Question
1) Gene expression is the term used to describe the process that: a) Makes gene by using amino acid as a template via the process of transcription. b) Makes enzymes and other protein via the processes of polymerization and substitution. c) Makes enzymes and other proteins via the process of transcription and translation. d) Makes genes by using RNA as a template via the process of translation.
2) Why would the use of a drug that inhibits nuclear mRNA export affect the production of protein in animals but not in bacteria? a) The mechanism for translation in bacteria is much different than that in animal cells. b) Bacteria lack nuclei, so this treatment would be pointless in bacteria. c) Bacteria are better able to metabolize drugs than animals. d) Animal cells modify their RNA prior to nuclear export, while bacteria do not.
3) Which of the following is a False statement regarding the genetic code? a) It is comprised of three nucleotide sequences. b) It is a redundant as more than one codon can code for on amino acid. c) The start codon is AUG d) Sometimes one codon codes for two amino acids. e) It dictates the amino acid sequence in a protein.
