In IB Biology SL D1.2.7, tRNA anticodons pair with complementary mRNA codons by hydrogen bonding. Specific amino-acid attachment to each tRNA helps ensure the correct amino acid is added.
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 tRNA |
| e | mRNA has codons AND tRNA has anticodons |
