Unit 1- Genetics

Question 1

Transformant

Answer 1

Cell that has taken up recipient DNA by transformation

Question 2

Competent

Answer 2

bacteria that can take up DNA naturally

Question 3

Homologous Recombination

Answer 3

Identical or similar regions of DNA align and exchange each other by excision-repair

Question 4

Transformasome

Answer 4

Compartment that has taken up double stranded SNA

Question 5

Transfection

Answer 5

Uptake of viral DNA

Question 6

Complementation

Answer 6

Mutated DNA expressed on a plasmid will correct the mutation

Question 7

Electroporation

Answer 7

Artificial transformation to induce foreign genes int o cells

Question 8

Bacteriophages

Answer 8

Bacterial viruses

Question 9

Transduction

Answer 9

Process of transferring DNA from one bacterium to another by phage

Question 10

Significance of lysogeny

Answer 10

Phage DNA often is integrated into the host cell DNA

Question 11

Virulence Factors

Answer 11

Phage DNA can alter host DNA and make bacteria more virulent or able to escape immune response

Question 12

Prime Factors

Answer 12

Extrachromosomal pieces of DNA

Question 13

Plasmids

Answer 13

Genes of unknown origin and often not necessary for growth

Question 14

F-factor

Answer 14

Fertility factor, genes promote replication and transfer of factor to recipient cells

Question 15

R-factor

Answer 15

F-factor and genes encoding resistance to specific antibiotics
