Answer

Gene cloning is the process of producing multiple identical copies of a specific gene. This is done using recombinant DNA technology, where the desired gene is inserted into a bacterial plasmid. As th…

Answer

A gene bank is a collection of bacterial or bacteriophage clones, each carrying a specific foreign DNA segment (gene). These clones are preserved at very low temperatures for future use. For example, …

Answer

Plasmids are small, circular DNA molecules found in bacteria that are separate from the bacterial chromosome. They are used as vectors in gene cloning because they can easily be removed, cut with rest…

Answer

Restriction endonucleases are enzymes that cut DNA at specific nucleotide sequences. They are used in recombinant DNA technology to cut both the desired gene from the source organism and the plasmid v…

Answer

Recombinant DNA technology is a technique used to combine DNA from two different sources. It involves cutting a specific gene from one organism using restriction enzymes, inserting it into a plasmid v…

Answer

DNA splicing is the process of joining two pieces of DNA from different sources. In recombinant DNA technology, after cutting DNA with restriction enzymes, the desired gene is joined with a plasmid ve…

Answer

1. Isolation: The desired gene is cut from the source DNA using restriction enzymes. 2. Vector Preparation: A plasmid is cut with the same enzyme. 3. Recombination: The foreign gene is inserted into t…

Answer

A transgenic organism is an organism that contains a foreign gene from another species in its genome. This is achieved through genetic engineering. For example, a transgenic goat may carry a human gen…
