What is the difference between endonuclease and exonuclease activity in DNA degradation processes?
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.
What is the difference between a restriction enzyme and an endonuclease?
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.
Does RNA polymerase have exonuclease activity during transcription?
No, RNA polymerase does not have exonuclease activity during transcription.
What could account for low endonuclease activity?
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.
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 endonuclease and exonuclease activity in DNA degradation processes?
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.
What is the enzyme that opens up DNA?
restriction endonuclease and exonuclease
What is the difference between Restriction endonucleases and exonucleases?
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).
What is the difference between a restriction enzyme and an endonuclease?
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.
What is the difference between DNA polymerase III and DNA polymerase I?
pol 1 - exonuclease activity pol 2 - dna repair pol 3 - primary replication enzyme
Does RNA polymerase have exonuclease activity during transcription?
No, RNA polymerase does not have exonuclease activity during transcription.
What is the molecule used to cut the gene from the DNA in an organism?
Restriction endonuclease
Do eukaryotes have restriction endonuclease?
no
What is 3'5' exonuclease activity?
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.
What is a RNA primer removed by?
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.
What is is a linker?
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.
What molecule is uses to cut out a section of DNA?
restriction endonuclease
