tRNA Anti-codon Wobble
It has been documented that tRNA wobbles in most of the amino acids attached to it making the third nucleotide of it's anti-codon redundant when signaling amino acid insertion as the mRNA is translated.
This phenomenon is applicable to all except which of the following two amino acids?
a- leucine and isoleucine
b- methionine and tryptophan
c- phenylalanine and tyrosine
d- arginine and glycine
PS: I am the author of this question, I made it myself
Wow this is a really good question! I know methionine is special, but didn't know Tryptophan is special too! :D
Thx lee, do come up with more questions please!:)
The genetic code is redundant and degenerate in that several codons code for the same amino acid so that a change in the third nucleotide may not matter and this is how silent mutations occur. The exceptions are methionine and tryptophan both of which have only one codon coding for them.
The AUG for methionine also serves as a start codon.
this question kinda requires us to know the 16*16 GENE BOX
