How does ultraviolet light kill bacteria?
UV light causes dimerisation between Cytosine bases in DNA (causing it to mutate). As bacteria only have small genomes, mutations will have a lethal effect a lot more commonly than if it happened to a person.
Two causes of mutation?
Two types of mutations are Point Mutations and the other is Frameshift Mutations. Piont mutations include; deletions, insertions, and substitutions. These mutations casue a slight change in the amino acid usually resulting in a change in one amino acid. The second type, frameshift mutations involve many changes and almost always results in many changes in the codons.
How do mutations occur in an organism?
In the base sequence of the DNA part of the DNA changes which causes a change in the whole DNA which is called a mutation.
How do your white blood cells disarm foreign bacteria?
The WBC's (White Blood Cells) enter the area with the bacteria. When the reach, they give off antibodies, which then go and attach to the bacteria. This stops the bacteria. Then the macrophages, or the largest WBC's devour the bacteria along with the antibodies. A chemical in the macrophage causes the bacteria to dissolve.
Are mutations in the DNA sequence gene transient changes?
Successful mutations will persist. Mutations usually occur during replication. Some mutations will flourish depending on environmental factors.
When was Mutations of Bacteria from Virus Sensitivity to Virus Resistance created?
Mutations of Bacteria from Virus Sensitivity to Virus Resistance was created in 1943.
Is 'mutations are beneficial to organisms' a true statement about mutations?
Not always. Mutations can have either beneficial, neutral, or harmful effects on organisms. Whether a mutation is beneficial or not depends on how it impacts the organism's ability to survive and reproduce in its environment.
How did scientists produce oil eating bacteria?
Inducing mutations in bacteria
Why would humans be interested in introducing mutations into bacteria?
Introducing mutations into the bacteria is called "engineering" the bacteria. it allows bacteria to be developed that can be put to work for useful purposes (devouring oil spill gunk, as one example), and there are hundreds of other uses for engineered bacteria, too.

What causes mutations that ends in an n?
Radiation.
What causes variations in numbats?
Mutations in a numbat's DNA.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
Which causes strep throat anthrax and tetanus?
Bacteria causes anthrax.
Fill in the blank Environmental causes of mutations are called?
mutagens
What is salmonella typhi?
It is the bacteria that causes Typhoid fever. It is the bacteria that causes Typhoid fever.
What are some ways that mutations in some living things are helpful to those organisms but harmful to humans?
Mutations in bacteria that confer antibiotic resistance help the bacteria survive and thrive in their environment, but can be harmful to humans if these bacteria cause infections that are difficult to treat. Similarly, mutations in insects that confer resistance to pesticides help them survive, but can be harmful to humans as it makes pest control more difficult.
