Transfer RNA (tRNA) converts the master code (on DNA) which is now on mRNA into a protein. It makes sure that the codes match.

What are two functions of DNA polymerases during DNA replication?
DNA Polymerase has 2 main functions. The first is replication, or creating the new DNA strand from the template it has been given. The second is proofreading the new strand after it has been created to make sure it had been copied correctly.
What is DNA polymerase proofreading?
Proofreading means to read something & mark corrections in it. It could also be called editing. ChaCha on!
List the enzymes involved in replication and describe their function?
Topoisomerase is the enzyme that relieves tension to the DNA molecule by nicking and cutting certain placed on the phosphate backbone. Helicase is the next enzyme that is involved in "unzipping" the DNA to produce two single strands of DNA. RNA polymerase lays down the RNA primer DNA polymerase III uses the RNA primer to start laying down new nucleotides on the single strand of DNA. DNA polymerase I replaces the RNA primer with DNA DNA ligase creates joins the backbone of the newly formed DNA strands
What checks DNA for error?
DNA fingerprinting
Principle enzyme involved in DNA replication?
DNA Polymerase.
What molecule will proofread the new DNA strands?
RNA polymerase is the enzyme that connect the new nucleotides together and proofreads them.
What enzyme connects the new nucleotide together and proofreads them?
RNA polymerase is the enzyme that connect the new nucleotides together and proofreads them.
What enzymes check for mistakes in replication?
proof reading enzymes, e.g. the exonuclease domain of some DNA polymerases.
How do your cells prevent errors in replication?
Things that help prevent DNA errors:Complementary base pairing reduces errors.DNA polymerase checks the DNA for errors.Each base can attach to only one other type of base.
What do you call a person who proofreads books?
An editor
What do you call a person who proofreads?
proofreader or editor

What is the difference between mismatch repair and nucleotide excision repair?
The differences are as follows: Mismatch repair DNA polymerase is the enzyme that is responsible for DNA replication. As it copies the the DNA, it can make mistakes. So, when the DNA is copied, mismatch repair proofreads it and makes sure that the nitrogenous bases are correct. If they aren't, then it will take out only the base. However, if the mismatch repair is not functioning, then humans can get some form of cancer. Excision repair This mechanism is caused by UV rays or some sort of harmful chemical. Excision repair fixes what portion may have been destroyed by these mutagens. It takes the entire strand and replaces it with a new one. However, if this mechanism doesn't work, then forms of skin cancers arise.
What reduces errors in DNA replication?
There are an average of 6 errors for every cell division, most of which either occur in the 95% percent of DNA that does not code for proteins or are relatively unharmful substitution mutations.

What is a person called who critiques and proof reads?
A person who critiques and proofreads is typically called an editor. Editors review written content for errors in grammar, punctuation, spelling, and style, offering feedback and suggestions for improvement.
