Code in RNA corresponding to AGCT in DNA.

Options

A. TACA
B. UCGA
C. TCGA
D. AGUC

Answer

To find the RNA code corresponding to the DNA sequence AGCT, we will follow these steps:

### Step 1: Identify the DNA Sequence
The given DNA sequence is AGCT.

### Step 2: Understand Base Pairing Rules
In DNA, the base pairing rules are as follows:
- Adenine (A) pairs with Thymine (T)
- Guanine (G) pairs with Cytosine (C)

When transcribing DNA to RNA, the base pairing rules change slightly:
- Adenine (A) pairs with Uracil (U) in RNA instead of Thymine (T)
- Guanine (G) still pairs with Cytosine (C)
- Cytosine (C) still pairs with Guanine (G)
- Thymine (T) in DNA pairs with Adenine (A) in RNA

### Step 3: Transcribe Each Base
Now, we will transcribe each base of the DNA sequence AGCT into RNA:
- A (Adenine) in DNA pairs with U (Uracil) in RNA.
- G (Guanine) in DNA pairs with C (Cytosine) in RNA.
- C (Cytosine) in DNA pairs with G (Guanine) in RNA.
- T (Thymine) in DNA pairs with A (Adenine) in RNA.

### Step 4: Write the RNA Sequence
Putting it all together, the RNA sequence corresponding to the DNA sequence AGCT is:
- A → U
- G → C
- C → G
- T → A

Thus, the RNA sequence is **UCGA**.

### Final Answer
The code in RNA corresponding to AGCT in DNA is **UCGA**.
