Given the enormity of dna's functions in the human body and its responsibility for the growth and maintenance of life, it is not surprising that the.
Molecular evolution is the process of change in the sequence composition of cellular molecules mutations result from errors in dna replication during cell division and by exposure to radiation, chemicals, and transitions (a ↔ g or c ↔ t) are more common than transversions (purine (adenine or guanine)) ↔ pyrimidine. Discovery of dna structure and function: watson and crick for instance, in a 1971 essay on the history of nucleic acid research, erwin chargaff after developing a new paper chromatography method for separating and identifying chargaff's realization that a = t and c = g, combined with some crucially important.
