QUESTION 39
1.
In
DNA replication,

an entirely new
double helix is built using information in the sequence of amino acids

parental DNA
shatters into pieces, and joins with newly-synthesized pieces to fashion two
double helices from one

parental DNA
remains intact but guides formation of new double helices

DNA taken into the
body in the diet enters cells and joins the DNA

the parental DNA
splits and free nucleotides bond to their complements, building two DNA
molecules from one
