    Cloning research is actively flourishing due to its various usages in several fields like industry, medicine, science, pharmacology, etc. cloning is the production of second generation which is identical to the parent in the phenotype and the genotype of the organism. Cloning in laboratories was stimulated by the cloning of bacteria as they are reproducing asexually by duplicating its genetic material and organelles to produce two daughter cells that are typically identical to the parent cell. Any cell can be cloned, except viruses, this article will be handling the reasons behind this. Cloning already happens in nature, from primitive organisms like bacteria as it is mentioned above to the higher ones like plants. Some Plants can clone itself like tubers, this type of plants’ stem can be reproducing an entire new identical organism in its favorable conditions, like potatoes. This happens due to the existence of the meristem in the potato as it has millions of undiffer...

Why are researchers developing Low Immunogenic wheat?

  The total global wheat consumption was 734.7 million metric tons, which increased by 759 million metric tons in 2021. As wheat was introduced into the human diet about 10,000–12,000 years ago. It has multiple health advantages such as maintaining healthy gut microbiota and obesity, in addition to it is nutritional value as it fills with vitamins, minerals, and fibers. Apart from its natural value, wheat protein's chemical structure is not fully digested by the pancreas. Wheat proteins, including non-gluten proteins, i.e., amylase/trypsin inhibitors (ATI), may trigger inflammatory immune reactions and disorders such as wheat allergies, CD, nonceliac gluten sensitivity (NCGS), fructose malabsorption, and irritable bowel syndrome (IBS). This article highlights the need for low immunogenic effect wheat that can provide a balanced and normal life.
