The interior supporting structure of the human body is bone. At birth, it comprises of about 270 bones. This number decreased gradually to 206 by maturity, due to fusion of bones. The bone mass reaches peak around the age 21. The skeletal system is separated into appendicular and axial. The skeletal system is made up of cartilages, bones, and ligaments. They are linked together to develop a stretchy and strong basis for the body. The forerunner of most bones during the embryonic development is termed as the cartilage. It performs like a precursor to form a fully developed skeletal system. At the joint, the bones are clamped together by the ligaments. The tendons help in attaching the muscle to the bone.

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase

Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
