chloroplast

a. DNA is replicated;

b. unwinding of the double helix/DNA (by helicase)

OR

supercoiled DNA is relaxed (by gyrase);

c. hydrogen bonds broken

OR

strands separate;

d. synthesis of new strands of DNA (by DNA polymerase);

e. DNA replication occurs semi-conservatively

OR

existing strand used as a template (for a new strand of DNA);

OR

DNA replication is continuous on the leading strand, but discontinuous on the lagging strand;

f. copying base sequences occurs through complementary base pairing (in both transcription and replication);

g. DNA is transcribed;

h. synthesis of RNA/mRNA (by RNA polymerase);

i. copy of a gene produced/only one gene transcribed;

j. introns are removed;

k. RNA/mRNA exported/moves to the cytoplasm;
