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 intercostal muscles lie between the ribs. When you exhale, these muscles contract, and in conjunction with the abdominal muscles, the lungs contract and air is forced up v â¦ ia a positive pressure gradient.here are three levels of intercostal muscles all situated between the ribs. The layers are named according to depth into the thorax, the outer (or external) intercostal being the most superficial the inner (or internal) intercostals being in the middle and the innermost intercostal being the deepest.
