Production of a human protein in bacteria by genetic engineering is possible because:

1.	Bacterial cells can carry out the RNA splicing reactions
2.	The mechanism of gene regulation is identical in humans and bacteria
3.	The human chromosome can replicate in bacterial cell
4.	The genetic code is universal
