During translation, a tRNA molecule carrying a specific amino acid recognizes the corresponding codon on the mRNA through its anticodon. A mutation occurs in the anticodon loop of a tRNA specific for alanine, changing it from 3'-CGI-5' to 3'-CCI-5'. Assuming the wobble hypothesis applies, what is the MOST LIKELY consequence of this mutation?
The tRNA will no longer recognize any codons.
The tRNA will insert glycine into the polypeptide chain instead of alanine.
The tRNA will still carry alanine but will recognize different alanine codons.
The mutation will have no effect on protein synthesis.
There is no tRNA for codon which has sequence
