Question

1. the amino acids for rna codons are given in the chart below.according to the chart, which amino acids are coded for by the following portion of an mrna strand?auggauuac auca methionine, aspartic acid, tyrosine, isoleucineb methionine, glycine, leucine, isoleucinec tyrosine, leucine, methionined threonine, aspartic acid, cysteine, isoleucine

Explanation:

Step1: Split mRNA into codons

Split the mRNA strand AUGGAUUACAUUC into 3-base codons:
$\text{AUG}, \text{GAU}, \text{UAC}, \text{AUC}$

Step2: Match codons to amino acids

Use the provided codon chart to find each amino acid:

• $\text{AUG}$ = Start/Methionine
• $\text{GAU}$ = Aspartic acid
• $\text{UAC}$ = Tyrosine
• $\text{AUC}$ = Isoleucine

Step3: Match to options

Compare the resulting amino acid sequence to the given options.

Answer:

A. methionine, aspartic acid, tyrosine, isoleucine
