In the presence of a selenocysteine insertion (SECIS) element in the mRNA, the UCA anticodon translates into selenosysteine in many redox enzymes.In the absence of the SECIS element, the UCA is the umber stop codon.Which mRNA codon would the UCA anticodon pair with?Keep in mind that base-pairing occurs between antiparallel nucleic acids.

MCQs on the structure and function of DNA and RNA and how these nucleic acids are used to form proteins, and their importance in genetics and inheritance. Also covers DNA replication, transcription, gene expression, mutation and repair, recombination, molecular techniques, and appropriate molecular models.
