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.

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 true of the DNA fragment band closest to the positive end of the gel?
they are the smallest.
Is DNA considered an organelle?
gene is not an organelle but is a fragment of DNA with a specific expression or product in cell funtion
How is DNA fingerprint a specific type of restriction map?
They both show the size of DNA fragment due to the number of repeats. They represent the uniqueness of a person's DNA.
How can PCR help to detect very low amounts of DNA?
it do so by amplification of the small DNA fragment ( with the help of promoters and enzymes)
Why is the largest DNA fragment band found closest to the well in which it was placed?
The largest DNA fragments travel more slowly through the agarose gel due to their size, so they don't move as far from the well as smaller fragments during gel electrophoresis. This results in the largest fragments being closest to the well after electrophoresis is completed.
What is the moving fragment of DNA?
Genetic Engineering..
Why does the DNA fragment size change as you move from the cathode to the anode?
In gel electrophoresis, DNA fragments move towards the anode (positive electrode) because DNA is negatively charged. Smaller fragments move faster through the gel matrix, so they appear closer to the anode while larger fragments move slower and appear closer to the cathode. This results in separation of DNA fragments based on size.
What type of enzyme is used to fragment dna?
Restriction enzymes are used to fragment DNA by cutting it at specific recognition sites. These enzymes are naturally found in bacteria as a defense mechanism against foreign DNA, and are commonly used in molecular biology techniques like restriction enzyme digestion.
What is the role of DNA ligase in the enlogation of the lagging strand during DNA replication?
DNA ligase plays a crucial role in the elongation of the lagging strand during DNA replication by sealing the nicks between the Okazaki fragments. It catalyzes the formation of phosphodiester bonds between adjacent nucleotides, joining the fragments together to form a continuous strand. This ensures the completion of the synthesis of the lagging strand and the formation of a fully functional double-stranded DNA molecule.
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 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
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?
Phage vectors are bacteriophages modified to carry foreign DNA and deliver it into a bacterial host cell. These vectors can be used for genetic engineering purposes and often serve as tools for cloning and manipulating genes. Once the phage infects the host cell, the foreign DNA is integrated into the host's genome and can be expressed.
Why might a laboratory be using dideoxy nucleotides?
To sequence a DNA fragment
