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 transversus abdominis is the deepest abdominal muscle. It sits below the oblique muscles. It acts as an abdominal support belt and plays a major role in maintaining posture. Most abdominal exercises involve the transversus abdominis; however, the transverse abdominal exercises below focus on it in particular.These exercises are excellent for improving core stability and strength and preventing lower back pain.he stability ball bridge is a stabilizing exercise that works the transversus abdominis muscles. This is a good exercise for users of varying experience because the user can vary the amount of time the bridge is performed for. More experienced users may hold the bridge for a longer period than less experienced users.
