Answer:

The correct answer is c. both strands of a molecule act as templates.

Explanation:

One DNA strand is called the leading strand and the other lagging strand. The leading strand is synthesized continuously but lagging strands are synthesized in a discontinuous way.  

So due to discontinuous replication of lagging strand small fragments of DNA are synthesized which are called Okazaki fragments. Then these fragments are sealed by ligase enzymes. So the correct answer is c.

In the diagram, how many angles are alternate exterior angles with angle 5?
andriy [413]

Explanation:

We have attached a figure that shows the diagram of the given equation.

We need to find how many angles are alternate exterior angles with angle 5?

We know that an exterior angle is the angle that is made outside of the shape and an alternate angle is the angle opposite of a transversal line of another angle.

From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
