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.

What is the result of a mutation occurring in a suppressor gene?
A mutation in a suppressor gene can lead to the loss of its normal function, resulting in the inability to suppress the growth of cancer cells or prevent mutations from occurring. This can contribute to the development and progression of cancer.
Why is the replication process is a source of few mutations?
Some mutations are due to errors in DNA replication. During the replication process, DNA polymerase chooses complementary nucleotide triphosphates from the cellular pool. Then the nucleotide triphosphate is converted to a nucleotide monophosphate and aligned with the template nucleotide. A mismatched nucleotide slips through this selection process only onece per 100,000 base pairs at most. The mismatched nucleotide causes a pause in replication, during which it is excised from the daughter strand and replaced with the correct nucleotide. After this so-called proofreading has occurred, the error rate is only one per 1 billion base pairs.
If a cell has pairs of homologous chromosomes, what process is likely occurring within the cell?
If a cell has pairs of homologous chromosomes, the process likely occurring within the cell is meiosis.
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.
When a muscle contracts, what physiological process is occurring within the body?
When a muscle contracts, the physiological process occurring within the body is the shortening of muscle fibers, which results in the generation of force and movement.
How animal will prevent mutation?
Animals cannot prevent mutations from occurring, as mutations are random changes in the DNA sequence that happen naturally during cell division. However, organisms have evolved systems like DNA repair mechanisms and checkpoints during cell division to minimize the impact of mutations. Additionally, natural selection acts to remove harmful mutations from a population over time.
What is the result of a mutation occurring in a suppressor gene?
A mutation in a suppressor gene can lead to the loss of its normal function, resulting in the inability to suppress the growth of cancer cells or prevent mutations from occurring. This can contribute to the development and progression of cancer.
What is a naturally occurring anti-coagulant?
Blood group O
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.
A molecular clock relies on the repeating process of?
A molecular clock relies on the repeating process of DNA mutations occurring at a relatively constant rate over time. By measuring the differences in DNA sequences between species or individuals, scientists can estimate when they diverged from a common ancestor. This provides insights into evolutionary relationships and the timing of key events in evolutionary history.
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.
Is the difference between germ line and somatic 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 is occurring in the illustration below?
I'm unable to see the illustration you mentioned, but if you describe it, I can help explain the process occurring in it.
Can you prevent a tornado from occurring?
No. There is no way for us to prevent tornadoes. We cannot control nature.
What are two ways to prevent conflicts from occurring?
Sometimes you can prevent conflicts by walking away from the conflict.
What process is occurring that makes breath visible in cold?
The process of condesation
