Expression vectors (or Constructs)Cloning vectors provide a backbone for the DNA insert to be reproduced and propagated in bacteria; however, these vectors are only useful for storing a genetic sequence. By themselves, they are incapable of allowing for transcription and translation of the gene into a functional protein product (Li et al., 2017).The expression vectors are vectors which act as ve..

Types of Cloning VectorsCloning is generally performed using Escherichia coli, and cloning vectors in E. coli include plasmids, bacteriophages, cosmids, and bacterial artificial chromosomes (BACs). Some DNA, however, cannot be stably maintained in E. coli, for example very large DNA fragments. In this case, other organisms such as yeast may be used. Cloning vectors in yeast include yeast artific..

Rolling-Circle ReplicationReplication by the RC mechanism has to be unidirectional, and it is considered to be an asymmetric process because synthesis of the leading strand and synthesis of the lagging strand are uncoupled (reviewed in references 69, 84, 108, 150, 150a, and 228). One of the most relevant features of RC replication is that the newly synthesized leading plus strand remains coval..

Plasmids are extrachromosomal DNA elements with characteristic copy numbers within the host. These replicons have been found in species from the three representatives of the living world, namely, the domains Archaea, Bacteria, and Eukarya (318). Plasmids may constitute a substantial amount of the total genetic content of an organism, representing more than 25% of the genetic material of the cell..
