Most DNA Polymerases and RNA polymerases have what is known as "proof-reading activity". This is the ability of the enzymes to check what bases they have added during DNA replication (in the case of DNA Polymerase) or transcription (in the case of RNA Polymerase), and if an error is found, splice it out and replace it with the correct base. The mode of action depends on the enzyme in question - some use endonucleases, and some use exonucleases; some work 5'-3' while others work 3'-5'. Also note that I said MOST polymerases have proof-reading capabilities...there are a few which do not (or don't proof-read very well).
What else can I help you with?
Role of RNase in DNA purification?
RNase is important in DNA purification as it helps to degrade RNA contaminants that may be present in the sample. By degrading RNA, RNase ensures that the purified DNA sample is free of RNA, which could interfere with downstream applications such as PCR or sequencing. Purifying DNA with RNase treatment helps to ensure the accuracy and reliability of the subsequent analysis.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
What base does RNA have that DNA does not have?
RNA has the base uracil that DNA does not have.
What are the 30 differences between DNA and RNA?
Comparing DNA and RNA, some key differences include: DNA is double-stranded, while RNA is single-stranded; DNA contains deoxyribose sugar, RNA contains ribose sugar; DNA has thymine base, RNA has uracil base; DNA is found in the nucleus, RNA is found in the cytoplasm; DNA is stable, RNA is less stable; DNA is the genetic material, RNA is involved in protein synthesis. These are just a few of the many distinctions between DNA and RNA.
Why each the following identify if it relates to DNA RNA both DNA and RNA or neither DNA nor RNA.?
For each the following, identify if it relates to DNA, RNA, both DNA and RNA, or neither DNA nor RNA.1. Is a polymer of nucleotides2. Contains adenine3. Is a special type of protein4. Contains thymine5. Contains uracil6. Has sugar-phosphate backbone7. Contains pentose sugar8. Contains Ribose9. Helix10. Double-strand molecule

What is a rudder in polymerase?
In the context of polymerase, particularly RNA polymerase, a "rudder" refers to a structural element that helps guide the DNA-RNA hybrid during transcription. It plays a crucial role in maintaining the stability of the RNA-DNA complex and facilitating the proper positioning of the RNA strand as it is synthesized. By directing the RNA strand, the rudder contributes to the efficiency and accuracy of transcription.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
What is the name of the nucleotides have no DNA and no RNA?
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
What is the substance in RNA but not DNA?
An uracil base is in RNA but not in DNA
What base does RNA have that DNA does not have?
RNA has the base uracil that DNA does not have.
Are DNA and RNA carbohydrates?
Yes, DNA and RNA have different sugar . DNA contains deoxyribose sugar whereas RNA consists of ribose sugar, which are completely different from each other.

Which neuclitides found in RNA not in DNA?
Uracil is a nucleotide found in RNA but not in DNA. In RNA, uracil replaces thymine, which is found in DNA.
Which molecules is typically found in DNA but not RNA?
Thymine is found in DNA but not in RNA. Uracil replaces thymine in RNA. In other words: DNA has thymine. RNA has uracil.

Is DNA shorter then RNA?
No... DNA is much longer than RNA.
