Solutions to Problems
28.1




28.2




28.3 DNA (5' end) GGCTAATCCGT (3' end) is complementary .to DNA (3' end)
CCGATTAGGCA (5' end).
Remember that the complementary strand has the 3' end on the left and the 5' end on the
right.
The complementary sequence can also be written as:
DNA (5' end) ACGGATTAGCC (3' end). Be sure that you know which format is being
used (3' to 5', or 5' to 3').

28.4




28.5 DNA (5' end) GATTACCGTA (3' end) is complementary to
RNA (3' end) CUAAUGGCAU (5' end)

28.6 RNA (5' end) UUCGCAGAGU (3' end)
DNA (3' end) AAGCGTCTCA (5' end) antisense (noncoding) strand

28.7–28.8
Several different codons can code for the same amino acid (Table 28.1). The
corresponding anticodon follows the slash mark after each codon. The mRNA
codons are written with the 5' end on the left and the 3' end on the right, and the
tRNA anticodons have the 3' end on the left and the 5' end on the right.

Amino acid: Ala Phe Leu Tyr
