Question

1. Match the following:

a. exon shuffling

b. point mutation

c. horizontal transfer

allows bacteria to become antibiotic resistant

can only occur in eukaryotes

often has a neutral effect

involves errors in replication of chromosome ends

2. Match the term with the best description

a. exon shuffling

b. gene duplication

c. horizontal transfer

d. mutation in gene

e. mutation in regulatory region

due to unequal crossing over between homologous genes

due to unequal crossing over between unhomologous genes

can involve plasmids

can alter the expression of a protein

can alter the structure of a protein

due to errors in transcription and translation

1. a) exon shuffling: can only occcur in eukaryotes

b) point mutation: involves errors in replication of chromosome ends

c) horizontal transfer: allows bacteria to become antibiotic resistant

2. a) exon shuffling: due to unequal crossover between unhomologous genes

b) gene duplication: due to unequal crossing over between homologous genes

c) horizontal transfer: can involve plamsids

d) mutation in gene: can alter the structure of a protein

e) mutation in regulatory region: can alter the expression of a protein
