Vedclass · Answer

(B) In a bacterial cell,the copy number of $DNA$ molecules varies significantly based on the type of vector or genetic element.$1$. Genomic $DNA$: Usually,there is only $1$ copy of the bacterial chromosome per cell.$2$. Plasmid: Plasmids are extrachromosomal $DNA$ molecules that can have a copy number ranging from $1$ to $100$ per cell.$3$. Bacteriophage: Bacteriophages (like $\lambda$ phage or $M13$ phage) can replicate to produce a very high number of copies (often $10$ to $100$ or more) within the host cell during the lytic cycle.Therefore,the order of copy number capacity is: Bacteriophage > Plasmid > Genomic $DNA$.

Choose the correct option based on the copy number capacity in a bacterial cell.
