What feature of mononucleotides provides the energy needed for polymerization when nucleic
acids are formed? - (ANSWER)their phosphate groups
Starting at the 5' end, what is the base sequence of the RNA strand shown in the figure? -
(ANSWER)UAGC
Pair up the nucleotide bases with their complementary partners. - (ANSWER)Adenine-Thymine:
5N, 2 rings, 3 H/ 2 N, 2 O, 1 ring, 4 H.
Guanine-Cytosine: 5N, 1 O, 2 rings, 4 H
3N, 1 O, 1 ring, 3H
Write the complementary sequence for the following DNA sequence, in order from 3' to 5':
