ANDROGEN-INSENSITIVITY SYNDROME
These individuals have female external sexual characteristics. Vagina ends blindly and that the uterus, oviducts, and ovaries are absent.
 Inside the abdominal cavity, a pair of testes produce levels of testosterone normally seen in males. 
Woman with androgen-insensitivity syndrome contain an X and a Y chromosome. 
Testosterone bind to an androgen receptor. This receptor is defective in females with androgen-insensitivity syndrome.
The gene for the androgen receptor is located on the X chromosome

Sometimes the S1 nuclease will not digest the single stranded regions completely, so the transcript appears to be a little longer than it really is, But another method, called primer extension, can tell the 5’-end (but not the 3’-end) to the exact nucleotide
