the population over time. Mutation is one of the... View Article
Mutations are permanent changes in the sequence of DNA, which may be neutral, beneficial or harmful. Mutations are the driving force for... View Article
