The inducer binds with the repressor, forming a repressor-inducer complex. This complex prevents the repressor from binding with the operator gene of the operon. This frees the operator gene so that the RNA polymerase can move from the promoter to the structural genes.
The transverse abdominal muscle (TVA), also known as the transverse abdominis, transversalis muscle and transversus abdominis muscle, is a muscle layer of the anterior and lateral (front and side) abdominal wall which is deep to (layered below) the internal oblique muscle.he transverse abdominal, so called for the direction of its fibers, is the innermost of the flat muscles of the abdomen, being placed immediately beneath the internal oblique muscle.
Choosing from the three layered muscles of the lateral abdominal wall, the external abdominal oblique remains the most superficial yet ironically the strongest. The fibers of the muscle are directed medially and inferiorly to amplify its contraction.he deepest of the muscles of the abdomen is the transversus abdominis. The long fibers of this muscle are put to use across the abdominal wall, laterally. A large sheath encases the long rectus abdominis in its entirety.
