there are many different vectores as:
1-plasmid system
2-bacteria phage lamda
3-cosmids
4-bacterio artificial system
5-puc system
the other cloning vectors are
m13 which is the oldest one.
and after the above all are:-
BAC(bacterial artificial chromosome)
YAC(yeat artificial chromosome)
TAC(transformation-competent artificial chromosome)
Plasmid,phagemid,virus based vectors,BAC,cosmid and eukaryotic vectors like YAC etc are common vector in r-dna technology....
In the lab I work in we use E. coli and Salmonella e.
1. A vector such as plasmid is needed along with a host cell. Restriction enzymes and DNA ligase are enzymes that are used to introduce foreign DNA into a vector.
"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".
Two forms of technology used today are computers and cell phones. The average household family of four might have 3 cell phones and 2 or more computer devices, depending on the age of the children.
Thousands, if not millions. There are so many that it would be a major task to catalog them all. They could be categorized by technology used or by function.
TECHNOLOGY actually means 'knowing how to do something'. Anything you know how to do is a technology.In modern times there are a number of different types of technologies emerging; these are centred around ways we live and how we make our lives more comfortable. For example:1. Assistive technology is technology used by individuals with disabilities in order to perform functions that might otherwise be difficult or impossible2. Medical technology refers to the diagnostic or therapeutic application of science and technology to improve the management of health conditions3. Information technology refers to both the hardware and software that are used to store information4. Communications technology5. Transport technology6. Defence technology
Recombinant DNA technology PCR
it is a ds DNA use in recombinant DNA technology to insert our interested gene and multiply it.Ex;plasmid,cosmid
Vector are plasmid DNA, act as a molecular vehicles to carry genes or DNA of interest. In rDNA technology vectors used to clone the gene by ligation. This chimeric DNA or plasmid can be propagated in E.coli as the vector carries its own origin of replication. Expression plasmid vectors can be used to produce proteins from the gene of interest.
Recombinant DNA technology
Linkers are synthetic double strsnded oligonucleotide which contain within them one or more Restriction sites that are used to ligate the gene of interest to the vector DNA.
How can recombinant DNA technology be used to combat HIV infections?
A pUC vector a circular, double stranded DNA molecule normally used for recombinant protein expression. It is not a math vector.

B. They divide quickly -apex
pcDNA is DNA vector used to clone recombinant DNA sequences for the expression of proteins of interest in mammalian cells.
