Question 1

Steps of protein synthesis

Answer 1

1) the double helix is unwound and unzipped
2) Free RNA nucleotides form complementary base pairs with one strand of DNA bases
3) The DNA strand is known as the template strand
4) weak hydrogen bonds form between base pairs (catalysed by RNA polymerase )
5) sugar phosphate bonds form between RNA nucleotides
6) the mRNA coding strand peels of the DNA strand and leaves the nucleus
7) mRNA attaches to a ribosome
