Bacterial Genome

Question 1

Genome

Answer 1

conserved core gene pool + a flexible gene pool

Question 2

Genome’s conserved core gene pool

Answer 2

generally concerned with basic cellular function/housekeeping genes (GC rich content)

Question 3

Genome’s flexible gene pool

Answer 3

encode for additional function that are not essential for bacterial growth but are advantageous, can be transferred via HGT

Question 4

Functional gene pool consists of

Answer 4

Genomic islands: mobile genetic elements >10kb
Genomic islets: mobile genetic elements <10kb
Prophages
Plasmids

Question 5

Genomic Island

Answer 5

large gene chunk that carries genes for adaptation, signs of mobile elements (phage or plasmid or tRNA), unstable, abnormal CG%, etc

Question 6

Answer 6

confers survival of organism under adverse conditions

Question 7

Pathogenicity Island

Answer 7

genomic island associated with pathogenesis

Question 8

Antibiotic Resistance Island

Answer 8

genomic island containing antibiotic resistant genes
