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 deep muscles of the posterior compartment of the leg are the popliteus, tibialis posterior, flexor digitorum longus and flexor hallucis longus. The gastrocnemius calf muscle is the most superficial of the calf muscles. It inserts onto the heel bone via the Achilles tendon. The gastrocnemius muscle flexes the foot at the ankle joint â that is it acts to point the foot downwards by bending it at the ankle joint, such as when you stand on your toes. This action is known as plantar flexion. The gastrocnemius also flexes the leg at the knee joint.
