Genetic exam test queries and answers graded A+



1. A DNA sequence is 5'-TGC GCC GAT GGA GCC
Cysteine - Alanine -
CAT
GGT-3'. What is the sequence of amino acids Aspar- tic acid - Glycine
encoded by this gene? - Alanine
- Histidine - Glycine




2. A DNA sequence is represented by the
sequence of nucleotides as 5'-TGC GCC GAT
GGA GCC CAT GG-3'. A frameshift occurs
from addition of a single nu-
cleotide, shown by the blue letter A (meaning
addition of an adenine nucleotide), resulting in
the following se- quence:5'-TGC AGC CGA TGG
AGC CCA TGG T-3'. What is
the sequence of amino acids encoded by this
mutated gene?
Cysteine - Alanine -
3. A DNA sequence is 5'-TGC GCC GAT GGA GCC Aspar-
CAT
GGT-3'. A point mutation arises and changes the G(10) tic acid
nucleotide to T(10). The resulting sequence will be:
5'-TGC GCC GAT TGA GCC CAT GGT-3'. What will be the
resulting sequence of amino acid:



4. A change in the first nucleotide of TGG .
from T to G will result in a
mutation from
to
