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.
The four main abdominal muscle groups that combine to completely cover the internal organs include: 1  transversus abdominis â the deepest muscle layer. 2  rectus abdominis â slung between the ribs and the pubic bone at the front of the pelvis. 3  external oblique muscles â these are on each side of the rectus abdominis.
