2. Circle the correct suspect
This technique is done through Gel Electrophoresis and
this is known as DNA Fingerprinting
3. Put the events of genetic expression in the correct
order. (Protein-RNA-DNA-Amino Acid-Genetic Expression)
DNA-RNA-Amino Acid-Protein-Genetic Expression
4. When there is a mutation in the gamete of an organism, where will it be most likely
transferred to? Offspring
5. What is selective breeding and give an example. Selective breeding: directed breeding to
produce plant and animal with desirable traits. Ex: breeding plants to produce larger fruits/vegetable
6. If a gene that expresses a color is inserted into the DNA of another organism, how can a
scientist determine if the gene is transcribed and translated? It will express the trait (show the
color)
1
7.
a. What process is shown in X? DNA Replication
b. What process is shown in Y? Transcription
c. What process is shown in Z? Translation
8. How does DNA in cells determine an organisms complex traits? DNA contains codes for
proteins, which are necessary for the growth and functioning of an organism
Word Bank:
Anti-Codon
rRNA
mRNA
tRNA
Nucleus
Answer the following question using the diagram above
9. What does E represent? Anti-Codon
10. What does A represent? Nucleus
11. What does D represent? tRNA
12. What does C represent? rRNA
13. What does B represent? mRNA
14. What does the technique of Chromosome painting allow for in different species? To
compare the genomes of different species
15. Why is the sequence of bases in DNA important? It provides the instructions for the
trait(s) of an organism
16. Put the following events of mutations in the correct order
3. Appearance of characteristic
1. A change in the sequence of DNA bases
2. Joining amino acids in sequence
2
17. What type of molecule is being produced from the DNA strand above? Messenger RNA
18. True or False A mutation is least likely to affect a cell when the mutation produces a triplet
that codes for the same amino acid as that original triplet. True
Matching; Match the correct mutation with the correct diagram
19. B Duplication Mutation
20. C Inversion Mutation
21. D Translocation Mutation
22. A Deletion Mutation
A
B
C
D
23. DNA segment is changed from TTGCCA to TTGGCCA. This is a Insertion mutation
24. DNA segment is changed from TTGCCA to TAGCCA. This is a Substitution mutation
25. What causes a frameshift mutation? A Deletion or Insertion of a base, which cause the
DNA sequence to sift.
26. What type of biomolecule molecule will turn yellow to dark purple in the present of Lugol’s
iodine? Polysaccharide (Starch)
27. Birds can exhibit symbiotic relationships between the different species. For instance, a
cuckoo bird may lay its eggs in the nest of a nearby warbler bird. The cuckoo’s young will then
be raised by the warbler, as the warbler’s young have been displaced. The symbiotic
interaction this describes is Parasitism
3
28. What location of the cell does the synthesis of new proteins occur? In the ribosomes that
are bound to the endoplasmic reticulum
29. When chromosomes crossover during meiosis what will increase in the offspring? Genetic
Variation
30. Circle which organism that would have the greatest biomass in an ecosystem.
Bird
Frog
Water
Rock
Pond grass
Fly
31. Describing the process of cloning. The nucleus is removed from a body cell in one organism and is
placed in an egg cell that has had its nucleus removed. This results in the production of an organism
that is genetically alike.
32. Which will most likely cause a variation to occur within a species? Mutation
33. Label each diagram as the process of mitosis or meiosis
Mitosis
Meiosis
4
34. The graph below show the basic changes in a forest community after a disturbance occurred. What
suggest the changes was cause by? Succession after a fire
Matching: Match the correct mutation with the definition
35. AB Mutation that results from a change in a single nucleotide.
36. D Mutation from the deletion of a single nucleotide.
37. BC Mutation from the insertion of single nucleotide.
38. A Mutation where the amino acid does not change.
39. B Mutation when one amino acid is changed.
40. C Mutation when there is a premature stop signal.
A. Silent mutation (point mutation)
B. Missense mutation (point mutation)
C. Nonsense mutation (point mutation)
D. Deletion mutation (frameshift mutation)
AB. Substitution mutation (point mutation)
BC. Insertion mutation (frameshift mutation)
