Enzymes that are able to cut DNA are called rstriction enzymes. These enxymes are site specific. This means the cuts they produce are not ramdom events. They cut the DNA strand only when a particular sequence is encountered. This sequence on the DNA is called the restriction site. Restriction sites vary in length from 6 - 8 or more nucleotides. This evidence indiates restriction enzymes cut DNA at a unique site
The restriction enzyme EcoRI cuts DNA at a specific sequence of bases, which is GAATTC.
Such an enzyme is called a restriction endonuclease
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 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.

When EcoR1 cuts this DNA, it cuts it at three places into four different segments. EcoR1 is only one of many different restriction enzymes. Each different enzyme cuts DNA at a different site. By using different enzymes, a scientist can cut DNA into many smaller pieces that can be run out on a gel during electrophoresis. Remember that in gel electrophoresis, DNA fragments separate by size. Because these segments have different sizes, they will separate onto a gel at different rates. If different people's DNA is cut by restriction enzymes and then run out on a gel, each person's DNA will leave a different pattern.

If a restriction enzyme cuts a plasmid more than once, it may create multiple fragments that can't be easily re-ligated back together. This can result in a mix of different plasmid forms, making it challenging to obtain a pure, single-cut product for downstream cloning experiments.
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.
