With use of enzymes, reagents and a thermocycler (apparatus which raises and lowers temperature as programmed), DNA sequences are multiplied rapidly.

What is a method of making any copies of DNA?
Polymerase chain reaction (PCR) is the method of making copies of DNA.
Why was it difficult to use DNA as evidence in a crime before PCR was invented?
you need many copies of DNA for DNA fingerprinting
How does the polymerase chain reaction make DNA more reliable?
It allows scientists to quickly make many 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.
Gene cloning is an efficient way to produce many copies of a specific DNA sequence?
True
What is a method of making any copies of DNA?
Polymerase chain reaction (PCR) is the method of making copies of DNA.
What is method of making many copies of DNA?
Polymerase chain reaction
What is a method of makeing many copies of DNA?
Polymerase chain reaction
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! :)
Which is a method of making copied of DNA?
polymerase chain reaction
Is it true that Messenger RNA carries copies of the instructions for making proteins from DNA to other parts of the cell?
Yes. Specifically mRNA carries copies of the instructions for making proteins from DNA to ribosomes, either free in the cytoplasm or attached to rough ER.
How many copies of a DNA molecules result from replications of a single DNA molecule?
Four.
How many copies of a DNA molecule result from two replications of a single DNA?
Four.
