. You obtain the DNA sequence of a mutant of a 2-kb genein which you are interested and it shows base differencesat three positions, all in different codons. One is a silentchange, but the other two are missense changes (they encode new amino acids). How would you demonstratethat these changes are real mutations and not sequencing errors? (Assume that sequencing is about 99.9 percent accurate.)
MAKE CONNECTIONS Although the proteins that cause theE. coli chromosome to coil are not histones, what propertywould you expect them to share with histones, given theirability to bind to DNA (see Figure 5.14)?

In bacterial genes, as soon as any partial mRNA transcriptis produced by the RNA polymerase system, the ribosome assembles on it and starts translating.
