During replication, transcription and translation there can be a mistake made in the bonding of complementary bases. These mistakes lead to mutations. There are three main types of mutations: point mutations, insertion, and deletion mutations. In this activity, you will use the mRNA and amino acid sequences to identify the mutation that occurred and the likely effects of the mutation.
