Front

What are nucleotides?

Back

The building blocks of DNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the role of the sugar-phosphate backbone in DNA?

Back

It provides structural support and stability to the DNA molecule.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains Thymine, while RNA is single-stranded and contains Uracil.
