an exonuclease cleaves nucleotides from the end of a polynucleotide chain whereas an endonuclease cleaves nucleotides from within a polynucleotide chain
Endonuclease activity involves cutting DNA internally, while exonuclease activity involves cutting DNA from the ends. In DNA degradation processes, endonucleases break DNA strands at specific points, while exonucleases remove nucleotides from the ends of DNA strands.
A restriction enzyme is a type of endonuclease. Endonucleases are enzymes that cut DNA at specific sequences, while restriction enzymes specifically cut DNA at recognition sites called restriction sites.
No, RNA polymerase does not have exonuclease activity during transcription.
Low endonuclease activity could be due to improper folding or denaturation of the enzyme, suboptimal pH or temperature conditions for activity, or lack of cofactors required for enzymatic function. Additionally, mutations in the gene encoding the endonuclease enzyme could also lead to reduced activity.
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.
Endonuclease activity involves cutting DNA internally, while exonuclease activity involves cutting DNA from the ends. In DNA degradation processes, endonucleases break DNA strands at specific points, while exonucleases remove nucleotides from the ends of DNA strands.
restriction endonuclease and exonuclease
Exonuclease enzymes cleave nucleotides from the ends of DNA molecules. Endonuclease enzymes cleave a phosphodiester bond somewhere within the DNA molecule (not at the ends).
A restriction enzyme is a type of endonuclease. Endonucleases are enzymes that cut DNA at specific sequences, while restriction enzymes specifically cut DNA at recognition sites called restriction sites.

no
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.
A RNA primer in DNA replication is removed by an enzyme called DNA polymerase I in prokaryotes and DNA polymerase δ in eukaryotes. These enzymes have exonuclease activity that can remove RNA primers and replace them with DNA nucleotides.
The DNA found between nucleosomes on chromatin; since it is not complexed to proteins as strongly as other forms of dna, it is accessible to exonuclease hydrolysis.
