What is a mutation?
Answer
  • a physical problem
  • a change in the DNA sequence
  • something that has affected your appearance

Question 2

Question
what is the name of something that causes mutations?
Answer
  • mutagens
  • UV light
  • chemicals

Question 3

Question
when can't the mutations be inherited by the offspring?
Answer
  • occurs in the body cells - somatic mutation
  • occurs in the sex cells - gametic mutation

Question 4

Question
what are the main types of mutations?
Answer
  • substitution
  • nonsense
  • insertion
  • deletion
  • mutagens
  • chromosomal

Question 5

Question
what are the types of substitution mutation?
Answer
  • nonsense
  • insertion
  • silent
  • missense
  • deletion

Question 6

Question
what types of mutations causes frameshift?
Answer
  • substitution
  • insertion
  • deletion

Question 7

Question
frameshift is when a base is inserted or deleted and causes the bases/triplets move along one. resulting in codons shifting so the amino acids are coded differently and overall the protein may not carry out the correct cellular function.
Answer
  • True
  • False

Question 8

Question
what is nonsense?
Answer
  • codes for a different amino acid
  • codes for a stop codon
  • the same amino acid, because of redundancy due to degeneracy

Question 9

Question
what is a silent mutation?
Answer
  • code for a stop codon
  • the same amino acid, because of redundancy due to degeneracy
  • code for a different amino acid

Question 10

Question
what is missense?
Answer
  • the same amino acid, because of redundancy due to degeneracy
  • codes for a stop codon
  • codes for a different amino acid

Question 11

Question
mutations can be only harmful
Answer
  • True
  • False
