What used to copy DNA?
Recombinant DNA technology
Is Gel Electrophoresis used to make many copies of DNA?
no, it is used to separate different sized pieces of DNA using a gel and an electric current. Polymerase Chain Reaction (PCR) is the multiplication of DNA with the use of a PCR machine, enzymes and primers. The PCR machine allows the multiplication of DNA through temperature changes, activating each step of the reaction and copying DNA millions of times.
How does the polymerase chain reaction make DNA more reliable?
The polymerase chain reaction (PCR) amplifies specific regions of DNA, making them easier to detect and study. By creating millions of copies of a target DNA sequence, PCR increases the reliability of detecting mutations or variations in the DNA. This increased specificity and abundance of DNA copies make PCR a valuable tool in various genetic analyses.
How many copies of DNA does each cell have in the human body?
Each cell in the human body typically contains two copies of DNA.
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 was it difficult to used DNA as evidence in a crime before PCR was invented?
you need many copies of DNA for DNA fingerprinting

Is PCR the technique used to make multiple copies of even a fragment of DNA?
that is a true statement

What is amplification when referring to DNA synthesis?
Amplification is the production of many copies of a particular DNA segment. The copying repeats - so that copies of the copies are made. This results in many, many copies in only a few cycles. PCR (Polymerase Chain Reaction) is the most common method of amplifying DNA.
How many copies of DNA are made?
2
How many copies of a DNA result from two replication of a single DNA?
Four.
Process by which DNA copies itself?
Replication! 1) DNA splits 2) DNA copies 3) left with 2 copies of DNA! :)
How many copies of DNA does each cell have in the human body?
Each cell in the human body typically contains two copies of DNA.
How many copies of a DNA molecules result from replications of a single DNA molecule?
Four.
