E17. Gene mutagenesis is also used to explore the structure and function of proteins. For example, changes can be made to the coding sequence of a gene to determine how alterations in the amino acid sequence affect the function of a protein. Let's suppose that you are interested in the functional importance of a particular glutamic acid (an amino acid) within a protein you are studying. By site-directed mutagenesis, you make mutant proteins in which this glutamic acid codon has been changed to other codons. You then test the encoded mutant proteins for functionality. The results are as follows: Functionality (%) Normal protein 100 Mutant proteins containing Тугosine Phenylalanine 3 Aspartic acid 94 Glycine From these results, what would you conclude about the functional significance of this glutamic acid within the protein?
Q1: Why is an insertion or a deletion in a gene more likely to alter the protein product than a substitution, such as A for C, would? Q2: Which would you expect to have more impact on an organism: a point mutation as shown here, or the insertion or deletion of a whole chromosome (discussed in Chapter 8)? Q3: Which mechanisms in a cell prevent mutations?
A scientist creates fruit fly larvae with a mutation that eliminates the exonuclease function of DNA pol III. Which prediction about the mutational load in the adult fruit flies is most likely to be correct? The adults with the DNA pol III mutation will have significantly more mutations than average The adults with the DNA pol III mutation will have slightly more mutations than average The adults with the DNA pol III mutation will have the same number of mutations as average The adults with the DNA pol III mutation will have fewer mutations than average.

Q1 There are similarities and differences during regulation of gene expression in both prokaryotes and eukaryotes. Promoters, transcription factors and RNA polymerase are essential elements in transcription but their properties and function may differ. b) Hypothesize the transcription of eukaryotic genes using prokaryotic promoter with further explanation.
Q1. Predict the effects (on translation of coat gene and replicase gene) of the following mutations on phage R17 coat gene and replicase gene translation and explain the logic of your answers: a. An amber mutation (premature stop codon) six codons downstream of the coat gene initiation codon. b. Mutations in the stem loop around the coat gene initiation codon that weakens the base-pairing in the stem loop. c. Mutations in the interior of the replicase gene that cause it to base-pair with the coat gene initiation codon.
