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 transverse abdominal muscle (m. transversus abdominis) forms the deepest layer of muscles of the lateral abdominal wall. The muscle is part of the abdominal muscles, flattens the abdominal wall and brings the lower parts of the chest wall.At the top of the muscle starts from the inner surface of the cartilages of six lower ribs, and below-from the iliac crest, inguinal ligament and thoracolumbar fascia.he muscle is broad and flat, part of the abdomen. Start point is on the outer surface of the lower eight ribs. Pencils are sent to the oblique muscles down and in front (to the anterior abdominal wall), turn into aponeurosis.
