 Cloning and Recombinant DNA technology are same: Dilemma to be resolved

A clone is a group of unique cells or organisms that derive from a single progenitor in biology.
Because cell replication creates identical daughter cells every time, the individuals of a clone are
genetically identical. The term "clone" has been extended to recombinant DNA technology
(RDT), which allows scientists to make multiple copies of a single segment of DNA, such as a
gene, resulting in identical duplicates that make up a DNA clone. In practice, a DNA fragment is
inserted into a small DNA molecule, which is then allowed to proliferate inside a primitive live
cell such as a bacterium. A DNA vector is a tiny self-replicating molecule (carrier). Plasmids
(circular DNA molecules derived from bacteria), viruses, and yeast cells are the most commonly
used vectors. Plasmids are not part of the main cellular genome, but they can include genes that
provide the host cell valuable characteristics including drug resistance, mating ability, and toxin
production. They're small enough to manipulate easily in the lab, and they'll also carry extra
DNA that has been spliced into them. Uses of cloning are:

 With biomedical procedures, DNA cloning can be utilised to create proteins like insulin.

 It's employed to develop recombinant variants of the non-functional gene in order to
figure out how the regular gene works. This is also used in gene therapy.

 It aids in determining the impact of a mutation on a certain gene.

Recombinant DNA refers to DNA molecules from two different species that are introduced into
a host organism to create new genetic combinations useful in science, medicine, agriculture, and
industry. Because the gene is at the core of all genetics, laboratory geneticists' primary purpose is
to extract, define, and modify genes. Although isolating a sample of DNA from a group of cells
is very simple, locating a specific gene within this DNA sample is comparable to finding a
needle in a haystack. Consider that each human cell has about 2 metres (6 feet) of DNA. As a
result, a tiny tissue sample can contain thousands of kilometres of DNA. Recombinant DNA
technology has made it possible to isolate a single gene or other section of DNA, allowing
researchers to establish its nucleotide sequence, investigate its transcripts, alter it in extremely
specific ways, and reintroduce the transformed sequence into a living organism. Uses of RDT
are:

In agriculture, recombinant DNA technology is frequently used to produce genetically
modified organisms such as Flavr Savr tomatoes, Golden Rice, Bt-cotton to protect plants
from bollworm, and many others. Advanced Biotechnology

Human insulin is made using recombinant DNA technology in the pharmaceutical
industry.

In clinical diagnosis.

What students need to grasp is that recombinant DNA technology and DNA cloning are not the

We at Experiome offer hands-on training and learning opportunities to students in the area of
recombinant DNA technology.

Use of Genetically Engineered Cyanobacteria in Therapeutics Spirulina is a blue-green algae or cyanobacteria which is found in high-salt alkaline water, subtropical and tropical places such as America, Mexico, Asia, and Central Africa.   It’s asexual reproduction reduces the danger of gene escape into the food chain, as well as the accompanying food security and regulatory concerns. It contains a lot of macro and micronutrients, important amino acids, proteins, lipids, vitamins, minerals, and antioxidants. With these characteristics, photosynthetic cyanobacteria have been used in a variety of industries, including food, health, and pharmaceuticals. It is consumed mainly in central Africa and later NASA started using spirulina as a nutritional supplement for astronauts on space missions. It gained attention for therapeutic benefits like hypercholesterolemia, hyperglycerolemia, cardiovascular diseases, inflammatory diseases, allergies, cancer and viral infections.  Spirulina, as a plan

Ethics and Requirements of Plant Tissue Culture Laboratory | Experiome Inc

  Ethics and Requirements of Plant Tissue Culture Laboratory Plant tissue culture generally refers to   in vitro culture of all plant parts under sterile conditions. Basic facilities are must in the laboratory where tissue culture technology is to be performed. This includes general cleaning and media preparation, sterilization, storage, sterile transfer, observation / data acquisition, and environmentally controlled incubator or culture room areas. The most important work area is the Cultural Transfer Office, where   core activities take place. Plant tissue culture should be cultured for a specified period of time under well-controlled temperature, humidity, airflow, and light quality. Plant culture techniques require a variety of organic and inorganic chemicals to prepare the   culture medium. The growing room is an equally important area where plant cultures are maintained under controlled environmental conditions for optimal growth. After in vitro culture of plants they are transfe

Macronutrients or micronutrients are the two types of nutrients. Requirements of macronutrients including fats, proteins, and carbohydrates are relatively higher to that of micronutrients including several vitamins and minerals. In comparison, if the amount of micronutrients in the diet is low, it has an impact on the child's physical and mental development. Vitamin A is a lipid-soluble vitamin that is required for cell growth, metabolism, immunological function, eyesight, and reproduction. It is absorbed in the duodenum and stored in hepatic stellate cells, as well as in adipose tissue and the pancreas in small amounts. Vitamin A is found naturally in dark leafy greens, orange-colored vegetables, milk products, liver, and fish. Vitamin A intake should be around 200 micrograms per day for children aged 1 to5, 70
