C
Plasmid
D
Ribosome
Verified step by step guidance
1
Understand the concept of a vector in genetic engineering: A vector is a vehicle used to transfer genetic material into a cell. It is crucial in processes like cloning, gene therapy, and the production of genetically modified organisms.
Identify the characteristics of a plasmid: Plasmids are small, circular DNA molecules found in bacteria that can replicate independently of chromosomal DNA. They are commonly used as vectors because they can carry foreign genes and introduce them into host cells.
Differentiate between the options provided: Mitochondria, lysosomes, and ribosomes are cellular organelles with specific functions. Mitochondria are involved in energy production, lysosomes in digestion and waste processing, and ribosomes in protein synthesis. None of these are typically used as vectors for gene transfer.
Recognize why plasmids are suitable vectors: Plasmids can be easily manipulated in the laboratory to include new genes. They can be introduced into bacterial cells through a process called transformation, where the bacteria take up the plasmid DNA from their environment.
Conclude that plasmids are the correct answer: Given their ability to carry and introduce new genetic material into cells, plasmids are the most suitable option among the choices provided for acting as vectors in genetic engineering.
