DNA and RNA

What is the structure of DNA?

• DNA is a double-stranded helix structure made up of nucleotides containing a sugar, a phosphate group, and a nitrogenous base.

• DNA is a single-stranded structure made up of amino acids

• DNA is a triple-stranded structure made up of lipids

• DNA is a double-stranded structure made up of proteins

What is the structure of RNA?

• RNA is a double-stranded molecule made up of nucleotides

• RNA is a single-stranded molecule made up of nucleotides that contain a sugar, a phosphate group, and a nitrogenous base

• RNA contains deoxyribose sugar instead of ribose sugar

• RNA does not contain any nitrogenous base

What are the differences between DNA and RNA?

• DNA is double-stranded, while RNA is single-stranded. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA uses the bases adenine (A), thymine (T), cytosine (C), and guanine (G), while RNA uses adenine (A), uracil (U), cytosine (C), and guanine (G). DNA is found in the nucleus of cells, while RNA can be found in the nucleus and cytoplasm.
