Mutations Worksheet-Dcletlon, Inserilon & SubstitutionThere are several types of mutations:> DELETION (a base is lost/deleted)> INSERTION (an extra base is added/inserted)- Deletion\& insertion may cause what's called a FRAMESHIFT mutation, meaning the reading "frame"changes, thus changing the amino acid sequence from this point forward > SUBSTITUTION (one base is substituted for another)- If a substitution changes the amino acid, it's called a MISSENSE mutation- If a substitution does not change the amino add, it's called a SILENT mutation- If a...
3. (1.8 points) The normal CFTR gene contains these six codons near the middle of the transcript: AUU UCU VUA GCA AGA GCU... Al The corresponding amino acids in the normal CFTR protein are: (Use either the one-or three-letter amino acid codes A naint mutation changes the last nucleotide from U to C. At the DNA level, this is a transition transversion c) At the protein level, this is a (silent / missense / nonsense/frameshift ) mutation. D) Instead of...
Which of the following would result in the largest number of amino acids being changed? Select one: a. Silent mutation b. Missense mutation c. Frameshift d. Triplet repeat
11. Match each type of mutation with the corresponding description. (4 points) Missense An insertion or deletion of nucleotides that are not in multiples of 3. Nonsense A mutation that does not alter the protein sequence. Silent A mutation that confers an amino acid substitution. Frameshift A mutation that confers a premature stop codon.
Match each mutation with its appropriate description. A mutation that changes a codon that specifies an amino acid to a stop codon, resulting in premature termination of polypeptide synthesis. Silent mutation Frameshift mutation A mutation that results in a change in a codon such that a different amino acid is specified es Missense mutation A mutation that changes one codon to a different codon that specifies the same amino acid, such that there is no change in the resulting polypeptide....
The codon CAA codes for amino acid glutamine. Write the codon(s) obtained after a point mutation that resulted in Silent mutation Nonsense mutation Missense mutation Define a mutagen and give one example (other than radiation). Describe why UV is particularly damaging to nucleic acids. Is UV a form of ionizing or non-ionizing radiation?
A wild type gene contains the DNA 3'CCG5' which would code for the amino acid glycine. A mutation changed the DNA to 3'TCG5' which would code for the amino acid serine. This is an example of which of the following? Group of answer choices A silent mutation A missense mutation A nonsense mutation A frameshift mutation None of these
2. If a mutation occurs and alters the sequence CGATATGA to CGATATCA what will be the final effect - compared to the protein that was supposed to be made, how would the actual protein that is synthesized (made) look -shorter, longer or same? 3. Give the sequence of the protein that would result from such a mutation (mutation in question 4. What is the name given to such a mutation? Be specific (answer is not point mutation, deletion, insertion, substitution...
Please answer all.... Thank you!
81)If a polypeptide chain contains 600 amino acids, then the
gene coding for this polypeptide must contain _____.
600 nucleotides
1200 nucleotides
1800 nucleotides
1800 codons
1800 anticodons
More than one of the above are correct.
82) When we altered gene triplet in the DNA produces a chain-terminating codon in the mRNA, the (1pts) result is called a reverse mutation nonsense mutation missense mutation spontaneous mutation frameshift mutation 83) A single base substitution changes the...
