Question

translate-Bing "Waiting for response fix- 3 attempts left Check my Report problem Hint Solution Enter your answer in the provided box Bacteria often have two sources of gemetic material: the bacterial chromovomal DNA, and the plasnid DNA. Chromosomal DNA is the single largest source of genetic information. and is usually a few million nucleotides in length. Plasmids are much smaller, rangimng in sie from about 3,000 to 500,00 nucleotides in length, but any plasmid may be found in multiple copies because each has its own origin of replication and can therefore be replicated independently of other plasmids and the chromosomal DNA. Given the data below please calculate the percentage of genetic material in a bacterial cell that comes from plasmid DNA droalOuided Solution Genetic material Leagth (in kilobases)" Copy number Plasmid I Plasmid2 Plasmid 3 Plasmid 4 1103 kb 267 kb 434 kb 447 kb 313 kb 57 25 1 kilobase- 1000 nuckotides

Explanation / Answer

Total size

Chromosomal DNA =1103000 bp

Plasmid 1=15219

Plasmid 2=10850

Plasmid3= 38442

Plasmid 4= 20658

Total =1172950 bp

Plasmid size= 85169

Persentage of plasmid size is = 7.26%
