Which of the Following is Not True of Vectors

Question

Which of the following is not true of vectors?
A) They are easy to manipulate.
B) They contain a gene for drug resistance.
C) An origin of replication (ORI) is present.
D) They can detect RNA in cells.
E) They must accept DNA of desired size.

Accepted Answer

Vectors are primarily used in molecular biology for cloning, sequencing, and manipulating DNA. They do not have the capability to detect RNA in cells. This function is typically performed by other molecular biology tools and techniques, such as reverse transcription PCR (RT-PCR) or RNA sequencing (RNA-seq), not by vectors themselves.
