Web1 mrt. 2024 · The two main steps in gene expression are transcription and translation. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination. WebCrop improvement relies on genetic variation, which is synonymous with DNA variation. Mutations are the source of genetic variation that is the driver for trait improvement. In general, mutations are rare events, and most are deleterious and get selected against during the course of evolution. However, occasionally mutations create genetic ...
