Part AtRNAs contain 4 arms, each characterized by the presence of certain modified bases or specific nucleotide sequences having a specific function. Which of the following are you likely to find in the anticodon of tRNA?**CAA SEQUENCE**1. **Dihydrouridine** - Chemical Structure: Displays a pentagon shape with nitrogen and oxygen atoms. Hydrogen atoms are attached to the structure, with ribose indicated. 2. **Ribothymidylic acid (T)** - Chemical Structure: Shows a hexagon with carbon, oxygen, nitrogen, and methyl group attached. It has a double-bonded oxygen and a ribose sugar part.3. **Pseudouridylic acid (ψ)** - Chemical Structure: Consists of a blue-colored hexagon with carbon, oxygen, and nitrogen elements. It has a ribose sugar attached and highlighted bonds. These diagrams illustrate the chemical structure of three bases that could be present in the anticodon region of tRNA, contributing to its unique function. **Educational Transcription: Structure of Nucleoside Derivatives**### DihydrouridineAt the top of the image, the chemical structure of dihydrouridine is displayed. It includes components typical of nucleosides such as ribose.### Nucleoside Derivatives:1. **Ribothymidylic Acid (T)** - Structure: A hexagonal structure with hydrogen, oxygen, and ribose components. - Key Feature: The ribose is highlighted in a yellow box. 2. **Pseudouridylic Acid (*Ψ*)** - Structure: Similar to ribothymidylic acid with a hexagonal formation. - Key Feature: The ribose component is also highlighted, but in a blue box.3. **Inosinic Acid (I)** - Structure: A more complex structure including nitrogen rings. - Key Feature: The ribose is highlighted in a yellow box, showing the typical sugar component connected to the nucleobase.The diagram highlights the role of ribose in different nucleoside structures, crucial for understanding nucleic acid chemistry. Each derivative serves specific roles within RNA and DNA, influencing structure and function.

tRNA have 4 major arms and 1 variable arm. The 4 major arms of tRNA are ; D arm Anticodon arm TψC arm and Amino acid arm. Characteristic modified bases does specific functions in these arms.An anticodon of tRNA comprises a 3-base sequence that is complementary to the 3 bases of one or more mRNA codons. Many anticodons, instead of the usual A, C, G, or U, have I (Inosinic acid) in the first position which enables them to recognize 3 different mRNA codons. This is because 'I' can form hydrogen bonds with U, C and A . This enables the wobble base pairing. The anticodon arm of tRNA also contain pseudouridylic acic (ψ). Dihydrouridine (D) is found in the D arm, while ribothymidylic acid (T) is found in the TψC arm. D and T are not generally found in the anticodon arm. So, the correct answers are Inosinic acid (I) and pseudouridylic acic (ψ).
