polynucleotide strand has the bases G, T, C, and T, starting from the 5’ end. Assuming this is a DNA polynucleotide, draw the given DNA strand and its complementary strand at the molecular level showing the hydrogen bonds. Draw arrows showing the 5’ to 3’ direction of each strand. Use the arrows to make sure the second strand is antiparallel to the first.

Write out the DNA sequence using the following instructions: This is a double stranded DNA hydrogen bonding with each other following the principle of complementary base-pairing Each strand contains ten nucleotides Each strand contains all four different types of nucleotides You should indicate clearly the directionality of each strand in your answer You do not need to draw the full nucleotide structure. Use the one-letter code (A, T, G, C, or U) to represent each nucleotide
Draw a stylized diagram of double-stranded DNA. Use a pentagon for sugar, a circle for phosphate and a square for bases. Label each base A, T, C or G. Show two pairs of nucleotides connected via hydrogen bonds (use all 4 letters). Show the polarity of each strand and clearly indicate the number of hydrogen bonds in each pair of nucleotides. Draw a solid-line circle around a nucleotide. Draw a dashed-line circle around a nucleoside. Indicate a phosphodiester bond using an arrow.
The DNA sequence you use will be the following: T - A - G - C - C - A. You will need to make the complementary strand - fill in the table below with the complementary base pairs (remember Chargaff’s rule: A = T and C = G) 5’ T A G C C A 3’ 3’ 5’
draw a strand of DNA 4 nucleotides long (4 nucleotides on each side). Label the 5’ ends, the 3’ ends, the bond that holds the DNA backbone together, the glycosyl bond, and the bond that holds the nitrogenous bases together. You can use “P” to represent phosphate, and ATCG to represent the nitrogenous bases. Please try to draw the sugar accurately and include any unbonded functional groups, including the oxygen within the molecule.

DNA molecules are anti-parallel strands running 5’ to 3’ or 3’ to 5’. What do 5’ and 3’ correspond to? Be specific
DNA structure depends on base pairing of its four nucleotides, A, C, T, and G. Nucleotide A pairs with T, and nucleotide C pairs with G. This forms a four-letter DNA “alphabet." Because DNA codes for amino acids in sets of three nucleotides, there are 4 cubed (4'), or 64, possible combinations, coding for 20 different amino acids. What is the best explanation for why there is no selective advantage for DNA to have five nucleotides (e.g., A, C, T, G, and E) with C pairing with either G or functionally equivalent E? It would be impossible to form the DNA molecule, because it must have an equal number of Cs and Gs. Because G and E have the same role, there would still be four functional letters of the alphabet. Replication would be inaccurate because sometimes C would bond with G and sometimes C would bond with E. There would be a five-letter alphabet with 125 combinations, which is too numerous. It is impossible because there are not five known nucleotides in the cell.
draw a picture of a SINGLE strand of DNA (a polynucleotide) composed of 9 (nine) nucleotides of your choice. Do use ALL 4 nucleotides. Use 3 simple symbols to represent the phosphate, the sugar, and the base in each nucleotide. For example, use a circle with the letter “P” for the phosphate in the backbone, a square with the letter “S” for the sugar in the backbone, and a triangle with the letter “A, T, C or G” for the bases.As you draw the diagram be sure to put solid lines for the covalent bonds you are creating to join new nucleotides to the elongating DNA chain.
