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 of the given statements regarding translation are correct, we will analyze each statement one by one.

### 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. This reaction results in the release of a water molecule (condensation reaction) and creates a covalent bond known as a peptide bond. 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 known as the cellular factories for protein synthesis. They are composed of ribosomal RNA and proteins and play a crucial role in translating mRNA into polypeptide chains (proteins). 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 a critical step in translation where amino acids are attached to their respective tRNA molecules. This process requires energy, which is provided by ATP. The enzyme aminoacyl-tRNA synthetase catalyzes this reaction, converting ATP into AMP and releasing a phosphate group. Therefore, this statement is **correct**.

### Conclusion
After analyzing all three statements:
- Statement (a) is correct.
- Statement (b) is correct.
- Statement (c) is correct.

Thus, all three statements are correct with respect to translation.

### Final Answer
All the given statements (a), (b), and (c) are correct.
