WebSo, all tRNA contains one thymine residue in the T loop. tRNA stands for transfer RNA, and functionally it is associated with the task of transferring cognate amino acids to the … WebIn DNA, the evolutionary substitution of thymine for uracil may have increased DNA stability and improved the efficiency of DNA replication (discussed below). Uracil pairs with adenine through hydrogen bonding. When base pairing with adenine, uracil acts as both a hydrogen bond acceptor and a hydrogen bond donor.
