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 internal abdominal oblique muscle ends at the bottom edge of the rib cage, the rectus sheath (fibrous tissue that covers the abdominal muscles), and the pubic crest (an area in the lower-front of the pelvis). The internal abdominal oblique muscle is located closer to the skin than the transverse abdominal muscle.This muscle supports the abdominal wall, assists in forced respiration, aids in raising pressure in the abdominal area, and rotates and turns the trunk with help from other muscles.he internal abdominal oblique muscle is located closer to the skin than the transverse abdominal muscle.
