What is gene editing & genetic engineering?
Genetic engineering is a process by which the genes of a living thing are modified, or changed. Genes are tiny units that carry information about an organism. They make up the material called DNA, which is found in the cells of every living thing. Genetic engineering dates to 1973, when two American scientists cut and rejoined bits of DNA.
The artificial manipulation of one or more genes in order to modify an organism is called genetic engineering. The term genetic engineering initially encompassed all of the methods used for modifying organisms through heredity and reproduction.
By definition, genetic engineering is the direct altering of an organism's genome. This is achieved through manipulation of the DNA. Doing this is possible because DNA is like a universal language; all DNA for all organisms is made up of the same nucleotide building blocks.
Genetics is the study of heredity, or how certain features pass from parents to their offspring, or young. Every kind of plant and animal produces young of its own species, or type. The young resemble their parents. But offspring are not usually exactly the same as their parents.
Genetic engineering, sometimes called genetic modification, is the process of altering the DNA in an organism’s genome. This may mean changing one single base (A, T, C or G) to alter the function of a gene or deleting or inserting a whole gene or region of DNA. Read about the different types of genome edits here.
Genetic engineering, also called gene editing or genetic modification, is the process of altering an organism's DNA in order to change a trait. This can mean changing a single base pair, adding or deleting a single gene, or changing an even larger strand of DNA.
Genetic engineering is the process of modifying an organism of a genetic level- for example, inserting or modifying a gene into an organism is genetic engineering. However, steroids are simply compounds (like vitamins or hormones) that can affect bodily function- they don't modify your body on a genetic level!
