Question

the genetic code, which specifies the amino acids coded for by specific mrna codons, is summarized in this table. it can be interpreted by locating the first letter of the codon in the left column and the second letter in the row at the top, identifying the box where the row and column meet, then finding the third letter in the corresponding column on the right. for example, the start codon aug codes for the amino acid methionine. order the following choices from most to least able to withstand point mutations to their mrna codons and still deliver the same results. start by choosing the first item in the sequence and clicking, dragging, or using your keyboard to select it. methionine glycine leucine stop codon

Explanation:

• Leucine: Has 6 codons (CUU, CUC, CUA, CUG, UUA, UUG). A point mutation is more likely to result in another leucine - coding codon.
• Glycine: Has 4 codons (GGU, GGC, GGA, GGG). There are more possibilities for a point mutation to still code for glycine compared to stop codons and methionine.
• Stop codon: There are 3 stop codons (UAA, UAG, UGA). A point mutation could change it to a non - stop codon.
• Methionine: Has only 1 codon (AUG). A single point mutation will always change it to a non - methionine - coding codon.

Answer:

leucine, glycine, stop codon, methionine
