Question

What are the two types of tRNA which carry methionine?

Answer 1

Hint: A transfer RNA (formerly known as sRNA or soluble RNA) is an RNA-based adaptor molecule. It has a length of \[76 - 90\] nucleotides and serves as a link between mRNA and the amino acid sequence of proteins. The shape of transfer RNA can change at each of the three stages, although the secondary structure is the most stable and researched.
The primary structure, secondary structure (cloverleaf structure), and tertiary structure of tRNA can all be investigated.

Complete answer:
Methionine is the first amino acid in the synthesis of all proteins. A unique sort of initiation codon that sets the commencement of the reading frame is a signal to initiate a polypeptide chain. The AUG triplet is commonly used as the start codon. GUG, on the other hand, is utilised by bacteria. Methionine is represented by the AUG codon. Methionine is carried by two forms of tRNA, one of which is employed to detect AUG codons during elongation and the other during initiation.
UAC is the anticodon on the tRNA that delivers methionine to the ribosome, whereas AAU, AAC, GAA, GAG, GAU, and GAC are the anticodons on tRNA that provide leucine to the ribosome. mRNA goes from the nucleus to the cytoplasm after transcription from DNA and processing in the nucleus.
The amino acid methionine is specified by the codon AUG, also known as the start codon. As a result, methionine is the first amino acid to dock in the ribosome during protein synthesis. Tryptophan is unique in that it is the only amino acid for which a single codon has been designated.

Note:
The genetic code describes the relationship between the sequence of DNA bases (such as A, C, G, and T) in a gene and the associated protein sequence that it encodes. The cell can read the gene's sequence in groups of three bases. There are 64 codons in total, as we all know. 61 of these, however, are amino acids, with the remaining three serving as stop signals.
