Enzyme involved in combining amino acid to its particular tRNA

The enzyme that helps in combining amino acids to their particular tRNA is amino-acyl tRNA synthetase, also known as activating enzyme.

Explanation:

The process of translation involves the synthesis of proteins from the genetic information contained in mRNA. During translation, the mRNA sequence is decoded by the ribosome to determine the order and sequence of amino acids in the polypeptide chain. Each amino acid is carried to the ribosome by a specific transfer RNA (tRNA) molecule.

The process of attaching an amino acid to its corresponding tRNA molecule is a crucial step in protein synthesis. This is where the amino-acyl tRNA synthetase enzyme comes into play. This enzyme is responsible for catalyzing the attachment of the correct amino acid to its specific tRNA molecule. It ensures that the correct amino acid is attached to the corresponding tRNA molecule, thus maintaining the accuracy and specificity of protein synthesis.

Key points:
- Amino-acyl tRNA synthetase is the enzyme involved in combining amino acids to their particular tRNA molecules.
- This enzyme plays a vital role in maintaining the accuracy and specificity of protein synthesis.
- It catalyzes the attachment of the correct amino acid to its corresponding tRNA molecule.
- Each amino-acyl tRNA synthetase is specific for a particular amino acid and recognizes the specific tRNA molecule that carries that amino acid.
- The activation of amino acids by amino-acyl tRNA synthetase is an essential step in the translation process.

Summary:
The enzyme responsible for combining amino acids to their specific tRNA molecules is amino-acyl tRNA synthetase. This enzyme plays a crucial role in maintaining the accuracy and specificity of protein synthesis by ensuring that the correct amino acid is attached to its corresponding tRNA molecule. Each amino-acyl tRNA synthetase is specific for a particular amino acid and recognizes the specific tRNA molecule that carries that amino acid. The activation of amino acids by amino-acyl tRNA synthetase is an essential step in the translation process.
