The main purpose of vectors in genetic engineering is to transfer genetic material. Vectors are tools used to introduce DNA into host cells. This can involve carrying genes of interest from one organism to another, enabling researchers to manipulate genetic information for various purposes, such as producing proteins, studying gene function, or developing genetically modified organisms.

Vectors, such as plasmids, viruses, or artificial chromosomes, are specially designed to ensure that the inserted genetic material can be effectively incorporated and expressed within the target cells. They often carry selectable markers that allow for easy identification of successfully transformed cells, making it easier to study the effects of the introduced genes.

The other options do not accurately reflect the primary function of vectors in genetic engineering. While vectors may influence growth indirectly by introducing genes that can enhance certain traits, their fundamental role centers on the transfer of genetic material.
