The technique used to introduce foreign DNA into cells by applying a brief electric pulse is: MCQ with Answer and Explanation

Explanation:
The liver synthesizes most plasma proteins, including albumin (osmotic pressure) and clotting factors (I, II, VII, IX, X). The kidneys produce erythropoietin and active vitamin D, pancreas digestive enzymes, spleen filters.

Explanation:
The Ti (tumor-inducing) plasmid from Agrobacterium tumefaciens is a natural plant genetic engineer. It transfers T-DNA into the plant genome, making it an effective vector for introducing foreign genes in plant genetic engineering. pBR322 is a common E. coli cloning vector. Bacteriophage lambda and cosmids are used in animal/bacterial systems. Ti plasmid has revolutionized GM crop development.

Explanation:
A neuron consists of a cell body (soma), dendrites, and an axon. Dendrites are short, branched processes that receive impulses and conduct them towards the cell body. The axon is a long, single, cylindrical fiber that conducts nerve impulses away from the cell body to other neurons, muscles, or glands. The myelin sheath is an insulating layer around the axon.
