DNA polymerase checks DNA for errors.
DNA polymerase checks DNA for errors by breaking the hydrogen bonds between the paired nitrogen bases in the DNA molecule. This causes the molecule to separate into two individual strands.

∙ 8y agoBoth Prokaryotes and Eukaryotes have proofreading mechanisms built in that read newly synthesized DNA strands and check for mutations. Then by utilizing exonucleases and ligases they can cut and remove the mutated base pair and religate the DNA (join the ends back together again). One way you could help to lower the mutation rate of an organism would be to make sure that genes coding for things like DNA polymerase III (Eukaryotes) or DAM Methylase (Prokaryotes) are not mutated, because these are proofreaders in the cell and if they don't function properly you will see a ton of mutations.

∙ 13y agoBecause DNA damage occurs spontaneously and as a result to ubiquitous environmental agents, most organisms possess some capacity to repair their DNA and DNA is the only macromolecule which IS repaired by cells. We can divide "repair" mechanisms into 3 categories:
damage reversal--simplest; enzymatic action restores normal structure without breaking backbone
damage removal--involves cutting out and replacing a damaged or inappropriate base or section of nucleotides
damage tolerance--not truly repair but a way of coping with damage so that life can go on

How does polymerase prevent mutations?
It checks DNA for errors during replication.
What is the difference between somatic and germ line mutations?
A mutation occurring in a germ cell is heritable 50% of the time. Somatic cell mutations only affect the individual cell and its progeny produced by mitosis. Somatic cell mutations cannot be passed on to the organism's offspring.
What two process can led to inherited variation in population?
Mutations and emergent properties.
How will mutations be useful in achieving your goal color?
If the mutations can be helpful to reach the color goal it may help the process go faster or may introduce a color that is the exact same color as your goal.
Why is it so difficult to prevent pneumocystis pneumonia infections from occurring in AIDS patients?
This is a member of the normal microbiota for most people, and it is difficult to prevent contact with it.
Are mutations still occurring in organisms in modern times?
Yes. Mutations are random copying errors much of the time and that never stops because replication is not perfect.
How does polymerase prevent mutations?
It checks DNA for errors during replication.
How can temperature either help fusion to occur or prevent fusion from occurring?
How can temperature either help fusion to occur or prevent fusion from occurring?
Are there any birth control pills iuds shots that prevent fertilization not implantation?
Hormonal forms of birth control (the Pill, Depo-Provera shots, the Nuva ring, the Patch) prevent eggs from being released, and therefore prevent fertilization from occurring. Condoms (male and female) also prevent fertilization from occurring if they are used properly. The IUD prevents implanation after fertilization by a process not fully understood.
A molecular clock relies on the repeating process of?
Mutations
Can you prevent a tornado from occurring?
No. There is no way for us to prevent tornadoes. We cannot control nature.
What is the difference between somatic and germ line mutations?
A mutation occurring in a germ cell is heritable 50% of the time. Somatic cell mutations only affect the individual cell and its progeny produced by mitosis. Somatic cell mutations cannot be passed on to the organism's offspring.

What process changes adds or removes information from the genome?
Mutations
What are two ways to prevent conflicts from occurring?
Sometimes you can prevent conflicts by walking away from the conflict.
Why do you use contraceptives?
Contraceptives are used to prevent pregnancy from occurring.
What process is occurring that makes breath visible in cold?
The process of condesation
