The Tactile DNA puzzle is a tool to teach visually impaired students the chemistry and structure of DNA. The puzzle contains the 4 different nucleotides (A,T,C,G) a phosphate piece and Deoxyribose ...

Each ribonucleotide base consists of a ribose sugar, a phosphate group ... Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone ...

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
