In the respiratory system, the movement of respiratory gases in the blood between the lungs and the cells of the body is known as gas exchange.

Gas exchange involves two main processes: external respiration and internal respiration. External respiration is the exchange of gases between the lungs and the blood, while internal respiration is the exchange of gases between the blood and the body's cells. The movement of respiratory gases in the blood between the lungs and the cells of the body is known as gas exchange in the respiratory system. During this process, oxygen ([tex]O2[/tex]) is transported from the lungs to the body's tissues and carbon dioxide ([tex]CO2[/tex]) is transported from the body's tissues to the lungs to be exhaled. Gas exchange occurs in the alveoli of the lungs, which are small sacs surrounded by capillaries, where oxygen and carbon dioxide diffuse across their thin walls.

The oxygen diffuses into the blood while the carbon dioxide diffuses out of the blood and into the alveoli to be exhaled. The blood then carries the oxygen to the body's tissues where it is used for cellular respiration, and carries the carbon dioxide back to the lungs to be exhaled.

The following is common to both factor-dependent and factor-independent transcription termination is both types of termination occur following a pause by the polymerase

Factor-dependent and factor-independent are the two types of transcription termination. In factor-independent transcription termination, a DNA sequence containing a GC-rich inverted repeat is essential. The sequence can be followed by a stretch of T's, which are complementary to the A's in the transcript. When a polymerase reaches the terminator sequence, the RNA polymerase transcribes the inverted repeat sequence. As a result, the mRNA folds back on itself, forming a hairpin structure. The formation of a hairpin loop causes the RNA polymerase to pause, resulting in termination.

On the other hand, factor-dependent transcription termination is based on a specific termination factor, Rho. Rho is a protein that binds to the mRNA and travels along it. As the RNA polymerase approaches a termination site, Rho binds to the RNA and triggers the termination process. Therefore, the two transcription termination types have different mechanisms. The only common feature of the two transcription termination types is that they occur following a pause by the polymerase. This is what the two transcription termination types have in common.
