A reseаrcher is studying а pоpulаtiоn оf E. coli bacteria that have been exposed to a chemical mutagen. After several generations, some bacteria show noticeable changes in their phenotype: a few colonies have altered colony size, some show changes in color, and others display resistance to antibiotics that the parent strain was sensitive to. The researcher wants to determine whether these changes are due to mutations in specific genes and whether the mutations are heritable. Which type of mutation could cause a single nucleotide change that results in a different amino acid in a protein? [color1] A mutation results in a premature stop codon in a key metabolic gene. What is the most likely effect on the protein? [color2] If the researcher sequences the DNA of antibiotic-resistant colonies, which type of mutation is most likely responsible? [color3] Why is it important to distinguish between somatic and heritable mutations in bacterial populations? [color4] A frameshift mutation occurs due to the insertion of one nucleotide in a coding sequence. What is the likely impact on the protein? [color5]
