“Another difference between DNA and RNA is that RNA contains ribose, rather than deoxyribose.”

“The backbone of both strands in the double helix is a chain of linked phosphate and deoxyribose molecules.”

“A nucleotide is a combination of a ribose or deoxyribose sugar, a purine or pyrimidine base, and a phosphate group.”

“Scientists conducted a thorough analysis of the ancient fossil, confirming the presence of deoxyribonucleic acid within its deteriorated remains.”

“Each chromosome carries a single strand of deoxyribonucleic acid that threads together about 1,000 genes.”

“Within the nucleus are chromosomes that contain DNA, or deoxyribonucleic acid, genetic material unique to each individual.”
