Agent Orange is a herbicide and defoliant chemical. It is widely known for its use by the U.S. military as part of its herbicidal warfare program, Operation Ranch Hand, during the Vietnam War from 1961 to 1971. It was a mixture of equal parts of two herbicides, 2,4,5-T and 2,4-D. The chemical damaged the health of people who came into contact with it as well as extensively contaminated the environment. Environment: Agent Orange caused enormous environmental damage in Vietnam. Over 3,100,000 hectares (31,000 km2) of forest were defoliated. Defoliants eroded tree cover and seedling forest stock, making reforestation difficult in numerous areas. Animal species diversity sharply reduced in contrast with unsprayed areas.
Toxicology: Due to its fat-soluble nature, agent orange/dioxin enters through physical contact or ingestion. Dioxin easily accumulates in the food chain. Dioxin enters the body by attaching to a protein called the aryl hydrocarbon receptor (AhR), a transcription factor. …

Can we actually "build" DNA molecules with a set sequence?

Yes we can. There is whole new branch of biology for this, SYNTHETIC GENOMICS. Synthetic genomics is a nascent field of synthetic biology, that uses aspects of genetic modification on preexisting life forms or artificial gene synthesis to create a new DNA or entire new life forms. Craig venter and his team has created new bacteria with synthetic genome. As a summarized article, read:After 20 Year Quest, Biologists Create Synthetic Bacteria With No Extra Genes


What is Polymorphism ?

In Biology, Polymorphism is the variation within a population. Polymorphism is the occurrence of one or more distinct individual with characteristic difference in phenotype within the members of same species. Polymorphisms occurs due to genetic variation (which may be a result of mutation or random mating) or due to environmental factors (Geographical distribution) Polymorphisms can be detected with Morphological markers (different morphological parameters), DNA markers (RFLP, AFLP, SSR, SNP etc.), biochemical markers (Isozymes).

Human Hair Color - Biochemistry and Genetics

1. Hair is made up of Keratin , but keratin is colorless so what gives our hair the unique color?
2. The answer is Melanin.
3. Melanocyte gland produces two different kinds of melanin. One is "Eumelanin" and other is "Pheomelanin".
4. Eumelanin is responsible for Black and Brown color.
5. Pheomelanin is responsible for Red and Orange color.

So, Which gene controls their concentration in our hair?

1. MC1R - MC1R gene translates into Melanocortin 1 Receptor protein, which controls the production of this two melanin.
2. If MC1R is active in a cell, it stimulates the production of Eumelanin, while if the MC1R gene is blocked or polymorphic, it will stimulates the production of Pheomelanin.

What is the best way to increase good gut bacteria?

As a popular, Probiotics like yogurt can help someone to create a good gut microbiome. Along with this I want to add, there is another Term Known as “PREBIOTIC”. Most of the people are unaware about this term. Prebioticsare substances that induce the growth or activity of microorganisms that contribute to the well-being of their host. Prebiotics by definition are a type of non-digestible fiber compounds which are found in different plants. In simple term” Prebiotics are specific food or like fertilizer to increase the amount of specific bacteria in your gut”. So increase the intake of prebiotics in your diet to increase the good bacteria in your gut. Table Source: Wikipedia.
