Question

1. what would the difference be between the two mrna strands below when converted to amino acids? note: use the amino acid decoding chart if needed. normal strand: aga-ucg-agu mutant strand: aca-ucg-agu

Explanation:

Step1: Translate normal strand

Using the codon chart, AGA codes for Arg (Arginine), UCG codes for Ser (Serine), AGU codes for Ser (Serine). So the normal strand translates to Arg - Ser - Ser.

Step2: Translate mutant strand

Using the codon chart, ACA codes for Thr (Threonine), UCG codes for Ser (Serine), AGU codes for Ser (Serine). So the mutant strand translates to Thr - Ser - Ser.

Answer:

The normal strand (AGA - UCG - AGU) translates to Arginine - Serine - Serine. The mutant strand (ACA - UCG - AGU) translates to Threonine - Serine - Serine. The difference is that the first amino acid in the normal strand is Arginine and in the mutant strand it is Threonine.
