I hope this will help you: http://www.sfusd.edu/programs/sf_base/protocols/lab_104_lambda.pdf Fun Fact: DNA stands for Deoxyribonucleic acid (But, you probably already knew that).
The enzyme that cuts the bonds of DNA at the origin of replication is called DNA helicase. DNA helicase plays a key role in unwinding the double helix structure of DNA so that it can be replicated.
A restriction enzyme is a degradative enzyme that recognizes specific nucleotide sequences and cuts up DNA. These enzymes are often used in biotechnology to cut DNA at specific sites for genetic engineering purposes.
when restriction enzyme is use on DNA basically it just first losen up the DNA, usally DNA is coiled, and so the restriction enzyme jsut breka the DNA and leave a sticky end, so that it can be put back together, the cell have to be able to do that because in nature, that's the way for cell to stop protein production and the cell still need that gene
A restriction enzyme is used to cut DNA (either double or single stranded), cuts can either be "sticky" ( in which cut pieces overlap one another), or "blunt" (in which cut pieces do not overlap). A common rectriction enzyme is EcoR1.
Restriction enzymes can be identified based on their specific recognition sequence, which is a short, palindromic DNA sequence that the enzyme binds to and cleaves. Each restriction enzyme recognizes a specific sequence and cuts the DNA at a specific location within or near that sequence. Additionally, the supplier or manufacturer of the enzyme will provide information on its specific recognition sequence and optimal conditions for use.
The enzyme that cuts DNA is called a restriction enzyme, while the enzyme that seals DNA is called DNA ligase. Restriction enzymes cut DNA at specific sequences, creating breaks in the DNA strands, while DNA ligase seals these breaks by catalyzing the formation of phosphodiester bonds between the DNA fragments.
The restriction enzyme EcoRI cuts DNA at a specific sequence of bases, which is GAATTC.
The enzyme that cuts the bonds of DNA at the origin of replication is called DNA helicase. DNA helicase plays a key role in unwinding the double helix structure of DNA so that it can be replicated.
The restriction enzyme EcoR1 specifically cuts the DNA sequence at the recognition site GAATTC.

A restriction enzyme is a protein that cuts DNA at specific sequences, allowing scientists to manipulate and study DNA by cutting it into smaller fragments.

Such an enzyme is called a restriction endonuclease
A restriction enzyme is a protein that cuts DNA at specific sequences, allowing scientists to manipulate and study DNA molecules in molecular biology experiments.
The enzyme that cuts out the RNA primer on the replicated DNA molecule and replaces it with the appropriate DNA nucleotides is DNA polymerase I in prokaryotes and DNA polymerase delta in eukaryotes. This process, known as primer removal or primer excision, is essential for completing DNA replication accurately.
