Consequently, proteins made from genes containing frameshift mutations are nearly always nonfunctional. Figure 11.5. 1: Mutations can lead to changes in the protein sequence encoded by the DNA. Exercise 11.5. 2
WebSep 27, 2024 · These studies established that the frameshift-prone tRNA decoded the mRNA in the unshifted or zero frame, thus indicating that the move into the frameshift must be in a postdecoding step. However, the point at which the shift occurs after the tRNA-mRNA pair leaves the A site is not clear. WebQuestion: Exercise 2 Frameshift and Point Mutations In this exercise you will translate a sequence of RNA before and after creating point and frameshift mutations within the sequence. Procedure Examine the mRNA sequence in Data Table 2. Determine the amino acids coded by the mRNA strand using the coding chart in Figure 5.
