Identify the types of point mutations depicted. missense mutation nonsense mutation silent mutation

To identify the type of point mutation depicted in the process of adding a methyl group to a tRNA molecule, resulting in the formation of Glycine, we need to understand the definitions of the three types of point mutations mentioned:1. Missense Mutation: This type of mutation occurs when a single nucleotide change results in the substitution of one amino acid for another in the protein product.2. Nonsense Mutation: This mutation occurs when a single nucleotide change results in a premature stop codon, leading to the truncation of the protein product.3. Silent Mutation: This mutation occurs when a single nucleotide change does not result in a change in the amino acid sequence of the protein product due to the redundancy of the genetic code.Given the details of the picture, the process described is not a point mutation in DNA but rather a post-transcriptional modification of tRNA, where a methyl group is added to the tRNA molecule. This modification does not change the nucleotide sequence of the tRNA or the DNA that encodes it. Instead, it is a form of RNA editing that can affect the function of the tRNA during protein synthesis.Since the image details do not describe a change in the nucleotide sequence that would lead to a change in the amino acid sequence of a protein, none of the point mutations listed (missense, nonsense, or silent) are depicted. The process described is a post-transcriptional modification, not a point mutation.Therefore, based on the information provided:- The process is not a missense mutation because there is no substitution of one amino acid for another in a protein.- The process is not a nonsense mutation because there is no introduction of a premature stop codon.- The process is not a silent mutation because there is no change in the nucleotide sequence that leaves the amino acid sequence of a protein unchanged.Final Answer: None of the point mutations listed (missense, nonsense, or silent) are depicted in the process described.
