  • UV light
  • chemicals

Questão 3

  • occurs in the sex cells - gametic mutation

Questão 4

Questão

  • substitution
  • nonsense

  • deletion
  • mutagens
  • chromosomal

Questão 5

Questão
what are the types of substitution mutation?
Responda
  • nonsense
  • insertion
  • silent
  • missense
  • deletion

Questão 6

Questão
what types of mutations causes frameshift?
Responda
  • substitution
  • insertion
  • deletion

Questão 7

Questão
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.
Responda
  • True
  • False

Questão 8

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

Questão 9

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

Questão 10

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

Questão 11

Questão
mutations can be only harmful
Responda
  • True
  • False
