16.Termination codons differ from other codons in that:
They only recognize a single tRNA
They are capable of binding to many different tRNAs
They bind to release factors instead of tRNAs
They only specify a single amino acid
Termination codons do not differ from other codons

An mRNA codon may pair with more than one transfer RNA
Several mRNA codons may pair with a single transfer RNA
There are too many tRNAs present to account for the number of amino acids
Most mRNA codons can pair with only a single transfer RNA
tRNAs wobble when attached to an mRNA
