Read the following statements ,(a). A péptide bond is formed between COOH group of 1st amino acid and NH, group of 2nd amino acid. Br (b)-Ribosome is the cellular factory responsible for synthesising proteins. Br (c) -Activation of amino acids accurs in the presence of ATP.Which of the given statements are correct wrl. translation?

Options

A. a and b only
B. b and c only
C. a and c only
D. a, b and c

Answer

To determine which statements about translation are correct, let’s analyze each statement step by step.

### Step 1: Analyze Statement (a)
**Statement (a)**: A peptide bond is formed between the COOH group of the 1st amino acid and the NH2 group of the 2nd amino acid.

- **Explanation**: A peptide bond is indeed formed between the carboxyl group (COOH) of one amino acid and the amino group (NH2) of another amino acid. During this process, a molecule of water is released (a condensation reaction), and the bond formed is called a peptide bond or amide linkage. Therefore, this statement is **correct**.

### Step 2: Analyze Statement (b)
**Statement (b)**: Ribosome is the cellular factory responsible for synthesizing proteins.

- **Explanation**: Ribosomes are indeed the cellular structures where protein synthesis occurs. They read the mRNA sequence and translate it into a polypeptide chain by linking amino acids together in the order specified by the mRNA. Thus, this statement is also **correct**.

### Step 3: Analyze Statement (c)
**Statement (c)**: Activation of amino acids occurs in the presence of ATP.

- **Explanation**: The activation of amino acids is the process where amino acids are attached to their corresponding tRNA molecules, a process that requires energy. This energy is provided by ATP, which is hydrolyzed to AMP and pyrophosphate (PPi) during this activation. Hence, this statement is **correct**.

### Conclusion
All three statements (a), (b), and (c) are correct regarding the process of translation.

### Final Answer
All statements are correct.
