Protien synthesis: Mutations

Question 1

Base substitution mutation

Answer 1

Is a form of mutation where a single nucleotide base is replaced or substituted with another.

Question 2

Same-sense

Answer 2

The substituted base does not cause a change in the amino acid sequence

Question 3

Missense

Answer 3

causes a change in the amino acid sequence, but does not cause a change in the shape or function of the protein.

Question 4

Nonsense

Answer 4

Substituted base results in the production of a stop codon, has a severe impact on the protein formed.

Question 5

Single base insertion

Answer 5

A form of DNA mutation where one base is added into the DNA chain, changing the genetic code dramatically.

Question 6

Single base deletion

Answer 6

A form of DNA mutation where one base is removed from the DNA chain, and lost forever.

Question 7

Reading frame-shift

Answer 7

a genetic mutation caused by a deletion or insertion of a base in a DNA sequence that shifts the way the sequence is read (in triplets).
