The development and use of ushered in the era of genomics when geneticists began planning ways to sequence the 3.2 billion nucleotides in the human genome.

The technology involves DNA molecules from two different species. It is joined and then inserted into a host to produce new genetic combinations. It is a great contribution to studies relating to science, medicine, agriculture and industry.

p

explanation:

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
