D1.3 Mutations and Gene Editing

Question 1

Same-sense mutations

Answer 1

Change in codon resulting in the same amino acid (neutral)

Question 2

Non-sense mutations

Answer 2

Change in codon resulting in a stop codon

Question 3

Mis-sense mutation

Answer 3

Change in codon resulting in a different amino acid

Question 4

Single nucleotide polymorphisms (SNP)

Answer 4

Inheritance results in the spread of a mutation; resulting in 1% of the population having it.

Question 5

CRISPR-cas9

Answer 5

Enables the modification of genes via Cas9 cutting the DNA at the target location

Question 6

Non-disjunction

Answer 6

failure of the chromosomes to separate during anaphase
