2. DNA Replication and Protein Synthesis Pretest

3. The process represented in the graphic belowtakes place during • Diffusion • Mitosis • S phase • G1

4. Given the DNA strand 5’ AGTCAT 3’ which of the following would be produced during DNA replication • 3’ AGTCUT 5’ • 3’ TCAGTA 5’ • 3’ CGTACG 5’ • 3’ UCAGUA 5’

5. If the process of DNA replication is completed successfully the two DNA strands produced will be: • Opposites • Neighbors • Identical • Backward

6. What process is represented in the diagram to the right? • Replication • Transcription • Translation • Subscription

7. Messenger RNA (mRNA) is a product of which of the following processes? • Translations • Replication • Transcription • Mutation

8. Translation can be described as • Replicating a DNA sequence • The transfer of genetic instructions in DNA to mRNA. • The process in which the genetic code in mRNA is read to make a protein. • The process of making a protein in the nucleus.

9. All of the following are directly involved in translation except • mRNA • tRNA • DNA • Ribosomes

10. Which of the following is responsible for transport of amino acids to the ribosome during protein synthesis? • rRNA • DNA • mRNA • tRNA

11. Which of the following represents the process of Translation? a A. B. C. D.

12. Which of the following statements is correct?I. Translation always begins with an AUG start codonII. The start codon establishes the reading frame of mRNA.III. The mRNA molecule is read one codon at a time until stop codon is reached • I. only • II. only • II. and III. • I., II. , and III.

13. Using your amino acid chart, transcribe and translate the following DNA strand: ATA GGA AAG • Tyrosine, Leucine, Serine • Serine, Proline, Serine • Tyrosine, Proline, Phenylalanine • Serine, Leucine, Phenylalanine

14. Which of the following represents the correct order for the process of protein synthesis? • Transcription  translation  protein • Translation  replication  protein • Transcription  mitosis  translation • Protein  amino acid  mRNA

15. Put the following steps of transcription and translation in the correct order.1. mRNA travels from the nucleus to the cytoplasm2. DNA unwinds; mRNA nucleotides form mRNA3. Ribosomes bind to mRNA and “read” the message4. tRNAbrings amino acids to the ribosome • 2, 1, 3, 4 • 1, 2, 4, 3 • 2, 3, 4, 1 • 1, 3, 2, 4

16. The sentences below represent a gene. There are many different ways to alter a gene, just as there are many different ways that spelling errors can change a sentence. What type of DNA mutation does the belowmutated sentence represent? • Insertion • Deletion • Inversion • Translocation

17. A mutation has occurred in the mRNA codon CUU. Which of the following mutated codons would result in an amino acid different from that produced by the original CUU codon? • CUC • CUA • CUG • CAU
