To determine the amino acid sequence encoded by the RNA sequence UUUCCUCAA, we need to translate the RNA sequence into its corresponding amino acid sequence. The translation occurs by reading the RNA in sets of three nucleotides at a time. Each set of three nucleotides, known as a codon, corresponds to a specific amino acid or a stop signal during protein synthesis. Let's translate the provided RNA sequence:

The RNA sequence: UUUCCUCAA

First codon: UUU

Second codon: CCU

Third codon: CAA

Now, we can use a genetic codon table that matches each RNA codon with its corresponding amino acid to find out the amino acids for these codons:

UUU codes for the amino acid Phenylalanine (abbreviated as Phe or F).

CCU codes for the amino acid Proline (abbreviated as Pro or P).

CAA codes for the amino acid Glutamine (abbreviated as Gln or Q).

So, the RNA sequence UUUCCUCAA encodes the amino acid sequence:

Phenylalanine - Proline - Glutamine

Using the single-letter abbreviations for each amino acid, this sequence is summarized as: F - P - Q
