In gene-cloning projects, plasmids function to allow replication of the DNA that's being cloned. Gene cloning describes the process of copying fragments of DNA which can then be used for many different purposes, such as creating genetic modified crops. There may be two types; in vitro which involves using polymerase chain reaction to create copies of DNA fragments or the in vivo which involves use of restriction enzymes and ligases using vectors and cloning the fragments into host cells.
The potassium 40 to calcium or argon 40 half-life is 1.25 billion years so if this half-life is displayed then the age of 1.25 billion years would be valid. Half life is the time it takes for an isotope to decay into half its' amount and which in the process is losing its radioactivity.
