Homework Statement
I am not able to clearly understand the role of t-RNA in the synthesis of proteins using m-RNA as a template.
please explain how does a t-RNA supply an amino acid??

Homework Equations
The Attempt at a Solution
t-RNA, or transfer RNA, is a type of RNA molecule that plays a crucial role in protein synthesis. Its main function is to carry amino acids to the ribosome, where they are joined together to form a protein chain.
t-RNA has a specific sequence of three nucleotides, called an anticodon, that binds to a complementary sequence of three nucleotides, called a codon, on the messenger RNA (mRNA) strand. Each anticodon corresponds to a specific amino acid, so the t-RNA molecule knows which amino acid to bring to the ribosome.
Yes, mutations in the genes that code for t-RNA molecules can lead to genetic diseases. This is because t-RNA is critical for the accurate translation of the genetic code into proteins. Mutations in t-RNA genes can result in misreading of the genetic code, leading to the production of abnormal proteins.
After delivering an amino acid to the ribosome, t-RNA is released and can be reused in protein synthesis. This is made possible by the enzyme aminoacyl-tRNA synthetase, which attaches the correct amino acid to each t-RNA molecule. This recycling process is important for the efficient production of proteins in the cell.
Yes, there are several types of post-transcriptional modifications that can occur to t-RNA molecules. These modifications can alter the structure and function of t-RNA, allowing it to perform specialized roles in protein synthesis. Examples of modifications include adding chemical groups or changing the sequence of nucleotides in the t-RNA molecule.
