Expression vectors
A) are useful for analyzing RNA transcription patterns.
B) are useful for isolating large amounts of DNA.
C) can be used to make large amounts of protein in E. coli cells.
D) are useful only in prokaryotic cells, and cannot be expressed in eukaryotic cells.
E) are used to create SNPs for DNA microarrays.

Question

Quizplus · Accepted Answer

Expression vectors are designed to produce large amounts of proteins in host cells, usually bacteria such as E. coli. These vectors contain a promoter, a gene of interest, and other elements necessary for expression, such as a ribosome binding site and a transcription terminator. When these vectors are introduced into host cells, the cells will transcribe and translate the gene of interest, producing a large amount of protein. This makes expression vectors useful in biotechnology research and drug development.
