Structure of RNA
RNA (ribonucleic acid) is a nucleic acid molecule that is involved in various biological processes, including protein synthesis, gene regulation, and the transmission of genetic information. It is composed of a single-stranded chain of nucleotides, each consisting of a sugar molecule (ribose), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, or uracil).
There are three main types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Each type of RNA plays a specific role in gene expression and protein synthesis.
Structure of tRNA
Transfer RNA (tRNA) is responsible for carrying amino acids to the ribosome during protein synthesis. It has a distinctive cloverleaf-like structure, which is why it is the correct answer to this question.
Key features of tRNA structure
1. Four-arm structure: tRNA consists of four arms or loops - the acceptor stem, D arm, anticodon arm, and T arm. These arms are responsible for different functions of tRNA.
2. Acceptor stem: This arm contains the 3' end of tRNA, which binds to the corresponding amino acid. It is the site where amino acids are attached to tRNA through an ester bond.
3. D arm: The D arm is named after the presence of dihydrouridine (D) residues. It plays a role in the recognition of tRNA by specific enzymes during protein synthesis.
4. Anticodon arm: The anticodon arm contains the anticodon, which is a sequence of three nucleotides that is complementary to a specific codon on mRNA. It ensures the correct pairing between tRNA and mRNA during translation.
5. T arm: The T arm contains a sequence of nucleotides that is recognized by enzymes involved in aminoacylation (the attachment of the correct amino acid to tRNA).
6. Intraloop base pairing: The arms of tRNA are connected by intraloop base pairing, which stabilizes the cloverleaf structure and maintains the overall stability of tRNA.
Conclusion
Among the different types of RNA, transfer RNA (tRNA) has a structure resembling a cloverleaf. This unique structure is essential for the proper functioning of tRNA in carrying amino acids to the ribosome during protein synthesis.
