Can silent mutations change a phenotype

WebA silent mutation is caused by a base substitution that does not change the amino acid sequence, and therefore will not affect the phenotype. For example, substituting the A with G still results cysteine. b. More than one codon can code for the same amino acid. For example, six different codons code for leucine. If the new codon still codes for ... Webphenotype (advanced version only). Students will be able to: • transcribe and translate a DNA sequence. ...
