Molecular Cloning vs. Reproductive Cloning

Molecular Cloning– Molecular cloning is a group of experimental techniques used in molecular biology to put together recombinant DNA molecules and control how they replicate inside hosts. The term “cloning” describes a process in which one molecule is replicated to create a population of cells with identical DNA molecules. DNA sequences from two separate creatures are often used in molecular cloning: the species from which the DNA to be cloned originates and the species that will act as the living host for the duplication of the recombinant DNA. Many contemporary fields of modern biology and medicine depend heavily on molecular cloning techniques.

Reproductive Cloning– The intentional creation of individuals who are genetically identical is known as reproductive cloning. Each freshly created clone is a duplicate of the original. Twins that are monozygotic (identical) are biological clones. Every cell in the clones’ bodies has identical genetic material in the nucleus, which is where the chromosomes are located. Thus, the DNA and genes in the nuclei of cells from two clones are identical.

The energy-producing “factories” called mitochondria in all cells, including eggs, also house some DNA. The cytoplasm, the part of a cell outside the nucleus, is where these structures are located. Mitochondria have unique DNA and can multiply on their own. Although the term “clones” is also used to describe individuals with identical nuclear DNA and distinct mitochondrial DNA, true clones have identical DNA in both the nuclei and mitochondria.

What is it used for

Molecular Cloning– To treat a hereditary problem or acquired disease, gene therapy entails introducing a functional gene to cells that lack it. Gene therapy can be split roughly into two types. The first causes a lasting genetic change in the entire body as well as future generations when germ cells, such as sperm or eggs, are altered.

Cloned genes may be injected into organisms to create transgenic creatures, also known as genetically modified organisms, after being described and altered to provide signals for optimal expression (GMOs). A number of GMOs have been developed for commercial use, including herbicide-resistant crop plants, fluorescent tropical fish (GloFish) for home entertainment, and animals and plants that produce pharmaceuticals or other compounds (pharming). Most GMOs are created for purposes of basic biological research (for instance, transgenic mice).

Reproductive Cloning– An artificial or natural uterus is used to implant a cloned embryo during reproductive cloning. A fetus is formed from the embryo and is subsequently carried to term.

There is no conclusive scientific proof to date that anyone has cloned human embryos.

Cloning is mostly done to create large numbers of organisms with desirable traits, such as a prize-winning orchid or a genetically modified animal that can manufacture human insulin in the case of sheep.

The Origins of Cloning

Molecular Cloning-When restriction endonucleases were identified in the 1970s, the first cloning studies were conducted. DNA is cut like a pair of scissors by restriction endonucleases, which cleave and cut DNA with specificity.

With the aid of restriction endonucleases, researchers were able to extract a specific DNA fragment—typically a gene—and insert it into a vector for copying. The cloned DNA segment can potentially undergo modifications during the procedure. Cloning evolved to become a key molecular biology technique that forms the basis of most of what is understood about genetics today.

Science fiction has frequently and particularly exploited human cloning to explore the contentious issues surrounding identity.

Reproductive Cloning -A publication published in 1997 in the journal Nature with the short title “Viable offspring produced from fetal and adult mammalian cells” introduced the world to Dolly, the Sheep.

The scientific paradigm of the day was defied when a mammal was cloned. The result prompted ominous and imaginative predictions, including the cloning of humans. Infections would be avoided. Lost children reborn. The influence of cloning on basic research has surpassed expectations two decades after Dolly was born on July 5, 1996, while the actuality of what is formally referred to as nuclear transfer—the type of cloning performed with Dolly—has mostly disappeared from the public memory.

In conclusion, it is safe to say that the future of molecular cloning is bright, while reproductive cloning looks bleak. Only time will tell what the future of reproductive cloning holds.
