D1.3 - Mutations & Gene Editing

Question 1

genetic mutations

Answer 1

structural changes in genes at molecular level

Question 2

types of genetic mutations

Answer 2

substitution
insertion
deletion

Question 3

same sense mutation

Answer 3

change in bases does not change amino acid

Question 4

nonsense mutation

Answer 4

change causes stop codon to replace amino acid

Question 5

mis-sense mutation

Answer 5

change causes different amino acid to be inserted

Question 6

SNP full name

Answer 6

single nucleotide polymorphism

Question 7

what is SNP

Answer 7

areas where genetic codes differe due to accumulation of base changes

Question 8

consequences of insertion & deletion

Answer 8

change in reading frame

Question 9

causes of gene mutation

Answer 9

errors in replication
mutagens (chemicals & radiation)

Question 10

somatic cell

Answer 10

body cell

Question 11

consequences of muations on somatic cells

Answer 11

not passed to offspring

Question 12

germ cell

Answer 12

gamete producing cell

Question 13

consequences of mutations on germ cells

Answer 13

can be passed to offspring, best to minimize exposure to mutagens

Question 14

alleles

Answer 14

different versions of a gene

Question 15

influence of alleles on genetics

Answer 15

increase genetic variety
