1.The three components of a nucleotide are nitrogenous base, sugar and phosphate.
2.The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.
3.A mutation is defined as any permanent change to the genetic material. Mutation can be classified according to several criteria. (There are also non-permanent changes to the genetic material called epigenetic changes, like methylation of DNA bases.)
4.The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.
