The 2 scientists that constructed the ladders of DNA +1
James Watson and Francis Crick in 1953
Built a model
Watson and Crick built a DNA model in the shape of a double helix, which resembles a twisted ladder. The double helix structure of DNA consists of two strands that are twisted around each other to form a stable and efficient way to store genetic information.
The shape is a helical structure known as the double helix, which is the twisted ladder-like form of DNA. Rosalind Franklin's x-ray diffraction images provided crucial evidence for the structure, and Watson and Crick built a model to accurately represent the DNA molecule's double helix shape.

Speculation on the reason it was built range from human sacrifice to astronomy.
A loft ladder, otherwise known as an attic ladder, is a retractable ladder that is built in to the floor of the attic. An extension ladder is a free standing ladder that can be moved around at will.
The answer is a fish ladder.
