Complete each of the following statements by selecting from the bank of terms below. a. tRNA b. spontaneous c. repressible d. RNA processing e. mutagen f. SNRNA g. redundancy h. universal i. promoter j. elongation There are several three nucleotide codons that code for the same amino acid. This is known as (81). A specific three nucleotide codon for a fruit fly codes for the same amino acid as that same specific three nucleotide codon for a human. This means that the genetic code is (82). The three steps of transcription are initiation, (83), and termination. The (84) region on a chromosome is the sequence of nucleotides in DNA that indicates where the RNA polymerase complex should bind to initiate transcription. In a eukaryotic cell mRNA is modified in three ways. This is known as (85). The role of (86) is to combine with protein and then bind to introns to remove them and splice the RNA together. The role of (87) is to transport amino acids to the ribosome where the anticodon loop…
A nonsynonymous mutation is also referred to as missense mutation. Which of the following correctly describe these mutations? They are permanent and cannot revert or reverse mutate back into a wild-type sequence. They cause a non-functional amino acid to replace a functional amino acid. O They result in the insertion or deletion of a small number of nucleotides to the DNA. They change the nucleotide sequence of a gene but do not change the sequence of the resulting protein. None of the provided answers are correct. They convert a codon for a particular amino acid within a gene into a stop codon. They insert an additional amino acid into the final protein product.
A small section of a gene for a protein has the following nucleotide sequence: CTA TCC CCT ACG TCA Which of the following mutations would cause a silent mutation in the sequence shown above? a. Replacement of first thymine base with adenine base b. Replacement of second thymine base with guanine base c. Replacement of first cytosine base with guanine base d. Replacement of second adenine base with thymine base
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 nonsynonymous (missense) mutation that changes a single amino acid in the encoded protein? O 5-AUGCCCAGGGCC-3' O 5'-AUGCCCUGAGCU-3' O 5'-AUGCCCACAGCU-3 5'-AUGCCCCAGAGCU-3
As described earlier, DNA damage can cause deletion or insertion of base pairs. If a nucleotide base sequence of a coding region changes by any number of bases other than three base pairs, or multiples of 3, a frameshift mutation occurs. Depending on the location of the sequence change, such mutations can have serious effects. The following synthetic mRNA sequence codes for the beginning of a polypeptide: 5′-AUGUCUCCUACUGCUGACGAGGGAAGGAGGUGGCUUAUC-AUGUUU-3′ First, determine the amino acid sequence of the polypeptide. Then determine the types of mutation that have occurred in the following altered mRNA segments. What effect do these mutations have on the polypeptide products? a. 5′-AUGUCUCCUACUUGCUGACGAGGGAAGGAGGUGGCUUAUCA-UGUUU-3′ b. 5′-AUGUCUCCUACUGCUGACGAGGGAGGAGGUGGCUUAUCAU-GUUU-3′ c. 5′-AUGUCUCCUACUGCUGACGAGGGAAGGAGGUGGCCCUUAUC-AUGUUU-3′ d. 5′-AUGUCUCCUACUGCUGACGGAAGGAGGUGGCUUAUCAU-GUUU-3′
