Let’s say you have a protein that normally contains the codon 5’ ucu 3’. After a mutation occurs this codon now reads 5’ acu 3’. What kind of mutation occurred?.

Answer: TransversionExplanation:The mutation occured within the DNA so we have to consider what the original DNA template was for that first codon position. U in RNA is complementary to A in DNA (U is used in place of T for RNA).The mutated codon has an A in place of the U so that means that the mutated DNA contains a T.An A --> T mutation is called a transversion because it is going from a purine to a pyrimidine.
