**Instructions:**

1. **Task**: Draw a replication fork in the space below. Be sure to label the 5' and 3' ends of the DNA on both strands.

(Note: The diagram is not provided in the image. The text merely instructs to draw a replication fork and ensure the 5' and 3' ends of the DNA strands are labeled correctly.)

### Explanation for Drawing a Replication Fork:

A replication fork is a structure that forms within the long helical DNA during DNA replication. It is created by helicases, which break the hydrogen bonds holding the two DNA strands together. The replication fork is the active area where DNA replication takes place. Here are the key components to include in your drawing:

1. **DNA Strands**: Represent the double helix unwinding into two single strands.

2. **Leading and Lagging Strands**:
   - **Leading Strand**: Synthesized continuously.
   - **Lagging Strand**: Synthesized discontinuously in short sections called Okazaki fragments.
   
3. **Labeling the Ends**:
   - Identify and label the 5’ (five prime) and 3’ (three prime) ends of both the leading and lagging strands. DNA strands are antiparallel, meaning one strand will run 5’ to 3’ and the complementary strand will run 3’ to 5’.

### Example of the Correct Labels:
- The leading strand's newly synthesized fragment runs from 5’ to 3’ towards the replication fork.
- The lagging strand's newly synthesized Okazaki fragments run from 5’ to 3’ away from the replication fork.

**Note**: Make sure your drawing clearly shows the directionalities and the separation of the double helix into a replication fork structure.
