->Vocabulary building instructions
Instructions: For each section list the vocabulary words and make up a CQC sentence that uses each word and, at the same time, defines it. Underline the words being defined. (Glossary definitions will not receive full credit.)
Example:
Defining sentence: Gene: The gene is the fundamental unit of heredity. Genes make up chromosomes and are the blueprint for proteins that show, or express, physical traits. (ex: Certain genes direct the making of proteins that make up the color in your eyes.)
->Research Question Instructions Complete the following Data Tables, Exercises and Questions on a separate sheet of paper. Quality answers embody the question in the answer in a complete, informative sentence(s). Quality answers will receive the most credit. Use lined paper and ink or word processor.

Tell:
11. How RNA is different then DNA.
12. Which nitrogen base replaces Thymine in RNA.
Describe
13. Which of the two types of RNA is the "blueprint" for a new protein AND where this blueprint comes from.
14. Which type of RNA gathers amino acids in the cytoplasm and brings them back to the ribosome so a protein can be constructed a piece at a time.
15. Describe two ways that a gene or chromosome can be mutated.
16. Are most mutations good for an organism? Tell what usually happens to a mutated organism.

b. Questions: Answer questions 18-27 (50 total points!)
18. Mendel was an Austrian monk who performed some of the first ever experiments on genetics. Tell me how, when Mendel did his experiment before 1856 , that Mendel's work was still accepted by scientists in 1900, forty four years later??
19. Describe the process of how you get 1/2 of your chromosomes from your Mom and 1/2 of your genes from your Dad. (Check out Figs 4-11 and 5-1 to help you answer this clearly.
20. Explain, in science terms, why Mendel could cross tall purple flowered pea plants with short white flowered pea plants and get all tall purple flowered pea plants in the first generation.
21. Explain what probability is and give one example.
22. Why was it that Mendel was able to spot a predictable pattern in inheritance in peas?
23. Tell the difference between a Phenotype and a Genotype.
24. Certain genes code for a particular trait, like flower color, or tallness. Using an example, explain the difference in a trait that has homozygous alleles and one that has heterozygous alleles.
25. Explain the difference between an allele and a gene.
26. What is the difference between a dominant allele and a recessive allele?
Part E Assignment 5.2 Genetics Since Mendell (25 points for this job)
a. Complete Vocabulary building using the Science Words page 132 (3pts. Ea=10 pts.)
b. Questions: Answer question 28-30 (15 total points!)
28. Explain why you can mate a four o'clock plant with white flowers with one with red flowers and end up with pink flowers in the offspring
29. Tell what the scientific name is for the phenomena mentioned in 28 above.
30. Fingerprints are a prime example of many gene pairs acting together to produce a final product. What is the scientific name for this phenomena AND give another example of it.
Part F Assignment 5.3 Human Genetics (30 points for this job)
a. Complete Vocabulary building using the 3 Science Words page 137. (3pts. Ea. =10 pts.)
b. Questions: Answer questions 31-34. (20 total points!)

32. Explain what cystic fibrosis is AND tell what part of our population is most prone to this disease.
33. Tell what a sex linked disorder is AND give an example of one.
34. Genetic engineering is a very controversial subject nowadays. In fact, many countries in the European common market will not allow any of their food products to contain genetically engineered substances. Explain what it means to genetically engineer a plant and how it could positively affect the resulting crops.
Part G Assignment 5.4 The Human Genome Project (10) points for this job)
a. Complete Vocabulary building using the Science Word page 144. (3pts. Ea. = 5 pts.)
b. Questions: Answer question 35. (5 total points!)
35. Contrary to popular belief, the Human Genome project is not complete!!!! In fact, the project is still going on strong. What they did do so far is unravel the code for all the major genes in the genome of one human being. We don't know what traits each gene codes for yet and probably won't for a number of years. Completely explain how information from this project could be useful in the future.
