What does it mean to say that there is a proofreading function in DNA replication?

It basically means that because when a DNA double helix 'unzips' and free-floating nucleotides go to pair with the base pairs, if their was a mistake, it will be fixed.
For example- say this is what the DNA 'read' originally
A - T
A - T
C - G
G - C
T - A
G - A
The last pair is incorrect, because Guanine and Adenine don't pair up, well, when it unzips and they're separated, C will bond with G, and T will bond with A, that way the pairs are now correct and that the pair isn't re-replicated.

What are enzymes that have a proofreading role in DNA replication?
DNA polymerases
DNA is copied during a process called?
Replication.
During replication what is the function of the enzyme DNA polymerase?
DNA polymerase are enzymes that form bonds between nucleotides during replication.
What does DNA polymerase 1 do?
DNA polymerase 1 is involved in replication when proofreading and repairing of the DNA sequence as well as removal of RNA primers placed by primase so that DNA polymerase 3 can successfully attach the complementary strand of DNA
What are the areas on DNA where replication occurs called?
DNA replication begins in areas of DNA molecules are called origins of replication.
What are enzymes that have a proofreading role in DNA replication?
DNA polymerases
How does mutations occur during DNA replication and transcription?
RNA polymerase doesn't have a proofreading function.
What would be a consequence if DNA proofreading and correction was perfect?
if it is perfect then everything is fine, the replication and the following process will go on..
What is the function of DNA helicare in DNA replication?
DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.
What function does DNA polymerase have to enable it to detect errors and correct them?
proofreading
Compare the polymerase chain reaction and DNA replication?
PCR need thermostable enzyme like taq DNA polymearse, while in replication using highly proofreading enzyme DNA polymerase. taq enzyme work in very high temprature while in replication our body temprature
What does the word replicate mean involving DNA?
DNA replication, the basis for biological inheritance, is a fundamental process occurring in all living organisms to copy their DNA. This process is "replication" in that each strand of the original double-stranded DNA molecule serves as template for the reproduction of the complementary strand. Hence, following DNA replication, two identical DNA molecules have been produced from a single double-stranded DNA molecule. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication. by: Denfol Gevero
What is the function of the DNA in a chloroplast?
They code for proteins. DNA allows self replication of chloroplasts
DNA is copied during a process called?
Replication.
What enzyme attaches and adds the matching nucleotides?
DNA Polymerase III adds nucleotides during DNA replication. DNA Polymerase I also adds nucleotides (to a lesser extent). DNA Pol I is responsible for replacing the primers with dNTPs, these sections are then joined to the rest by DNA Ligase.
During replication what is the function of the enzyme DNA polymerase?
DNA polymerase are enzymes that form bonds between nucleotides during replication.
What does DNA polymerase 1 do?
DNA polymerase 1 is involved in replication when proofreading and repairing of the DNA sequence as well as removal of RNA primers placed by primase so that DNA polymerase 3 can successfully attach the complementary strand of DNA
