Each of these statements accurately describes features common to tRNA molecules. tRNAs are relatively small RNA molecules with lengths typically between 73 and 93 nucleotides. They are known for having unusual bases that are not found in other types of RNA, which arise from post-transcriptional modifications. A significant portion of the nucleotides in tRNA molecules form base pairs with each other, creating a characteristic cloverleaf structure in 2D and an L-shaped structure in 3D. Lastly, tRNAs often have a phosphate group attached to a guanine nucleotide at their 5′ end, denoted as pG.
