- 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 nucleotideGiven the following sequence for one strand of a double-strand oligonucleotide: 5’ACCGTAAGGCTTTAG3’ a. Write the sequence for the complementary DNA strand. b. Write the sequence of the RNA complementary to the strand showndraw 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.
