DNA is the structure which is made up of multiple nucleotides(a nitrogenous base, sugar and a Phosphate group) which are connected by hydrogen bonds.
The nitrogen bases are Adenine, Guanine, Cytosine, Thymine and Uracil is seen in RNA instead of Thymine.
The sugar are two: Deoxyribose sugar in case of DNA and Ribose sugar in case of RNA.
The Phosphate groups are connected to the sugar molecules.
The above structure is DNA consisting of one Purine (Adenine) and one Pyrimidine (Thymine), two Deoxyribose sugars connected to them and Phosphate groups are connected to sugar molecules.
a. So, the above structure can be confirmed as DNA as it is having Deoxyribose sugars and Thymine nitrogen base.
b. The two bases shown above are 1. Adenine 2. Thymine.
c. Below is the complementary strand and hydrogen bonding and sugar Phosphate backbone is shown.

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
Each of the following statements about the structure of DNA may be either true or false. Choose the appropriate answer for each of these statements. Bonding between adenine and thymine on opposite strands involves two hydrogen bonds. Nitrogenous bases are located on the outside of the double helix: phosphates are located towards the middle of the double helix. Bonding between guanine and cytosine on opposite strands involves three hydrogen bonds. DNA and RNA are structurally different due to the difference...
2. The sequence below represents two DNA strands linked together by hydrogen bonds. The smaller DNA strand has a 3'-OH that will be used by the DNA polymerase to add nucleotides using the longer DNA strand as a template. You add dATP, SCTP, dTTP, and ddGTP (dideoxy-GTP); and incubate at the DNA polymerase optimum temperature to allow the extension of the smaller DNA strand. Using the symbols below, draw the extended DNA strand (you don't need to draw the template...
Draw the chemical structure of the DNA trimer 5’-ACG-3’ hydrogen-bonded to its complementary strand. Include the deoxyribose rings and the phosphodiester backbones and show the H-bonding interactions between the bases.
You are told that in the DNA sequence below the bottom strand is the coding strand. 5' - CCTAAGGGTTAA - 3' 3' - GGATTCCCAATT - 5' If this sequence were to be transcribed, what would the sequence of the messenger RNA be? 5' - UUAACCCUUAGG - 3' This is the answer, can someone explain how you get this answer.
1. DNA Replication (10 Pts.) Create your own strand of dsDNA being sure to indicate 3’ and 5’ ends. Tell me how DNA is replicated including how bases pair. Show me DNA replication using your strand (this can be hand drawn). What enzymes are used to actually make the new DNA? How is the DNA primed for replication? What enzyme is responsible for this? What enzyme removes the primer and fills in the gap with DNA? What enzyme covalently bonds...
