An individual has a genetic disorder in which their cell is not forming the correct protein structure for the cell membrane to a
Andru [333]

Answer:

The type of regulation of gene expression that would have the greatest chance of success is Posttranslational control (E).

Explanation:

The defect is found on the structure of the protein, this means that the process of formation of the protein and the codons responsible for each amino acid in the protein is in correct order, this set the transcriptional and translational process aside as being correct.

Therefore, the problem lies in the formation of secondary or tertiary structure of the protein which requires a good number of proteins also, wherein lies tha main problem in the cell membrane protein. Thus the regulation of the posttranslational process and correction of the proteins needed at this stage will give the best chance of success.

Cerrena [4.2K]
Nerve that supply bone accompany blood vessels through the nutrient foramen. They are responsible for the innervation of the bone as well as its outer covering, the periostem, the inner lining of the medullary cavity, the endosteum, and the medullary cavity. The nerves that innervates these structures are mainly sensory nerves that signal injuries to the skeleton.

Blood vessels enter the bones from the periosteum through the nutrient foramen (a small opening or hole in the bone), where the nutrient artery enters and where one nutrient veins exists in bone. The blood vessels supply nutrients and oxygen required by cells and remove the waste products from the cells of the bones.

Endosteum functions to cover and lines the bone, it is an incomplete layer of cells that covers all internal surfaces of the bone within the medullary cavity. It contains the Osteoprogenitor cells, osteoblasts and osteoclasts which are important cells of the bone.

Periosteum on the other hand is a fibrous, thick membrane covering the external surface of the bone, apart from the articular cartilage on the epiphysis. It is made of two layers: the outer fibrous layer of dense irregular connective tissues that protects the bone from external structures, anchors the blood vessels and nerves to the surface of the bone. It also  serves as an attachment site for ligaments and tendons. The inner cellular layer contains various cells which includes the osteoprogenitor, osteoclasts and osteoblasts.
