The cloning capacity of pBR322 vector is 1-5kb.
pBR322 was the first cloning vector to be discovered in 1977. It was instrumental in the development of modern genetic engineering techniques.
pBR322 has one multiple cloning site, which is located within the tetracycline resistance gene. This region allows for the insertion of foreign DNA fragments for cloning purposes.
pBR322 is a plasmid vector that contains an origin of replication for replication in E. coli, as well as antibiotic resistance genes for ampicillin and tetracycline. It also has unique restriction sites for easy insertion of foreign DNA. Once the foreign DNA is inserted into the vector, the plasmid can be transformed into E. coli cells where it replicates and expresses the inserted DNA.
pBR322 is one of the most used cloning vectors in molecular biology. Cloning vectors, best-known as plasmids, are autonomously replicating DNA units into which DNA fragments can be inserted for gene cloning. Genes taken up by these plasmids are multiplied (or cloned) as the vector replicates, to yields numbers suitable for molecular analysis. The most versatile and well-known plasmid is certainly pBR322 (in fact was one of the first ever used in gene cloning techniques) and has genetically tailored cutting sites into which DNA can be inserted without affecting plasmid self-replication. pBR322 general characteristics are: a) Size: 4.3 kb; b) Replicon: ColE1, relaxed; c) Selective markers (resistance): Amp and Tet; d) Single sites (enzymatic restriction single sites): Ava I, Pst I, BamHI, PvuII, ClaI, SalI, EcoRI, and HindIII.
MCS (Multiple Cloning Site) is not a cloning vector itself, but rather a region within a vector that contains multiple restriction sites for inserting DNA fragments during the cloning process. Common vectors that contain an MCS include plasmids and phage vectors.

Yes, pBR322 contains EcoRI restriction sites. Specifically, there are two EcoRI sites located within the plasmid's multiple cloning site (MCS), allowing for the insertion of foreign DNA. This feature makes pBR322 a useful vector for cloning purposes in molecular biology.
pBR322 advantages is it widely used for the analysis of prokaryotic transcription and translation as well as topological changes in DNA conformation. then the disadvantage is it has only few cloning sites and the selection procedure is therefore time consuming.
The insert capacity of a cosmid vector is about 35-45 kb.
The pBR322 vector is a plasmid commonly used in molecular biology. It contains genes for ampicillin resistance and tetracycline resistance, allowing selection of transformed bacteria. The multiple cloning site (MCS) allows insertion of DNA fragments for various experiments. The plasmid replicates autonomously in a host cell, generating multiple copies of itself.

We can insert about 5-25 kb sized foreign DNA in a lambda bacteriophage vector.

You can add maximum 70-100 kb of genetic material in a P1 phage vector.
MCS (Multiple Cloning Site) is not a cloning vector itself, but rather a region within a vector that contains multiple restriction sites for inserting DNA fragments during the cloning process. Common vectors that contain an MCS include plasmids and phage vectors.
The host organism into which a cloning vector is placed is called a "host cell." This host cell provides the necessary cellular machinery for replicating the cloning vector and expressing the inserted DNA.
