Why do cells have a plasma membrane
<u>Answer:</u>
Point mutations occur when only one nucleotide is altered affecting only one location or point of the DNA strand.
While Frameshift mutations are caused by the deletion or insertion of a number of nucleotides.
These altered nucleotides affect the triple nature of gene expression disturbing the whole reading frame. All the codons after mutation are different translating a completely different protein. That's why frameshift mutations cause more problems than point mutations.
When tryptophan is not available in the environment, the trp repressor is inactive. Therefore, RNA polymerase can bind to the promoter.
