Question

dna looks sort of like a weird ladder. the
ungs\ of the ladder are the
□ nitrogenous bases
□ phosphate groups
□ deoxyribose sugars
rewatch

Explanation:

DNA's double helix structure is like a ladder. The "rungs" are formed by paired nitrogenous bases (A-T, G-C) that connect the two sugar-phosphate backbones. Phosphate groups and deoxyribose sugars make up the ladder's sides, not the rungs.

Answer:

nitrogenous bases
