If a sequence of non-template strand is 5'-ATGTGACGAG-3', the sequence of anticodon on tRNA will be

Options

A. AUGUGACGAG
B. UACACUGCUC
C. ATGTGACGAG
D. AUGUGTCCTA

Answer

To determine the sequence of the anticodon on tRNA from the given non-template DNA strand, follow these steps:

### Step 1: Identify the Non-Template Strand
The given non-template strand is:
5'-ATGTGACGAG-3'

### Step 2: Transcribe the DNA Sequence to mRNA
To convert the non-template DNA strand into mRNA, we need to replace thymine (T) with uracil (U). The transcription process involves creating a complementary RNA strand from the DNA strand.

1. Write down the non-template DNA strand:
- 5'-ATGTGACGAG-3'

2. Replace T with U to get the mRNA sequence:
- A (Adenine) pairs with U (Uracil)
- T (Thymine) pairs with A (Adenine)
- G (Guanine) pairs with C (Cytosine)
- C (Cytosine) pairs with G (Guanine)

Thus, the mRNA sequence will be:
5'-AUGUGACGAG-3'

### Step 3: Determine the Anticodon Sequence
The anticodon on tRNA is complementary to the mRNA codons. To find the anticodon, we need to pair the bases of the mRNA sequence in the opposite direction (3' to 5').

1. Write down the mRNA sequence:
- 5'-AUG UGA CGA G-3'

2. Write the complementary bases for the anticodon:
- A pairs with U
- U pairs with A
- G pairs with C

Thus, the anticodon sequence will be:
3'-UAC ACU GCU C-5'

### Step 4: Write the Anticodon in 5' to 3' Direction
Since we typically write sequences from 5' to 3', we can reverse the order:
5'-CUG UCA UGA-3'

### Final Answer
The sequence of the anticodon on tRNA is:
5'-CUG UCA UGA-3'
