Why is the largest DNA fragment band found closest to the well in which it was placed?
why is the largest DNA fragment band found closest to the well in with it was placed
What type of enzyme is used to fragment dna?
restriction enzymes are used to cut DNA.
What is the role of DNA ligase in the enlogation of the lagging strand during DNA replication?
it is a linking enzyme essential for DNA replication; catalyzes the covalent bonding of the 3' end of one DNA fragment to the 5' end of another DNA fragment.
What general shape does this fragment of DNA resemble?
The DNA molecules resembles a twisted step ladder
What is the toxin that T cell secrete to fragment DNA?
Lymphotoxins
Why does the DNA fragment size change as you move from the cathode to the anode?
The DNA fragment size decreases as it moves from the cathode to the anode. This is due to the negative charge of the DNA moving against the positive charge of the cathode.

A dna fragment with a sticky end that reads -attcg will bind with another dna fragment with a sticky end that reads?
ATTCG signify adenine (A), thymine (T), cytosine (C) and guanine (G). The bonding pairs are AT, GC when DNA replicates. Therefore the fragment ATTCG will bind to TAAGC.
What is the toxin that T cell secrete to fragment DNA?
Lymphotoxins
Which fragment of DNA is the longest or biggest?
The fragment of the DNA that is the longest is the one that is the slowest to get to the bottom of the gel in the body. This is because longer DNA are simply the largest base pairs that are digested in the restriction enzymes which make them slower then the shorter ones.
Is genetic egineering the insertion of a small fragment of frog DNA into the DNA of another species?
Genetic engineering
What is a vector used for in a genetic engineering experiment?
"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".
What are phage vectors?
"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".Commonly used vectors include plasmid, Lambda phage, cosmid and yeast artificial chromosome (YAC).
Why might a laboratory be using dideoxy nucleotides?
To sequence a DNA fragment
