Q

Since the rough ER helps modify proteins that will be secreted from the cell, cells whose job is to secrete large amounts of enzymes or other proteins, such as liver cells, have lots of rough ER.

Q

Glyphosate-based herbicides all work on the same biochemical principle – they inhibit a specific enzyme that plants need in order to grow. The specific enzyme is called EPSP synthase. Without that enzyme, plants are unable to produce other proteins essential to growth, so they yellow and die over the course of several days or weeks.

Q

Transgenesis is when genes from one species are extracted and fused into genes of different species. This can be accomplished by blasting DNA into cells, utilizing a parasitic bacteria, or by cutting specific DNA sequences using Crisper Cas9, which the cell then repairs with modified DNA
Parasitic bacteria- incorporate desired gene into bacteria plasmid, plasmid incorporated into plant cell
