The sequence of nucleotides AUGCUUCUC indicates that it is a segment is

Options

A. Sense strand of DNA
B. Antisense strand of DNA
C. RNA
D. Polypeptide chain

Answer

To determine the nature of the nucleotide sequence AUGCUUCUC, we can follow these steps:

### Step 1: Identify the Components of the Sequence
The given sequence is AUGCUUCUC. We need to analyze the nucleotides present in this sequence.

### Step 2: Check for Uracil
In the sequence, we notice the presence of uracil (U). This is a key indicator because uracil is found in RNA but not in DNA. In DNA, thymine (T) is present instead of uracil.

### Step 3: Eliminate DNA Options
Since uracil is present in the sequence, we can eliminate the options that suggest it is a segment of DNA (both sense and anti-sense strands). Therefore, options indicating DNA are incorrect.

### Step 4: Determine if it is RNA
Given that uracil is present, the sequence must be a segment of RNA. RNA is characterized by the presence of ribose sugar and uracil instead of thymine.

### Step 5: Consider Other Options
The remaining options are RNA and polypeptide chain. Since we have established that the sequence is RNA, we can conclude that it is not a polypeptide chain. A polypeptide chain is made up of amino acids, which are encoded by mRNA sequences, but the sequence itself is not a polypeptide.

### Conclusion
Thus, the correct answer is that the sequence AUGCUUCUC indicates that it is a segment of RNA.

### Final Answer
The sequence of nucleotides AUGCUUCUC indicates that it is a segment of RNA.
