Selenocysteine Biosynthesis

The video explains the biosynthesis of selenocysteine, a unique amino acid not among the standard 20. It details the synthesis pathway, starting from serine, involving specific tRNA and enzymes. The role of binding proteins and the mRNA's secis sequence in ensuring correct insertion of selenocysteine at the ribosome is highlighted. The video also discusses the differences in this process between eukaryotes and bacteria.

What is the codon for selenocysteine and how does it differ from the codon for serine?

Discuss the importance of the SECIS element in the mRNA for selenocysteine insertion.
