Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...
Recombinant DNA (rDNA), or molecular cloning, is the process by which a single gene, or segment of DNA, is isolated and amplified. Recombinant DNA is also known as in vitro recombination . A cloning vector is a DNA molecule that carries foreign DNA into a host cell , where it replicates, producing many copies of itself along with the foreign DNA.

Usually the ultimate aim of expression cloning is to produce large quantities of specific proteins.To this end, a bacterial expression clone may include a ribosome binding site (Shine-Dalgarno sequence) to enhance translation of the gene of interest's mRNA, a transcription termination sequence, or, in eukaryotes, specific sequences to promote the post-translational modification of the protein ...
MicroRNAs, or miRNAs for short, are small (~22nt) segments of RNA which have been found to play a crucial role in gene regulation. One of the most commonly used methods for cloning and identifying miRNAs within a cell or tissue was developed in the Bartel Lab and published in a paper by Lau et al. (2001). Since then, several variant protocols ...
This image diagrams the procedure of subcloning as outlined to the left. In molecular biology, subcloning is a technique used to move a particular DNA sequence from a parent vector to a destination vector. Subcloning is not to be confused with molecular cloning, a related technique.
Functional cloning is a molecular cloning technique that relies on prior knowledge of the encoded protein’s sequence or function for gene identification. [1] [2] [3] In this assay, a genomic or cDNA library is screened to identify the genetic sequence of a protein of interest.
Chromosome jumping enables two ends of a DNA sequence to be cloned without the middle section. Genomic DNA may be partially digested using restriction endonuclease and with the aid of DNA ligase, the fragments are circularized at low concentration. [2] [3] From a known sequence, a primer is designed to sequence across the circularized junction.
