cutting of DNA into fragments simply means application of suitable restriction enzyme to it.now a days two types of restriction enzymes are available,1)exonucleases,which cut at end portion of DNA and 2)endonucleases ,which cut at specific inner site.
EcoR1 cuts double-stranded DNA at specific recognition sites generating two fragments, so to generate 4 fragments, EcoR1 would need to cut the DNA twice.
BamHI is a restriction enzyme that recognizes the specific DNA sequence "GGATCC" and cuts between the G and the A. The number of DNA fragments produced by BamHI cutting a DNA molecule depends on the number of BamHI recognition sites present in that molecule. Each recognition site will result in one additional fragment; thus, if there are n cut sites, the DNA will be divided into n+1 fragments.
Restriction enzymes that recognize and cut eight-base pair DNA sequences typically produce the smallest DNA fragments. Examples include restriction enzymes like MspA1I and TaqI. These enzymes can be useful for generating very small DNA fragments for various molecular biology applications.
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 lagging strand of DNA is replicated in Okazaki fragments. These short, discontinuous fragments are synthesized as the DNA replication process moves away from the replication fork. They are eventually joined together by DNA ligase to form a continuous strand.
It is important because the fragments will bond to other fragments with complementary single-stranded ends.

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.
Plasmids are circular pieces of DNA, so the number of fragments equals the number of cuts from the restriction enzymes. You can easily see this if you start with one restriction enzyme that cuts the plasmid in only one place. Cutting the circle in one place yields you only one fragment. If the restriction cuts in two places, you end up with two fragments; with three places, three fragments, etc. With linear chromosomes, the situation is different. Cutting a linear chromosome in one place yields two fragments, cutting in two places yields three fragments, etc. So the number of fragments is always one more than the number of cuts. A restriction map of a plasmid will show all of the cuts the restriction enzymes made. Each cut is labeled with the enzyme that made it. One can count the spaces between cuts to determine the number of fragments that are produced. Restriction maps usually (but not always) also show the size of each fragment.
You get DNA fragments by entering Bakugan codes.
The process of adding fragments of DNA to other DNA is called DNA ligation. This involves joining together two DNA fragments using an enzyme called DNA ligase, which helps to form a covalent bond between the DNA fragments.
Three.To see why, cut a piece of string in two places! Of course, strictly you would not be able to see only three fragments. You would amplify the DNA before carrying out electrophoresis. That way, you would get perhaps 200 million copies of each fragment, and they would show up. Also, you would only be able to distinguish the fragments if they were different lengths. Electrophoresis separates pieces of DNA by length.
In gel electrophoresis, a DNA ladder serves as a reference for determining the sizes of DNA fragments being analyzed. It contains DNA fragments of known sizes, which help in estimating the sizes of unknown DNA fragments by comparison. This aids in accurately identifying and analyzing the DNA fragments present in the sample.
When You collect 20 DNA fragments you get a free bakugan
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.
