Answer:
4, 3, 5, 2, 1
Explanation:
The process of syhthesis of protein is called trancription.
- The proces sf transcription begin with the binding of RNA polymerase enzyme with a sequence of DNA called the promoter.
- RNA polymerase allows the unwinding of DNA bases forming a stable complex.
- In the next step, a Mg2+-dependent isomerization occurs, that produces a modified form of the open- promoter complex.
- RNA polymerase has one nucleoside triphosphate binding site which helps during elongation and binds any of the four common ribonucleoside triphosphates (rNTPs).
- Then a nucleophilic attack of the 3' hydroxyl (OH) present at the first nucleotide on the a - phosphorus gorup of the second nucleotide 5' triphosphate occurs that forms the first phosphodiester bond.
Hence, the correct order is 4, 3, 5, 2, 1.
Answer: diaphragm
Explanation:
The diaphragm separates the thoracic cavity from the abdominal and pelvic cavity.
The diaphragm is a sheet of internal skeletal muscle located below the thoracic cavity that houses the heart and lungs. Below the diaphragm is the abdominal cavity.
The diaphragm plays an essential function for respiration. When the diaphragm contracts, the volume of the thoracic cavity increases so that air is drawn into the lungs.
