ANSWER
The DNA ( Deoxyribose nucleic acid) molecule is composed of Nucleotide ,the deoxyribose sugar ,Nitrogen base and Phosphate group.
OR
The RNA (Ribonucleic acid) is composed of Nucleotides,ribose sugar ,Nitrogen base and Phosphate group
The sugar used in both nucleic acid is Pentose....
The the 7 molecule is composed of the nucleotide and phosphate groups sugar
When the base thymine combines with the sugar deoxyribose and a phosphate group, the nucleotide formed is named a) thymidine b) deoxythymidine 5'-monophosphate c) thymidine 5'-monophosphate deoxythymidine e) thymidine deoxymonophosphate
Adenine 0-P=0 Thymine Lo O=r-o Sugar-phosphate backbone Sugar-phosphate backbone Cytosine O-P=0 Guanine 0 NH O=P-O 0-- Nitrogenous bases Where are the hydrogen bonds found in this DNA molecule? between C and H in the nucleotide cytosine between H in cytosine and O in guanine between N and H in the nucleotide containing guanine between H in guanine and N in cytosine
In a triphosphate nucleotide, phosphoanhydride bonds are used to link: two phosphates together a phosphate to ribose or deoxyribose a nitrogenous base to ribose or deoxyribose the sugar of one nucleotide to the phosphate of the next nucleotide

nucleobase = one or two ring heterocyclic amine nucleoside = nucleobase + sugar nucleotide = nucleobase + sugar + some kind of phosphate = nucleoside + some kind of phosphate 1. Below are structures of ordinary nucleobases, nucleosides, and nucleotides. For each, state if it is based on purine or pyrimidine, then give the class (nucleobase, nucleoside, nucleotide) - e.g. purine nucleoside or pyrmidine nucleobase. (18 pts - 3 ea.)

You can tell that this is an image of a DNA nucleotide and not an RNA nucleotide because you see a O PO 0I double-stranded molecule, not a single-stranded molecule O uracil nitrogenous base, not a thymine nitrogenous base O O sugar with two, and not three, oxygen atoms thymine nitrogenous base, not a uracil nitrogenous base phosphate group, not a uracil O O Submit Request Answer
Question 7 What is the structure of DNA at the level above the nucleotide? Ladder-like double helix with sugar phosphate backbone forming the rungs of the “ladder” Single-stranded helical structure with sugar phosphate backbone connecting individual nucleotides Single-stranded helical structure with complementary base pairs connecting individual nucleotides Ladder-like double helix with complementary base pairs forming the rungs of the “ladder”
