2. Dinosaurs appeared before mammals (a)
The right answers are : b. nitrogenous bases c. phosphates d. sugars.
Deoxyribonucleic acid (DNA) is the genetic information of most living organisms (on the other hand, some viruses, retroviruses, use ribonucleic acid (RNA) as genetic information).
- DNA is a polymer, made of units called nucleotides (or mononucleotides).
- The nucleotide consists of a phosphate + a sugar + a nitrogenous base. In DNA, the nucleotide is a deoxyribonucleotide (in RNA, the nucleotide is a ribonucleotide).
I would say C. eliminating government funding of research. without finding, scientists can't experiment, therefore all their research remains purely theoretical and isn't considered a discovery.
Hope this helps!
