The enzyme DNA polymerase works only in the 5′ to 3′ direction. How does this affect the leading strand and the lagging strand?
aliina [53]

Answer:

B

Explanation:

DNA replication is semiconservative- meaning the old template strand will form a double helix with the newly synthesized strand. The DNA polymerase can only replicate DNA in the 5’ -> 3’ direction on a DNA strand. However, because the two strands of a DNA double helix run antiparallel (and they are replicated together), then during replication, one strand will be oriented in the opposite direction (i.e 3’ -> 5’ direction).

Because DNA polymerase requires a primer to begin replication, the leading strand will require one primer, because replication on this strand occurs continuously. On the lagging strand, many primers are required because replication is done piecemeal forming fragments called Okazaki fragments. The fragments are later joined by DNA ligases.

Oxygen and Carbon Dioxide exchange as a result of the interaction of which two body systems
miskamm [114]

Answer:

4

Explanation:

The circulatory system includes the blood that has picked up the carbon dioxide from all of the respiring tissues and who also delivered oxygen to them to continue respiring.

The blood will then reach the lung where the carbon dioxide that the tissues released is exchanged for oxygen in the alveoli.

* Blood cells isn't an organ system which makes 1 incorrect.

* Digestive system will in no way bring the blood to the lungs or away from it. This is the circulatory system's job. So 2 is incorrect.

*Lastly, lungs are organs and the question asks for organ systems. So 3 is incorrect.
