Which of the following can serve as a vector to carry a gene from one organism into a bacterial cell?
A
Ribosome
B
Lysosome
C
Mitochondrion
D
Plasmid
Verified step by step guidance1
Understand the concept of a vector in genetic engineering: a vector is a DNA molecule used as a vehicle to transfer foreign genetic material into another cell.
Identify the characteristics required for a good vector: it should be able to replicate independently within the host cell and carry the gene of interest.
Evaluate the options given: ribosome, lysosome, mitochondrion, and plasmid, considering their functions and structures.
Recall that ribosomes are involved in protein synthesis, lysosomes in digestion, and mitochondria in energy production, none of which are suitable for carrying foreign DNA.
Recognize that plasmids are small, circular DNA molecules found in bacteria that can replicate independently and are commonly used as vectors to transfer genes into bacterial cells.
