It is the random-insertion process, that can interfere with existing genes, or carry an additional gene, that can be used as a process for genetic research. To use this process as a useful and controllable genetic tool, the two parts of the P element must be separated to prevent uncontrolled transposition.
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques.The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination".

The Krüppel protein is a transcription factor, and has been shown to act as a repressor.It functions in collaboration with other gap genes and their localized protein products to regulate the expression of the primary pair rule genes – even skipped (eve), hairy (h), and runt. [15]
A second version of the central dogma is popular but incorrect. This is the simplistic DNA → RNA → protein pathway published by James Watson in the first edition of The Molecular Biology of the Gene (1965). Watson's version differs from Crick's because Watson describes a two-step (DNA → RNA and RNA → protein) process as the central ...
He named this DNA–protein interaction (the original genetic code) as the "diamond code". [5] In 1954, Gamow created an informal scientific organisation the RNA Tie Club, as suggested by Watson, for scientists of different persuasions who were interested in how proteins were synthesised from genes. However, the club could have only 20 ...
Knowing the sequence of the protein encoded by a gene can allow researchers to apply methods that find similarities among protein sequences that provide more information than similarities or differences among DNA sequences. If the genes of a gene family encode proteins, the term protein family is often used in an analogous manner to gene family.

The generated protein is a sequence of amino acids. This sequence is determined by the sequence of nucleotides in the RNA. The nucleotides are considered three at a time. Each such triple results in addition of one specific amino acid to the protein being generated. The matching from nucleotide triple to amino acid is called the genetic code.
