Answer/Explanation:
1. Both because RNA and DNA consist of Adenine, Uracil, Guanine, Cytosine, and Thymine which are all nucleic acids
2. R. RNA is usually single stranded while DNA is double stranded getting the name the "double helix"
3. D. DNA can usually be found in the nucleus of a cell but can sometimes be found in the mitochondrion of that cell which is outside of the nucleus
4. D. DNA got the name double helix because of its ladder like shape. The shape of DNA looks like ladders curling around a pole
5. Both. This is because both RNA and DNA consists of these nucleic acids but the acids that make then unique are the uracil in RNA and the thymine in DNA
6. Both. This is because all nucleotides consist of a phosphate, sugar, and a base. Thats what makes up a nucleotide
7. R. As it was said earlier, RNA has the same nucleic acids as DNA except uracil. DNA has thymine instead of uracil
8. D. DNA has thymine instead of uracil
9. Both. Both DNA and RNA are usually in the nucleus doing their jobs to help us function
10.D. DNA has sugar deoxyribose while RNA has sugar ribose.
11. Both. Both DNA and RNA are made up with nucleotides like thymine, uracil, adenine, and more
12. R. Only RNA has sugar ribose since DNA has sugar deoxyribose
