TA Cloning is one of the most popular methods of cloning the amplified PCR product using Taq and other polymerases. These polymerases lack 5'-3' proofreading activity and are capable of adding adenosine triphosphate residue to the 3' ends of the double stranded PCR product. Such PCR amplified product can be cloned in a linearized vector with complementary 3' T overhangs.
TA cloning is brought about by the terminal transferase activity of certain type of DNA polymerase such as the Taq polymerase. This enzyme adds a single, 3'-A overhang to each end of the PCR product. As a result, the PCR product can be directly cloned into a linearized cloning vector that have single base 3'-T overhangs on each end. Such vectors are called T- vectors. The PCR product with A overhang, is mixed with this vector in high proportion. The complementary overhangs of a "T" vector and the PCR product hybridize. The result is a recombinant DNA, the recombination being brought about by DNA ligase.

Is a cloning vector a plasmid?
plasmid is the type of the cloning vector. other cloning vectors includes cosmids, bacteriophage, phagemids, artifiical chromosomes. clonong vectors are the carriers of certain traits to be inserted in non coding regions of the DNA.
What is the insert capacity of a cosmid vector in DNA cloning?
The insert capacity of a cosmid vector is about 35-45 kb.
How can you know donored-vector is cloning vector or expression vector?
Expression vectors contain translation start and termination codons. Moreover, it contains promoter region
The host organism into which a cloning vector is placed is called?
Competent cells if i not mistaken
What is an agent that is used to carry a DNA fragment isolated from one cell into another cell?
cloning vector
What is the cloning capacity of pBR322 vector?

Why is cloning an example of cloning?
Gene Cloning is used to clone a gene of interest in a vector called plasmid. The chimeric DNA or rDNA formed by cloning is stable and can be used to propagate and sequence the DNA. producing vector containing inulin gene is an example.
What is the insert capacity of a cosmid vector in DNA cloning?
The insert capacity of a cosmid vector is about 35-45 kb.
What a good cloning vector should have?
The good cloning vector should have small size, high copy number, own origin of replication, restriction sites for many restriction enzymes and selectable markers.
How can you know donored-vector is cloning vector or expression vector?
Expression vectors contain translation start and termination codons. Moreover, it contains promoter region
The host organism into which a cloning vector is placed is called?
Competent cells if i not mistaken
Does a cloning vector contain promoter region?
No, not really since it is just for cloning. But their should be enough promoter/sequence to provide antibiotic resistance.
What are the types of vectors are there in biotechnology?
there are two types of vectors cloning vector and expression vectors.
What is the insert capacity of a lambda bacteriophage vector in DNA cloning?
We can insert about 5-25 kb sized foreign DNA in a lambda bacteriophage vector.
In the process of human gene cloning using recombinant plasmids what is the bacterial plasmid?
functions as a vector
