A wooden ladder usually have rungs made from wooden dowels with tapered ends. An aluminium ladder would have extruded aluminium rungs.
The ladder had 25 rungs in total. This can be calculated by adding the 7 rungs walked down to the 15 rungs climbed up, then adding the final 3 rungs. So, 7 + 15 + 3 = 25 rungs on the ladder.
The steps of a ladder are called rungs.

The spacing on ladder rungs should never be less than six inches or greater than 12 inches. The majority of 7 foot ladders have between 6 and 10 rungs.
If the rungs are perpendicular to one side of the ladder, then they must be parallel to the other side of the ladder. This is because if one side is perpendicular to the rungs, the other side, being parallel to the first side, will also be perpendicular to the rungs.

No; the rungs of a ladder and the sides of a ladder intersect. Skew lines do not intersect.
The enzyme helicase separates the nitrogen base pairs, or rungs, of the DNA ladder.
