Question

The discovery of amber mutations by Sydney Brenner and colleagues was a group of mutations that were eventually shown to be.. a unusual amino acid that generated an amber color in the affected bacteria. b. a deletion mutation that creates a translational frameshift. Insertion mutation that creates a translational frameshift. d. premature stop codon within the gene's open reading frame. e previously unknown signal for speeding the translation process (as in "an amber light means speed up before the light turns red 7. Moving to another question will save this response.

Answer 1

Amber mutation is the one whereby the mutation changes a sense codon into a stop codon which leads to the termination of translation of the protein in between.

The correct answer is-

d- premature stop codon within the gene's open reading frame
