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.

What is the ultimate source of genetic variation and the basis for the diversity of life on earth?
Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.
What surprised you about the process of DNA replication and protein synthesis?
One surprising aspect of DNA replication is the accuracy of the process, with very few errors occurring. In protein synthesis, the complexity and precision of the steps involved in translating the genetic code into functional proteins is also remarkable.
How often in the life of a cell does replication occur?
Cell replication can occur at different rates depending on the cell type. In general, cell replication can range from a few hours to a few days. For example, skin cells replicate every few weeks, while intestinal cells replicate every few days.
What binds to the prokaryotic chromosome to start DNA replication?
In prokaryotes, the DNA replication process is initiated by the binding of the DnaA protein to specific sites on the bacterial chromosome called DnaA boxes. DnaA protein helps in unwinding the DNA strands to enable replication to start.
Why is DNA replication important to organisms?
DNA replication is vital for the continuation of a species as it allows n organism to reproduce its genetic code and pass it along to the next generation. Without DNA replication, there would be no reproduction, so after all the current life dies out, there would be no more.

Are genetic mutations always harmful to the individual?
Genetic mutations are not always harmful to the individual. A few may be beneficial.
Which is more likely to develop adaptation to a changing ecosystem?
A population with few mutations will have more room in there genes to do mutations
Why is it easy for a virus to mutate?
Viruses mutate easily because they have a high mutation rate due to errors in their replication process. Additionally, viruses have short generation times which allows them to quickly accumulate mutations. Mutations can help viruses evade the immune system, adapt to new hosts or environments, and become more infectious.

Is it easy for breeders to produce mutants with desirable mutations?
Producing mutants with desirable mutations can be challenging and often requires selective breeding, genetic manipulation, or exposure to mutagens. While some mutations may occur naturally, it is not always easy for breeders to control which mutations appear or to ensure that they are beneficial. Additionally, ethical considerations and regulations may impact the process of producing mutants.
Where can one purchase DVD replication in bulk?
One can purchase DVD replication in bulk from the following sources: Easy Replication, Digi DVD, Disc Makers, Nationwide Disc, CDROM 2 GO, DVD Copying, to name a few.
How replication differ from translation?
well, since the previous person doesnt have a single working cell in his body, ill help u out Transcription- process that converts an mRNA message into a polypeptide. Translation- process of copying a sequence of DNA to produce a complementary strand of RNA. replication- process in which the RNA is duplicated
How many cats have ears?
All of them, with the possible exception of a very few (probably non-viable) mutations.
