Question

Which of the following statements best explains the structure and importance of plasmids to prokaryotes?
Plasmids are circular, single-stranded RNA molecules that transfer Information from the prokaryotic chromosome to the ribosomes during protein synthesis.
B
Plasmids are circular, double-stranded DNA molecules that provide genes that may aid in survival of the prokaryotic cell.
с
Plasmids are single-stranded DNA molecules, which are replicated from the prokaryotic chromosome, that prevent viral reproduction within the prokaryotic cell.
D
Plasmids are double-stranded RNA molecules that are transmitted by conjugation that enable other prokaryotic cells
acquire useful genes.

Answer 1

Answer:

B  Plasmids are circular, double-stranded DNA molecules that provide genes that may aid in survival of the prokaryotic cell.

Explanation:

Plasmids would be additional chromosomal, double stranded also it is covalently that are closed and circular DNA molecules. It possesses genes that represent some unique attributes to the prokaryotic cell like fertility factor, F plasmid, etc. It may existed as an independent entity that should be within the cell or may be they integrate within the host genome this we called as an episomal in nature

In addition to this, Plasmids plays a significant role in the gene transfer i.e. horizontal that should be within the prokaryotes and are widely used in the recombinant DNA technology like vectors

Therefore, the option b is correct

Answer 2

Plasmids are the extrachromosomal material present in prokaryotic cells that divides independently. They are circular and aids in the survival of prokaryotic organisms.

What are plasmids?

Plasmids are the extra genetic material that is double-stranded and circular found along with the nucleoid in the cytoplasm of the prokaryotic cell. They are majorly used in the genetic engineering process.

They provide protection and antibiotic resistance in the prokaryotes like bacteria as they carry antibiotic degrading genes and enzymes. They are capable of producing enzymes that can degrade antibiotics by cleaving them.

Therefore, option B. plasmids are double-stranded molecules that confer protection to prokaryotic cells.
