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 enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
A major difference in RNA as compared to DNA is?
RNA can move and DNA cant. DNA has a double helix strand and RNA is a single strand.
What two biomolecules can carry the genetic information for a virus?
DNA and RNA. Viruses that use RNA often have to have enzymes that convert the RNA to DNA.
What are the main characteristics of DNA and rna?
DNA is double stranded while RNA is single stranded. DNA uses thymine but RNA uses uracil.
What enzyme matches RNA nucleotides to complementary DNA nucleotides?
RNA polymerase
What are two types of nucleic acid found the cell?
Two types of nucleic acids found in cells are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA stores genetic information and is typically found in the cell nucleus, while RNA plays a role in protein synthesis and can be found in the nucleus and cytoplasm.
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 enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
A major difference in RNA as compared to DNA is?
RNA can move and DNA cant. DNA has a double helix strand and RNA is a single strand.
What is the substance in RNA but not DNA?
An uracil base is in RNA but not in DNA
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.
What two biomolecules can carry the genetic information for a virus?
DNA and RNA. Viruses that use RNA often have to have enzymes that convert the RNA to 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.
Why is it important for RNA to be smaller then DNA?
Because RNA is the replication of DNA.
Is DNA shorter then RNA?
No... DNA is much longer than RNA.
What nitrogen base in RNA is not part of DNA?
uracil is in rna not in DNA
What bases found in DNA but not in RNA?
Uracil is found in RNA but not in DNA.
