D1.2.7—Complementary base pairing question 1
[Maximum number: 3]
DNA research, involving biotechnology, has led to benefits for society but has given rise to some controversy.
Outline how translation depends on complementary base pairing.
a. translation converts a sequence of mRNA nucleotides/codons to a sequence of amino acids/polypeptide/protein
b. «triplets of» nucleotides/bases on «activated» tRNAs pair with complementary «triplets of» nucleotides/bases on mRNA / vice versa
c. base pairing occurs when adenine/A pairs with uracil/U and guanine/G pairs with cytosine/C
d. specific amino acids are attached to specific of tRNA
e. mRNA has codons AND tRNA has anticodons
