Q
1.
A
Gene for desired polypeptide unwinds and unzips as DNA helicase breaks hydrogen bonds between complementary bases.
2
Q
2.
A
Free RNA nucleotides bind to exposed complementary bases (U with A) on the template strand using RNA polymerase to build the sugar phosphate backbone.
3
Q
3.
A
mRNA complementary to template strand is formed, and leaves nucleus through nuclear pore.
