WebFeb 16, 2016 · Transcription errors were enumerated for B. aphidicola, an insect endosymbiont recovered directly from its aphid host, Acyrthosiphon pisum. B. aphidicola cells were recovered from the filtrate by centrifugation. Transcription errors occurring in the genome of C. rudii, another insect endosymbiont, were determined from a pooled sample … WebPoint mutations usually take place during DNA replication. DNA replication occurs when one double-stranded DNA molecule creates two single strands of DNA, each of which is a template for the creation of the complementary strand. A single point mutation can change the whole DNA sequence. Changing one purine or pyrimidine may change the amino ...
