Chapter 6: Molecular Genetics Test Exam
Questions with Correct Answers
1. Amino Acid correct answers: Monomer
2. Restrictive enzymes make zig zag cuts in double-stranded DNA
leaving blunt ends correct answers: False
3. Restrictive Enzymes correct answers: Palindromic DNA sequences
4. Insertion Mutation correct answers: The addition of a base pair into a DNA sequence
5. Substitution Mutation correct answers: The replacement of a base pair in a DNA
sequence
6. If the recognition site for a single strand is correct answers: 5'
GAATTC 3' , then the comple- mentary strand is correct answers: 5'
CUUAAG 3'
7. If the recognition site for a single strand is correct answers: 5'
GTACTG 3' , then the comple- mentary strand is correct answers: 5'
CAUGAC 3'
8. If the recognition site for a single strand is correct answers: 5'
CCTATC 3' , then the comple- mentary strand is correct answers: 5'
GGAUAG 3'
9. Silent Mutation correct answers: A change in a single nucleotide within a gene that doesn't
change an amino acid
10. Missense Mutation correct answers: A change of the DNA sequence that changes a
single amino acid in the polypeptide
11. Mutations can be inheritable if they effect cells in the correct
answers: Testes
12. Nonsense Mutation correct answers: A change that produces a premature stop
codon
13. A DNA sequence will be cut using a particular restrictive enzyme.
The longer the recognition site of this enzyme, the more fragments you
would expect after digestion. correct answers: False
14. The paired bases of a DNA molecule are best described as
correct answers: Complementary
15. The nucleotide at the end of one strand of a fragment of
1/
9
, double-stranded DNA has a free phosphate attached to the 5' carbon
of its deoxyribose sugar. The complementary nucleotide has correct answers: A
hydroxyl group (-OH) attached to the 3' carbon of its deoxyri- bose sugar
16. The main support to the DNA molecule is provided by two
backbones which run along the two sides of the double helix. These
backbones consist of correct answers: Sugars and phosphates linked together
17. In DNA, phosphodiester bonds join correct answers: Phosphate groups
and sugars
18. A deoxyribose sugar molecule includes correct answers: 5 carbon
atoms
19. All the hydrogen bonds in DNA may be formed between
nitrogen and hydro- gen atoms, and oxygen and hydrogen atoms
correct answers: True
