Which of the following RNA strings could translate into the amino acid string PRTEIN? (Select all that apply.)

To determine which of the given RNA strings could translate into the amino acid string PRTEIN, we need to use the genetic code to match the codons in the RNA with the corresponding amino acids.

The genetic code is a set of rules that determines how the sequence of nucleotides in RNA is translated into the sequence of amino acids in a protein. Each codon, which consists of three nucleotides, corresponds to a specific amino acid or a stop signal.

Let's analyze each RNA string and check if it can translate into the amino acid string PRTEIN:

1. AUGCGUAGU: This RNA string starts with the codon AUG, which codes for the amino acid methionine (M). The next codon, CGU, codes for arginine (R), and AGU codes for serine (S). However, there is no codon that corresponds to the amino acid T. Therefore, this RNA string cannot translate into the amino acid string PRTEIN.

2. CCUAGGUGA: The first codon, CCU, codes for proline (P), AGG codes for arginine (R), and UGA is a stop codon. However, there is no codon that corresponds to the amino acids T and E. Therefore, this RNA string cannot translate into the amino acid string PRTEIN.

3. UUUCCCGAA: The first codon, UUU, codes for phenylalanine (F), CCC codes for proline (P), and GAA codes for glutamic acid (E). However, there is no codon that corresponds to the amino acid T. Therefore, this RNA string cannot translate into the amino acid string PRTEIN.

4. GGGAAAUAC: The first codon, GGG, codes for glycine (G), AAA codes for lysine (K), and UAC codes for tyrosine (Y). However, there is no codon that corresponds to the amino acids T and E. Therefore, this RNA string cannot translate into the amino acid string PRTEIN.

Based on the analysis, none of the given RNA strings can translate into the amino acid string PRTEIN.
