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
The discovery of amber mutations by Sydney Brenner and colleagues was a group of mutations that...
An important validation of the genetic code occurred when George
Streisinger determined the amino acid sequence of bacteriophage T4
lysozyme and of mutants induced by proflavin, a dye with a planar
structure that can intercalate (fit) between successive base pairs
in DNA and induce frameshift mutations−that is, mutations involving
additions or deletions of a single base. Streisinger and colleagues
found that a particular single-base insertion mutation could be
suppressed, with wild-type function restored, by a mutation that
evidently involved a...
1) Which of the following mutations could result in a frameshift? A) a base insertion B) a base deletion C) a base substitution D) either A or B E) A, B, and C 2) Which of the following point mutations would be most likely to result in a non-functioning protein? A) a single base substitution in an intron B) a single base deletion near the end of the coding sequence C) a single base deletion in the codon following the...

What would be the composition of the canavanine selection plates
(see Lab 9) if we did not chose to select for the presence of the
gRNA plasmid?
Plate counting Last week you transformed the PMD2 plasmid that contains the ORNA sequence. The yeast cells were selected on a YNB + histidine + methionine plate in order to make sure that only the cells that contain the plasmid grow and give a colony. Simply count the number of colonies that grew...
