Topic Four

Question 1

Mutation

Answer 1

Changes in the DNA sequence that may affect the resulting polypeptide

Question 2

Gene mutation

Answer 2

A Change is the order of a,t,c,g

Question 3

Point mutation

Answer 3

Caused by a substitution in one letter to another letter

Question 4

Silent mutation

Answer 4

DNA change results in an mRNA codon hat codes for the same amino acid

Question 5

Missence mutation

Answer 5

DNA change in results in an mRNA codon that codes for a different amino acid

Question 6

Nonsense mutation

Answer 6

DNA change results in an mRNA ‘“stop” codon

Question 7

Frameshift mutation

Answer 7

A mutation caused caused by an insertion or deletion of bases in the DNA sequence, thus causing a change in DNA triplets for the rest of the sequence, making different RNA condons, and the rest of the polypeptide I different .

Question 8

Insertion

Answer 8

Adding

Question 9

Deletion

Answer 9

Taking away

Question 10

Chromosomal mutation

Answer 10

Mutations that affect large chunks of a chromosome

Question 11

Duplication

Answer 11

When dna is taken out and doubled

Question 12

Inversion

Answer 12

When a large section is flipped

Question 13

Insertion

Answer 13

When a piece of dna is taken out and put somewhere else

Question 14

Translocation

Answer 14

Two chunks of dna switch locations

Question 15

Mutagens

Answer 15

Chemicals and radiation that cause dna mutation

Question 16
