What kind of mutation occurred?
DNA sequences can often be used to determine relationships between...
nutritional needs
organisms
habitats
Which type of mutation is MOST LIKELY to cause the greatest disruption?
Frameshift
Silent
Point
A mutation in the third base of a codon for the amino acid Proline (Pro) will always be a silent mutation. Which of the following pieces of information best supports this claim?
Proline is always made from the same 3 bases
As long as the first two bases on the mRNA codon are both C, it will always code for proline; regardless of the 3rd base
Proline is a stop codon, so it isn't actually an amino acid and therefore cannot be mutated
Proline has evolved to become resistant to harmful mutations
How many nucleotides are involved in a point mutation?
1
2
3
4
The image shown depicts a point mutation. Which of the following categories best describes this mutation?
Missense
Nonsense
Silent
Neutral
Layla is typing on an old typewriter. As she looks at her work, she realizes that the "v" key is not working. Therefore, when she tries to type the word "favorable," she actually types "faorable." This example is an analogy to which of the following types of mutations?
Deletion
Insertion
Substitution
Duplication
Which of the following types of mutations will impact the FEWEST codons?
Substitution
Insertion
Deletion
Frameshift
If a mutation codes for "stop" in the amino acid chain, this is called a:
nonsense mutation
missense mutation
silent mutation
frameshift mutation
If UCU is changed to UCC, this is a _______________________________.
