No. The errors in copying dna gives rise to mutations within an organism, which is the key driver of evolution. The mutations which benefit the organism in surviving its environment make it more likely to reproduce, thus spreading it through the population. Mutations that arent beneficial are by the same process less likely to be spread. However sexual selection can override this general rule. As in the case of the peacock and its amazing tail. Although this tail is technically a hinderance to the peacocks everyday life, peahens have, by selecting males with the best tails, effectively designed the tail over many generations.

Why is it more important to check for errors during replication than during protein synthesis?
Because if an error is made during protein synthesis, the result is at worst one bad protein. If an error is made during DNA replication, that error will persist for the entire lifespan of that cell and be inherited by every daughter cell it produces. Should the error prove deleterious, the effects can be catastrophic for the cell or the organism. For example, if an error occurs in a protein coding segment of DNA, it is possible that every protein that locus generates will now be defective.
What holds DNA strands apart during replication?
What prevents the wrong nucleotide from being added to the new strand during DNA replication? DNA polymerase 3 and DNA polymerase 1 can become what is known as exonucleases. an exonuclease can go back and "proofread" the replicated DNA and if there is a mistake, then everything beyond that incorrect nucleotide is removed and the DNA polymerase 3 will re-replicate from the bad point on. the protein p53 holds the cell in the G1 and S phase of replication which allows more time for proof reading the replicated DNA
Is DNA fingerprinting good or bad?
good
Why do new copies of DNA have to be similar to the original strand?
New copies of DNA have to be identical to the original strand so that the cells can function properly. If mistakes are made in DNA replication, it could cause a mutation to occur. In body cells, that means the possibility of tumors, including cancer. In gametes (sperm and egg cells), this could mean are very harmful genetic disorder, or it could be so bad that the organism produced by fertilization may not be able to survive.
What is bad radiation?
Radiation is bad for us because most of the types of electromagnetic radiations are high in energy. This high energy waves can cause damage to our cells. Prolonged exposure to gamma rays can be bad for health.
What will occur if a DNA polymerase makes a mistakeduring DNA replication?
It do occur during the replication. DNA polymerase has a proof reading activity that can correct the wrong base in the sequence. If the mutation persist it may cause any bad effect or stay neutral in case of silent mutation.
What prevents the separated DNA strands from reattaching to one another during during DNA replication?

Will DNA unwind as a result of a mutation?
after mutation two kinds of effect may take place. good or bad. in case of plant good yieldin, big fruits etc.. are found but in man usually it make a bad effects. klinfilter syndrome, sikkle cell aneamea are some of such diseases.
What are bad sector errors?
what are bad sectors errors
What are the similarities photocopying a document similar to DNA replication?
similarly, the cell uses vital DNA "master plan" to prepare RNA "blueprints". The DNA molecule stays safe in the cells nucleus while RNA molecules go to the protein building sites in the cytoplasm- ribosomes.

Why is it important for DNA to be replicated before cell division?
so it won't die out
