Frequently Asked Questions

How do you compare and contrast DNA and RNA?

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule while RNA is a single stranded molecule.

How is RNA different than DNA?

DNA vs. RNA. Structurally RNA is different from DNA in consisting of ribose as pentose sugar and Uracil as the pyrimidine group. RNA is not double helix as DNA, but it forms similar helical structures by being wound back due to base pairing. Just as in DNA, the bases are hydrogen bonded in RNA in these helical regions.

What are 3 major differences between DNA and RNA?

This arrangement of DNA strands is called antiparallel. The asymmetric ends of DNA strands are referred to as the5′ (five prime) and3′ (three prime) ends. One of the major differences between DNA and RNA is the sugar, with2-deoxyribose being replaced by the alternative pentose sugar ribose in RNA.

Which is better DNA or RNA?

DNA is a better genetic material than RNA as: 1. The 2-OH group present at every nucleotide in RNA is reactive and makes RNA labile and degradable. But, DNA is less reactive and structurally more stable.
