Question

Bacteria with the ability to break down certain types of plastic are placed with a colony of E. coli bacteria that lack this ability. Plasmid transfer occurs between the two colonies of bacteria and some of the E. coli gain the ability to break down plastic as well. What does this information demonstrate?
A.
Plasmids are proteins which build tissues.
B.
Plasmids are lipids which provide energy for the cell.
C.
Plasmids are nucleic acids which can pass on traits.
D.
Plasmids are carbohydrates which provide structural support

Answer 1

Answer: c

Explanation:

Because nucleic can pass on traits

Answer 2

The answer is; C

Plasmids are conferred through horizontal gene transfer in bacteria.  The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.
