8. 10. 5 G T 3 3 T G T T 5 This segment of N has undergone a mutation in which three nucleotides have been deleted. repair enzyme would replace them with. GT.. G.. TG.. GT. 11. base sequence is shown below. GTG strand of mrn containing the repeating sequence GGGG could code for which of the following amino acid sequences?. lys arg glu lys. ser ser glu glu. lys arg lys arg. lys lys lys lys How would the base sequence be coded on mrn?. TGTG. GUGU. UGUG. UGU 9. Which of these would most likely cause a mutation?. the placement of ribosomes on the endoplasmic reticulum. the insertion of a nucleotide into N. the movement of transfer RN out of the nucleus. the release of messenger RN from N 12. Semi-conservative replication of N refers to the idea that. N molecules need to unwind before duplication begins.. each new N molecule contains two new single RN strands.. the two strands of N molecules run in opposite directions.. each half of the original N molecule is joined with a new complementary N strand. page 2 N and Protein Synthesis Practice
13. Genetic engineering has produced goats whose milk contains proteins that can be used as medicines. This effect was produced by 15. The diagram below shows the procedure scientists used to clone a frog from the nucleus of a skin cell.. mixing foreign genes into the milk.. injecting foreign genes into the goats udders.. inserting foreign genes into fertilized goat eggs.. genetically modifying the nutritional needs of the goats offspring. This procedure is evidence that.. the nuclei of the skin cells protect the frog. only skin cells can be used to clone a frog. the skin cells are the reproductive cells of the frog. the nuclei of skin cells contain all the N needed for a new frog 14. Mutations within a N sequence are. natural processes that produce genetic diversity.. natural processes that always affect the phenotype.. unnatural processes that always affect the phenotype.. unnatural processes that are harmful to genetic diversity. page 3 N and Protein Synthesis Practice
16. 18. substitution of thymine with adenine in one N codon causes a particular disorder. Which statement explains how the change in N leads to this disorder?. The deletion mutation prevents the production of the hemoglobin protein in the body. What is the relationship between the three structures in the diagram above?. N is produced by protein which is produced in the cell.. Protein is composed of N which is produced in the cell.. The frameshift mutation prevents the production of several proteins found in the blood.. The insertion mutation causes extra hemoglobin proteins to attach to red blood cells.. The point mutation causes a different amino acid to be added to the hemoglobin protein.. N controls the production of protein in the cell.. cell is composed only of N and protein. 17. Which statement about N is correct? 19. Genetic information usually flows in one specific direction. Which of the following best represents this flow?. child s N will be unrelated to the mother s or father s N.. child s N will show similarities to both the mother s and father s N.. female child s N will exactly match the mother s N.. N Protein RN. Protein RN N. RN Protein N. N RN Protein. male child s N will exactly match the father s N. page 4 N and Protein Synthesis Practice

What process does this diagram represent?. mutation. respiration. transcription. translation ccording to the data, which of these pairs of organisms are most closely related?. 1 and 2. 2 and 3. 2 and 4. 3 and 4 21. Look at the illustration below. 23. Which of these is not a use for N fingerprinting?. to determine how individuals are related This illustration is a model of. RN. N. a lipid. a protein. to make messenger RN. to determine a genetic sequence. to study inherited diseases page 5 N and Protein Synthesis Practice

Which of the following is correctly matched with its function?. rrn contains codes to make new ribosomes. N carries the amino acids to the ribosomes. trn combines with proteins to make up ribosomes. mrn carries genetic codes from nucleus to the ribosomes. 1. 2. 3. 4 page 6 N and Protein Synthesis Practice
29. The chromosome structure in a cell accounts for genetic variation based on the order of its 32. diagram of a cellular process is shown below.. sugar groups. nitrogen bases. hydrogen bonds. phosphate groups 30. One way RN is different from N is that RN contains. phosphate groups.. hydrogen bonds.. ribose.. bases. Which of the following identifies the process shown at point Z?. Translation. Translocation. Replication. Transcription 31. UUG Which of the following represents a trn complement to the codons above?. UGTG. TT. UGU. TT page 7 N and Protein Synthesis Practice
33. single nucleotide change results in the formation of a stop codon in the middle of a N sequence. Which of the following explains the effect on the protein produced from this gene? 34. The table below is a codon chart.. The protein would be shorter than expected.. The protein would be produced in smaller quantities.. The protein would be denatured easily by high temperatures..
