- You may wish to consult the genetic code above to answer the following question. A mutation has changed a portion of a protein coding gene that encodes a messenger RNA sequence. The original messenger RNA sequence is 5'-AUGCCCAGAGCU-3' Which mutation is a frameshift mutation that changes all of the amino acids that follow the changed sequence? O 5-AUGCCCUGAGCU-3' 05-AUGCCCCAGAGCU-3" 05-AUGCCCACAGCU-3" 05 AUGCCCAGGGCC-3"arrow_forwardMatch each statement below with the correct RNA molecule. A. rRNA B. mRNA C. tRNA D. uRNA 1. Contains the codon 2. is read by the ribosome 3. contains the anticodon 4. Transport amino acids to the ribosomearrow_forwardA few genes produce regulatory molecules that help the cell assemble proteins. The journey from gene to protein is complex and tightly controlled within each cell. Which of the following statements best describes the role of DNA and RNA in protein synthesis? * A. DNA is the primary genetic material contained within a cell. B. DNA is the long-term storage while RNA is the messenger containing instruction from DNA C. DNA creates protein during protein synthesis & converts it into usable molecules while RNA assembles amino acid into a protein. D. All of the above. Humans and chimpanzees share many common characteristics. How would you explain the similarities of the amino acid sequences that can be found in both organisms? * A.

- The information in DNA is used by cells to produce proteins that perform various functions in cells. The process of gene expression involves the transcription of a mRNA molecule that is translated by ribosomes into a strand of amino acids.1. Use your DNA strand to construct a part of a messenger RNA molecule.DNA: A G T A C C G G G C A A A C T G C A T T G T GmRNA:2. find it by searching the internet for the "Genetic Code Chart" to determine the sequence of amino acids in your polypeptide chain. Remember to START translation at the start codon by adding a Methionine and STOP translating when you reach a stop codon.arrow_forwardFor each of the following, identify the type of RNA involved (mRNA, rRNA, or tRNA). a. Transports the correct amino acid to the ribosome, using the information encoded in the mRNA. b. Is a major component of ribosomes. c. Specifies the order of amino acids in a protein, using a series of three-base codons, where different amino acids are specified by particular codons. d. Contains a three-base anticodon that pairs with a complementary codon revealed in the mRNA. e. Assists in making the bonds that link amino acids together to make a protein.arrow_forwardMatch the following with the correct nucleic acid. (mRNA, tRNA, rRNA, or All RNA) 1. This molecule is complementary to DNA. 2. This molecule is part of translation. 3. This molecule is part of the ribosome. 4. This molecule contains anticodons. 5. This molecule is esponsible for bringing amino acids to the ribosome. 6. DNA is used as a template to create this type of RNA molecule. 7. This molecule is part of transcription. 8.
