Gel electrophoresis can be used to separate various pieces of DNA by their lengths. When the location of target strands of DNA need to be located, specific restriction enzymes function to sever the particular DNA strand, and then take the desired, different strands of DNA (severed by the same restriction enzyme) and adds it to the original specimen of DNA. I know this works on plasmids (circular pieces of DNA found in bacteria). Very, very interesting stuff.

PCR
True or false cell increases in size it usually makes extra copies of its DNA?
A cell does not make "extra copies" of DNA. Through a persons life, DNA can only be copied so many times. The only time DNA does "copy itself" would be if a new cell is needed. For example, your skin cells die all the time and are shedded off from your skins surface. Your skin then is going to get to the point where more cells are going to be made. The DNA replicating process is what starts the process of cell mitosis (making more cells). All the DNA in your body is used, so a cell does not make extra copies of DNA. If the DNA gets destroyed, that cell dies and is replaced by another.
Why rna primer is used instead of dna primer?
There are basically two types of enzymes that can bind to DNA and copy it. The DNA polymerase and the RNA polymerase. The RNA polymerase, which copies DNA into RNA, will only bind to single stranded DNA, in other words areas of the DNA where the nitrogen bases holding the two strands of nucleotide units together have been separated. On the other hand the DNA polymerase that copies DNA into DNA will only bind to DNA that is double stranded. So in lies the dilemma. To make a copy of the DNA the DNA polymerase is use, but it will not bind to single stranded DNA so there is no way to make a DNA primer using aDNA polymerase, but the RNA polymerase will bind to single stranded DNA and there for can be used to make a small RNA primer on the open strands of DNA. Now the DNA polymerase has place that is double stranded and can attach and start copying the DNA.
Is PCR the technique used to make multiple copies of even a fragment of DNA?
that is a true statement
Who does DNA make copies of itself?
meosis
What is used to make many copies of DNA?
Recombinant DNA technology PCR
Process by which DNA copies itself?
Replication! 1) DNA splits 2) DNA copies 3) left with 2 copies of DNA! :)
Why was polymerase chain reaction developed?
makes more copies of a sample of DNA. apex
How does the polymerase chain reaction make DNA more reliable?
It allows scientists to quickly make many copies of DNA
Why was it difficult to used DNA as evidence in a crime before PCR was invented?
you need many copies of DNA for DNA fingerprinting
Which is used to create copies of genetic material for DNA fingerprints?
PCR
How does the polymerase chain reaction make DNA fingerprinting more reliable?
It allows scientists to quickly make many copies of DNA.
What is quantitative pcr technology used for?
Quantitative PCR Technology is used in biochemistry, in particular molecular biology. The PCR stands for polymerase chain reaction and is used to "amplify" pieces of DNA to make millions of copies of a particular DNA strand.
The two exact copies of DNA that make up a chromosome are called?
Chromatids.
Why does DNA make copies?
as cell divides the DNA also hav to divide to b transfferd in to newly formed cell so for that DNA divides
