Bio Sci 99 Problem Set #1 1. A viral DNA is analyzed and found to have the following base composition: G = 32%, A = 16%, C = 40%, T = 12%. a). What can you immediately conclude about this DNA? b). What kind of secondary structure do you think it would have? 2. Given the following sequence for one strand of a double-stranded oligonucleotide: 5’ ACCGTAAGGCTTTAG 3’ a). Write the sequence for the complementary strand. b). Write the sequence of the RNA complementary to the sequence given. 3. The following polynucleotide sequence is palindromic: TC AAGTCCATGGACTT GG AG TTCAGGTACCTGAA CC Show how this structure might form a cruciform conformation. 4. Which form of DNA is double-stranded RNA most like, A, B or Z? How long (in angstroms) would a double-stranded RNA molecule be if it was made up of 4,535 base pairs? See figure 8-19 for the rise per base pair. 5. You have isolated double-stranded DNA from two strains of bacteria. The T m for DNA sample A is 75 ° C and the T m for DNA sample B is 87
