Leg hair follicle it pushed older cells out and that is what becomes the leg hair. After the older cells become hard and leave the follicle, they form a hair shaft. The hair shaft is mostly made up of dead tissue and a protein that is known as keratin. It is said that hair growth occurs during the "growing" phase of the follicle, and then retained as dead club hair during the "resting" phase. The old club hair might be lost within the following "growing" phase. Men are seen to be much hairier than women, even though men and women are much
YqaJ protein domain YqaJ protein domain In molecular biology, the YqaJ refers to the YqaJ/K domain from the "skin" prophage of the bacterium, "Bacillus subtilis". This protein domain, often found in bacterial species, is actually of viral origin. The protein forms an oligomer and functions as an alkaline exonuclease, or in simpler terms, an enzyme that digests double-stranded DNA. It is a reaction which is dependent on Magnesium. It has a preference for 5'-phosphorylated DNA ends. It thus forms part of the two-component SynExo viral recombinase functional unit. The function of this protein domain is to digest DNA. Most viruses, inject their host
