Which codon is the start signal for translation?

The ribosome workbench uses the AUG codon as a universal signal to begin translation. The AUG start codon signals the ribosome to place in the amino acid methionine because the tRNA that has methionine attached to it has the anticodon sequence UAC. Therefore the tRNA will temporarily bind to the mRNAs sequence.

hope this helps.

Answer246 k;

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b
