- Describe how the sequence of nucleotides in mRNA codes for the amino acids of a protein. How can the insertion or deletion of even one nucleotide in mRNA cause significant changes to the protein that results?arrow_forwardWhich of the following describe how the order of nucleotide bases along a gene in the DNA ultimately determines the primary structure of a protein and how the primary structure ultimately determines the three-dimensional shape and function of the protein coded for by that gene. A Certain amino acids in a protein interact with other amino acids in that same protein and so the order of amino acids ultimately determines the 3-dimensional tertiary structure of that protein. B The order of nucleotide bases along the DNA is transcribed into complementary tRNA which is translated into the correct amino acid sequence for the protein by mRNA. C The order of nucleotide bases along a gene determines the order of amino acids in the resulting protein. The order of amino acids in the protein is called its secondary structure.arrow_forwardGeneticists have found that when they cut out a eukaryotic gene from genomic DNA that they can hybridize one of the strands of that gene to the mRNA for that gene by allowing the strands to hydrogen bond. Why is it sometimes claimed that alternative splicing of exons from a single gene results in a set of proteins of related function?arrow_forward
- For 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_forwardBriefly describe the function of the following in protein synthesis. a. rRNA b. tRNA c. mRNAarrow_forwardIf the coding region of a gene (the exons) contains 2,100 base pairs of DNA, would a missense mutation cause a protein to be shorter, longer, or the same length as the normal 700 amino acid proteins? What would be the effect of a nonsense mutation? A sense mutation?arrow_forward
- A certain mRNA strand has the following nucleotide sequence: 5AUGACGUAUAACUUU3 What is the anticodon for each codon? What is the amino acid sequence of the polypeptide? (Use Figure 13-5 to help answer this question.) Figure 13-5 The genetic code The genetic code specifies all possible combinations of the three bases that compose codons in mRNA. Of the 64 possible codons, 61 specify amino acids (see Figure 3-17 for an explanation of abbreviations). The codon AUG specifies the amino acid methionine and also signals the ribosome to initiate translation (start). Three codonsUAA, UGA, and UAGdo not specify amino acids; they terminate polypeptide synthesis (stop).arrow_forwardWhat happens when one base pair of DNA is lost from the coding region of a gene because of mutation? First explain how this would affect the mRNA sequence, and second, explain how this would alter the amino acid of the protein that is encoded.arrow_forwardDiscuss the following statement: “from the nucleotide sequence of a cDNA clone, the complete amino acid sequence of a protein can be deduced by applying the genetic code. thus, protein biochemistry has become superfluous because there is nothing more that can be learned by studying the protein.”arrow_forward
- What might be the result of a mutation of DNA in which a triplet code such as UAC now says UAA in the middle of a protein? Could this cause problems? Might we see these problems in nature? Speculate as to an example.arrow_forwardEach of the following statements about protein synthesis is false.Correct each to make a true statement. a. In a gene, each nucleotide specifies one amino acid in a protein sequence. b. A transcription factor must bind to the promoter region of a gene before the enzyme DNA synthetase is able to bind and begin transcription. c. The enzyme RNA polymerase builds a strand of transfer RNA, whose codons are complementary to DNA’s triplets. d. Proteins destined for secretion from the cell enter the nucleus after translation, to be folded and modified. e. During translation, amino acids are delivered by the messenger RNA transcriparrow_forwardIn relation to central dogma of molecular biology answer the following questions: The length of a particular gene in human DNA, measured from the start site for transcription to the end of the protein-coding region, is 10,000 nucleotides, whereas the length of the mRNA produced from this gene is 4000 nucleotides. What is the most likely reason for this difference?arrow_forward
