In DNA technology, the term 'vector' can refer to:
A
The enzyme that cuts DNA into restriction fragments.
B
The sticky end of a DNA fragment.
C
A SNP marker.
D
A vehicle used to transfer DNA into a living cell.
Verified step by step guidance1
Understand the context: In DNA technology, a 'vector' is a tool used to introduce foreign genetic material into another cell.
Identify the role of a vector: It acts as a vehicle to transfer DNA, which can be a plasmid, virus, or other systems that can carry DNA into a host cell.
Differentiate from other terms: A restriction enzyme cuts DNA, sticky ends are the overhangs created by these cuts, and SNP markers are variations in a single nucleotide.
Recognize the application: Vectors are crucial in genetic engineering, gene therapy, and cloning as they facilitate the insertion of new genes into organisms.
Conclude with the correct definition: A vector is specifically used to transfer DNA into a living cell, enabling the study and manipulation of genes.
