Function of tRNA. The job of tRNA is to read the message of nucleic acids, or nucleotides, and translate it into proteins, or amino acids. The process of making a protein from an mRNA template is ...
A transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length, that serves as the physical link between the mRNA and the amino acid sequence of proteins. tRNA does this by carrying an amino acid to the protein synthetic machinery of a cell as directed by a 3-nucleotide sequence in a messenger ...
Transfer RNA (tRNA) is a small type of stable RNA that carries an amino acid to the corresponding site of protein synthesis in the ribosome. It is the base pairing between the tRNA and mRNA that allows for the correct amino acid to be inserted in the polypeptide chain being synthesized.

Describe the structure of the tRNA molecule tRNA is composed of 80 nuclotides. Complimentary sequences in this molecule hydrogen bond with each other causing the molecule to fold upon itself into the general shape of an "L" with a loop that has the anticodon and an exposed 3" end that is the attachment site for an amino acid.
The three-dimensional structure of DNA was elucidated in 1953, earning James Watson and Francis Crick a Nobel Prize. But for years afterward, the structure of RNA remained elusive despite efforts by some of the same DNA experts to describe it.

Describe the structure and functions of tRNA. Structure Short, about 80 nucleotides Folded with four base-paired regions ... Explain what determines the primary structure of a protein and describe how a polypeptide must be modified before it becomes fully functional.
The structure of RNA is a single-stranded molecule made up of basic units called nucleotides that contain a nitrogenous base, a five-carbon sugar and a phosphate group. Although there is only one strand of RNA, as opposed to the two stranded double helix of DNA, it does not always follow a linear pattern.
tRNA, or transfer RNA, is the "decoder" of the mRNA message during protein translation. After transcription, tRNA is extensively modified to include nonstandard bases such as pseudouridine, inosine, and methylguanosine. By themselves, ribosomes cannot form a protein when the mRNA makes contact.
