Question

3 true or false 5 points mutations are random. true false 4 multiple answer 10 points which of the following are frameshift mutations? select all that apply. silent mutation deletion mutation insertion mutation substitution mutation 5 multiple choice 10 points the model shows a mutation to a partial sequence of bases in a gene. which type of mutation does the model demonstrate? translocation insertion deletion substitution

Explanation:

• Question 3: Mutations are random events. They can occur spontaneously or be induced by environmental factors, and their occurrence is not directed towards a particular outcome.
• Question 4: Frameshift mutations shift the reading frame of the genetic code. Deletion (removing a nucleotide) and insertion (adding a nucleotide) mutations cause a frameshift. Silent mutations (no change in amino acid) and substitution mutations (replacing one nucleotide with another) do not cause a frameshift.
• Question 5: The model shows an addition of nucleotides (TATC is inserted), which is an insertion mutation. Translocation involves the movement of a segment of DNA to another location. Deletion is the removal of nucleotides. Substitution is the replacement of one nucleotide with another.

Answer:

• Question 3: True
• Question 4: deletion mutation, insertion mutation
• Question 5: insertion
