A mutation in the regulator gene of the lac operon can disrupt the production or function of the repressor protein that normally inhibits the operon in the absence of lactose. If the mutation leads to a non-functional repressor, the operon may be constitutively expressed, resulting in unnecessary enzyme production even when lactose is not present. Conversely, a mutation that enhances repressor function could prevent the operon from being activated when lactose is available, impairing the cell's ability to utilize lactose as an energy source. Overall, such mutations can significantly impact the regulation of gene expression in response to environmental changes.
What else can I help you with?
What is a mutation you might have but not know about?
substitution
What does a mutation have to do with human DNA?
A mutation usually is associated with the change in DNA pattern. Depending on the mutation (which can occur for various reasons such as radioactivity or birth defect), it might be deadly or harmless.
What type of mutation is a point mutation?
A point mutation is when 1 base pair is swapped out for another one... so instead of an A you might find a C... or T... or G. Also an insertion or deletion of a base pair A mutation of a single point :)
What is mutation and how might is affect an organism?
A mutation is a change in the DNA sequence of an organism's genome, which can occur due to errors during DNA replication or as a result of environmental factors. Mutations can be beneficial, neutral, or harmful; beneficial mutations may confer advantageous traits that enhance survival or reproduction, while harmful mutations can lead to diseases or reduced fitness. The effects of a mutation depend on its nature, location in the genome, and environmental context. Overall, mutations are a key driver of genetic diversity and evolution.
How might a point mutation in a gene affect the reasulting protein?
point mutations include substitutions insertions and deletions of a single nuceotide in DNA. CONSIDER: insertions and deletions have a greater effect on proteins that do substiutions because insertions and deletions affect every amino acid that is specified by the nucleotides that follow the point of mutation CONSIDER: a substitution affects a single amino acid a change in more than one amino acid is more likely to alter the ability of the protein to function narmally than is a change in a single amino acid CONSIDER: follow me on twitter @Rocco_Gone_Ham

How can you detect neutral mutation on molecular level?
"Neutral" isn't a molecular-level concept. A neutral mutation is one that doesn't affect the fitness of the organism; fitness is depending on the environment. For instance, a mutation that's neutral when nutrients are plentiful might become positive or negative if a particular nutrient becomes rare.

What might happen if such a mutation occurred in persons DNA?
The person might end up getting cancer.
What might happen if a mutation occurs in a person's DNA?
The person might end up getting cancer.
How might a point mutation in a gene affect the resulting protein?
A point mutation in a gene can change a single nucleotide in the DNA sequence, which can lead to a different amino acid being incorporated into the protein during translation. This can alter the structure and function of the protein, potentially affecting its ability to perform its normal role in the cell.
Why are somatic mutations generally less important than germ mutations?
Because the somatic mutation only produces the color of the iris of the eye. The germ mutation is in charge of the cell which will produce a gamete. It may be passed onto the offspring. So the somatic mutation isn't as important as the germ mutation.
How might biologist determine whether a mutation has occurred and if so what type of mutation is it?
The comparison between the DNA sequence of normal DNA to the mutated DNA will be made. The type of mutation will be revealed during the base sequence.

Should the regulator on your barbecue be hissing?
No. It sounds like there might be a gas leak.
