3'-5' is a characteristic feature of DNA-polymerase I. This activity is meant to repair any misparing mistakes that the enzyme may commit during the synthesis, in which the enzyme would reverse its direction by ONE NUCLEOTIDE and excised the mistakenly added nucleotide, the enzyme acts at the phosphodiester bond at the 5 prime.
Whereas the 5'-3' exonuclease activity is an also repair strategy exercised by the DNA polymerase I. However, in this case the polymerase would move in the forwards direction and excise the miss-matched nucleotides at any position regardless with one nucleotide far or so many. This mechanism of repair is well documented in case UV-mutation.

Vivi3' to 5' exonuclease activity refers to the ability of an enzyme to degrade DNA from the 3' end towards the 5' end, while 5' to 3' exonuclease activity degrades DNA in the opposite direction, from the 5' end towards the 3' end. These activities are important in processes like DNA repair, proofreading during DNA replication, and removal of RNA primers during DNA synthesis.

Polymerase 1 without 5' to 3' activity is called?
Polymerase 1 without 5' to 3' activity is called exonuclease. It is responsible for removing RNA primers during DNA replication.
What type of biological molecule is an exonuclease?
An exonuclease is an enzyme that hydrolyzes nucleotides from the end of a nucleic acid chain. It is a type of protein, which is a biological macromolecule responsible for catalyzing biochemical reactions in living organisms.
What is the difference between IBA and IAA?
IBA (Indole-3-butyric acid) and IAA (Indole-3-acetic acid) are both plant hormones known as auxins used in plant propagation. The main difference between the two is their chemical structure and concentrations needed for effectiveness. IBA is typically more stable and effective for root initiation, while IAA is a naturally occurring auxin found in plants.
How are bonds between A-T and G-C different?
Bonds between A-T are hydrogen bonds, which form a two hydrogen bond pair, whereas bonds between G-C are also hydrogen bonds, but they form a three hydrogen bond pair. This difference in bond strength contributes to the stability of the DNA double helix structure.
What the difference in a 3 toe and a 4 toe dragon?
A 3-toed dragon has three toes on each foot, while a 4-toed dragon has four toes on each foot. This difference in toe count is a characteristic used to differentiate between certain species of dragons in mythology or fictional works.
