The phenotype of an organism denotes its external appearance (size, color, intelligence, etc.). innocent genetics showed that genes gibe the transmission of phenotype from nonpareil generation to the next. Biochemistry showed that at bottom adept generation, proteins had a determining effect on phenotype. For galore(postnominal) years, however, the relationship amid genes and proteins was a mystery. Then, it was found that genes contain digitally encoded instructions that speak the synthesis of proteins. The crucial insight of molecular(a) biology is that hereditary culture is passed between generations in a form that is truly, not met aphorically, digital. intellectual how that digital code directs the concept of life is the goal of molecular biology.
