Which of the following is NOT found in every nucleic acid?

Question

a. ribose

b. phosphate group

c. single-ring base

d. double-ring base

e. All of these are characteristic of every nucleotide

only one choice can be made.

Answer 1

a c d. It depends if you are refering to DNA, RNA or both. DNA contains a deoxyribose as its 5 carbon sugar while RNA contains ribose as its 5 carbon sugar. Some nucleotides have single ring bases while others have double ring bases. The single ring bases are pyrimidines and include C and T in DNA and C and U in RNA. The double ring bases are the purines that are A and G in both DNA and RNA

Answer 2

a. Ribose
c. Single-ring base
d. Double-ring base

This assumes that you include DNA and RNA nucleic acids. DNA contains deoxyribose, not ribose. Also, some nucleic acids contain a double-ring purine and others a single-ring pyrimidine. But any one kind of base is not in all nucleic acids.

Answer 3

a. Ribose
AND
c. Single-ring base
AND
d. Double-ring base.

All nucleotides are composed of three parts, a nitrogenous heterocyclic base (this is a single-ring base OR a double-ring base), a pentose (this is either ribose OR deoxyribose), and at least one phosphate group.

The answer is A, C, and D.

Answer 4

I think perhaps arrangement means the order the atoms are in. For examples, carbohydrates would be carbon first, hydrogen second with double the amount of carbon, and oxygen last with the same amount of carbon (so basically explaining its form (carbohydrates are C6 H12 O6) Types or catagories would me mono,poly and di saccarides for carbohydrates Uses collectively or by types might be how its used. Carbohydrates are an energy molecule, lipids are for storage i think etc etc I hope this helps ! Good luck :)

Answer 5

a in RNA you have ribose and in DNA deoxy ribose

Answer 6

B
