Relationship between Genotype and Phenotype Molecular Basis for Relationship between Genotype and Phenotype genotype DNA DNA sequence transcription RNA translation amino acid sequence protein function phenotype organism

Gene Sites Sensitive to Mutation null if splice junction is affected no effect if mutation is in the middle of the intron or not the branch point Refer to Figure 2-13, Griffiths et al., 2015.
