Polymerase 1 without 5' to 3' activity is called exonuclease. It is responsible for removing RNA primers during DNA replication.
Cellular activity refers to the various processes that take place within a cell, such as metabolism, growth, and replication. These activities are essential for the cell to function and carry out its specific role in the organism.
The physical component of Active directory contain all the physical subnet present in your network like domain contollers and replication between domain contollers.The logical structure of active directory include forest, domains, tree, OUs and global catalogs.Domain : a group of computer and other resources that are part of a windows server2003 network and share a common directory database.Global catalog : Global catalog used to catch information about all object in a forest , the global catalog enables users and applications to find object in an active directory domain tree if the user or application knows one or more attributes of the target object.Tree : Tree as is collection of Active directory Domain, that means the trust relationship can be used by all other domain in the forest as a means to access the domain.Organization Unit - Organization Unit is a Active directory container into which object can be grouped for per mission management.Forest : Active directory forest as due to represents the external boundary of the directory service.These are two types of active directory forest :-I) Single Forest2) Multiple forest
3'5' exonuclease activity refers to an enzyme's ability to degrade DNA or RNA molecules by removing nucleotides one at a time from the 3' to the 5' end of the strand. This type of exonuclease activity is important in proofreading and repairing DNA replication errors.
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.
1. In eukaryotic cells replication forks make several start sites along the DNA strand which forms replication "bubbles" which get larger the more DNA is copied, and stop when DNA replication is complete. In prokaryotic cell's DNA is formed in a loop, two replication forks start along one part of the loop (origin replication) and the replication forks copy DNA in opposite directions until they meet at the other side of the loop, making an exact copy of DNA.
DNA polymerases, such as DNA polymerase III in prokaryotes and DNA polymerase delta in eukaryotes, have proofreading activities during DNA replication. These enzymes possess exonuclease activity, allowing them to detect and correct errors in newly synthesized DNA strands by removing misincorporated nucleotides. This proofreading function helps maintain the fidelity of DNA replication.

You might want to be more specific, as 'cell activity' is kind of (well, extremely) general. In short and shotgun answer: many, many different kinds. Metabolism, protein synthesis, replication to name a few of the most important processes.
Yes, DNA polymerase has proofreading activity, which allows it to correct mistakes during DNA replication. This helps maintain the accuracy of the DNA sequence.
Efficiency in proofreading activity of DNA polymerase is achieved through its ability to recognize and remove incorrectly paired nucleotides during DNA synthesis. This process involves the exonuclease activity of DNA polymerase, which allows it to backtrack, excise the mismatched base, and replace it with the correct one. This proofreading mechanism helps ensure high fidelity in DNA replication.
