Answer;
Nucleus
Micropipettes and gene guns are mechanical vectors that introduce recombinant DNA directly into the cell’s nucleus of a host cell.
Step-by-step explanation;
- Micropipettes are used to transfer very small and exact volumes of liquids in either milliliters or microliters, which are the measurements of volume most often used in genetic engineering.
- Microinjection is the process of using micropipette to inject liquid substances at microscopic level.
- The process is used to introduce a vector into a single cell in recombinant DNA technology. It may also be used in cloning of organisms.
