II. Explain why a poi ryk98 +, xk tqlylf4j6gk40bsnt mutation c6 f uskxhef3576uq2pof CAU to CAG would cause a change in the polypeptide sequence of a protein but a point mutation of CAU to CAC would no7epcxq3kh2s uf65 uf6 t cause any change in the polypeptide sequence.




参考答案:
CAU is the codon for histone/His.
CAC is also a codon for histone/His.
CAG is the codon for glutamine/Gln/a different amino acid.
The genetic code is degenerate/more than one codon can be translated to the same amino acid. (Accept alternative phrasing)
