Similar to a standard ladder but wider and incorporating a center rail to allow for two-way simultaneous traffid. (OSHA rule: Always use double-cleated ladders when ladders are the only way to enter and exit a working area with 25 or more employee and when ladders are used for two-way simultaneous traffic.) But try to find one with web search and you are in for a hard time.

The shape of a DNA molecule is called a double helix.
The two sides of the DNA double helix ladder are made up of nucleotides. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). The nitrogenous bases on opposite strands pair together through hydrogen bonding (adenine with thymine, and guanine with cytosine), holding the two sides of the ladder together.
DNA is a double helix, or a twisted ladder.
The twisted ladder shape of a DNA molecule is called a double helix. The double helix structure consists of two strands that are twisted around each other, forming a shape resembling a twisted ladder or spiral staircase. This iconic structure was first described by James Watson and Francis Crick in 1953, revolutionizing our understanding of genetics.
