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 sides of the DNA double helix ladder is composed of alternating phosphate groups and deoxyribose sugars.
Double helix.
DNA is double stranded. It is described as a double helix, kind of like a twisted ladder.
A molecule of DNA consists of two strands of various chemical compounds that other chemicals carrying genetic information join together, much like ladder rungs hold ladder rails apart. The two strands joined with thousands of rungs look like a long rope ladder that has been twisted into the shape of a spiral, called a double helix.
The sides of the DNA ladder is composed of sugar and phosphate. 4 bases that make up the rungs of the DNA ladder are A, T, G, and C. The shape of the DNA is a double helix or twisted ladder.
The twisted ladder shape of DNA is called a double helix.carbohydrate
Yes! DNA is a double helix strand that is a full ladder. RNA is that ladder cut in half!

A double-cleat ladder or two or more separate ladders must be provided when ladders are the only means of access / exit from a work area with 25+ workers
