Question

Which of the following statements regarding vectors is FALSE? ______

A) Cloning vectors frequently contain sequences necessary for expression of inserted sequences.
B) Vectors are usually autonomously replicating DNA molecules.
C) A useful vector contains multiple restriction sites for insertion of DNA.
D) Vectors are generally over 100,000 base pairs in size.
E) Cloning vectors include a "marker" to facilitate identification of cells containing them.

Answer 1

The statement that is FALSE regarding vectors is D) Vectors are generally over 100,000 base pairs in size.

Step-by-step explanation:

The statement that is FALSE regarding vectors is D) Vectors are generally over 100,000 base pairs in size.

Cloning vectors are DNA molecules used to insert foreign DNA and allow for its replication. They are typically small circular DNA molecules called plasmids. While they can vary in size, they are generally smaller than 100,000 base pairs in size. This is because larger vectors, such as bacteriophage vectors, are needed to accommodate long inserts, such as in the case of a large mammalian genome.
