Final answer:
The incorrect statement about DNA is that it contains ribose sugar. DNA contains deoxyribose sugar, as opposed to RNA which contains ribose. The correct option is C.
Step-by-step explanation:
The incorrect statement about DNA is that c) DNA contains ribose sugar. DNA contains a five-carbon sugar called deoxyribose, not ribose, which is found in RNA (ribonucleic acid).
DNA's structure consists of two strands forming a double helix, where each strand is made up of nucleotides. Each nucleotide within DNA is composed of three components: a nitrogenous base, a deoxyribose sugar, and a phosphate group.
These nucleotides are joined to create a backbone of sugar-phosphate molecules for the DNA strand. During cell division, DNA undergoes replication where each strand of the double helix serves as a template for creating a new complementary strand.
