Generally it is called emigration.
That is often called patriotism, but it is sometimes called nationalism.
Repressor
A repressor protein binds to the operator region of DNA to inhibit the binding of RNA polymerase, blocking transcription of the gene. This mechanism is common in prokaryotic organisms to regulate gene expression by preventing transcription of specific genes when they are not needed.
The protein that hair is composed of is called keratin.
A segment of DNA that codes for a protein is called a gene, or an exon.
Fingernails and hair (and claws, hooves and horns on animals) is composed of a protein called "Keratin".
Hair is primarily made up of a protein called keratin.
Hair is composed of a protein called keratin, which is produced by hair follicles in the skin.
A segment of DNA on a chromosome that controls the production of a protein is called a gene. Chromosome a cellular structure that contains DNA.
If it consists only of these two components it is a virus.
They are composed of a protein called keratin.
Arthropod have exoskeleton. The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer.
A segment of a gene that codes for a protein is called an exon. Exons are the parts of a gene that are ultimately expressed as proteins after being transcribed and translated. They are interspersed with non-coding regions called introns.
