How does the rolling circle replication work?
Rolling circle replication is a mechanism used by some viruses and plasmids to replicate their circular DNA molecules. It involves the synthesis of a single DNA strand, which serves as a template for the production of multiple copies. The rolling circle mechanism starts with the nicking of a circular DNA molecule, followed by the synthesis of a new strand that displaces the original strand, forming a long single-stranded DNA loop. This loop can then be cleaved into unit-length copies to generate multiple identical circular DNA molecules.
Gene cloning is an efficient way to produce many copies of a specific DNA sequence?
Yes, gene cloning involves inserting a specific DNA sequence into a vector, such as a plasmid, to produce multiple copies of that DNA sequence. This can be useful for producing large amounts of a particular gene for further research or application.
What is the purpose of the polymerase chain reaction (PCR)?
Polymerase Chain Reaction (PCR) testing is a technique to amplify a single or few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. This allows for easier identification of particular DNA segments and can be used to assist in the diagnosis of certain diseases.
What is a method of making any copies of DNA?
One method of making copies of DNA is through a process called polymerase chain reaction (PCR). In PCR, a DNA template is mixed with primers, nucleotides, and DNA polymerase, and subjected to cycles of heating and cooling to amplify the target DNA region. This results in millions of copies of the DNA target.
What is the function of PCR in molecular biology?
The function of PCR in molecular biology is to amplify a specific segment of DNA, making multiple copies of it for further analysis and study.
What is the process that allow millions of copies of DNA to be produced?
DNA fingerprinting
Is PCR the technique used to make multiple copies of even a fragment of DNA?
that is a true statement
Process by which DNA copies itself?
Replication! 1) DNA splits 2) DNA copies 3) left with 2 copies of DNA! :)
What are concatamers and what type of DNA replication is responsible for producing concatamers?
Concatamers are long DNA molecules that result from multiple copies of a DNA sequence being connected end-to-end. Concatamers are typically produced during rolling circle replication, a type of DNA replication common in viruses and certain bacterial plasmids.
How does a virus multiplied?
A virus injects its DNA into the host cell making it produce multiple copies of that DNA and multiple copies of the protein capsule of that virus. After a while, the host cell becomes full of many copies of that virus, then the host cell explodes releasing all the new viruses. If the host cell is a bacterium and the the virus is a bacterophage, this phenomenon is done in two ways either by the lytic cycle in which virus DNA survives and the bacterial cell is destroyed,or the lysogenic cycle in which virus DNA is incorporated in the host cell DNA.
What makes copies of viral DNA?
During the process of viral replication, the virus uses host cells to produce copies of its viral DNA. This process typically involves the virus injecting its genetic material into the host cell's nucleus, where it hijacks the cell's machinery to replicate its DNA. This results in the production of multiple copies of the viral DNA, which can then be packaged into new viral particles.

Why is important that exact copies of DNA are produced during replication?
because if not.. it will cause DNA mutation... your features may change or worst.. it may cause cancer... because in theory.. cancer is caused by DNA mutations...
