Gene redundancy - Wikipedia

Web‘Redundancy of parts’ primarily results from genetic duplication events, including duplications of individual genes or large regions of an organisms’ genome to provide a major source of genetic material for the evolution of new processes and functions. Gene redundancy most often results from Gene duplication. Three of the more common mechanisms of gene duplication are retroposition, unequal crossing over, and non-homologous segmental duplication. Retroposition is when the mRNA transcript of a gene is reverse transcribed back into DNA and inserted into the genome at a different location. During unequal crossing over, homologous chromosomes exchange uneven portions of their DNA. This can lead to the transfe… netflix wacc 2021 https://pdafmv.com
