Explanation

Question 2 of 11

1

what is the name of something that causes mutations?

Select one of the following:

  • mutagens

  • UV light

  • chemicals

Explanation

Question 3 of 11

1

when can't the mutations be inherited by the offspring?

Select one of the following:

  • occurs in the body cells - somatic mutation

  • occurs in the sex cells - gametic mutation

Explanation

Question 4 of 11

1

what are the main types of mutations?

Select one or more of the following:

  • substitution

  • nonsense

  • insertion

  • deletion

  • mutagens

  • chromosomal

Explanation

Question 5 of 11

1

what are the types of substitution mutation?

Select one or more of the following:

  • nonsense

  • insertion

  • silent

  • missense

  • deletion

Explanation

Question 6 of 11

1

what types of mutations causes frameshift?

Select one or more of the following:

  • substitution

  • insertion

  • deletion

Explanation

Question 7 of 11

1

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.

Select one of the following:

  • True
  • False

Explanation

Question 8 of 11

1

what is nonsense?

Select one of the following:

  • codes for a different amino acid

  • codes for a stop codon

  • the same amino acid, because of redundancy due to degeneracy

Explanation

Question 9 of 11

1

what is a silent mutation?

Select one of the following:

  • code for a stop codon

  • the same amino acid, because of redundancy due to degeneracy

  • code for a different amino acid

Explanation

Question 10 of 11

1

what is missense?

Select one of the following:

  • the same amino acid, because of redundancy due to degeneracy

  • codes for a stop codon

  • codes for a different amino acid

Explanation

Question 11 of 11
