The dna sequence of a portion of a gene in a wild-type organism is ttaccatattcacco and the corresponding peptide sequence is leu pro tyr ser pro. the corresponding gene fragment in a phenotypic variant of the organism is ttaccatatctcaccc and the peptide sequence is leu-pro-tyr-leu-thr. this is an example of a(n) mutation (type) resulting in a mutation (effect)
a. insertion, missense
b. base substitution, missense
c. base substitution, silent
d. deletion, missense
