[ID-similar sequences in various types of DNA clones].
The sequence of rat ID repeat was compared with those of Escherichia coli, Drosophila melanogaster, chicken, rat, mouse and human clones and clones with t-RNA gene from EMBL-5 date bank. This comparison was made bearing on the determination of the level of mutual information between the sequences compared. The non-canonical similarity of the ID repeat sequence with the tRNA genes was found. It is revealed by the conservation of purine or pyrimidine sites in the sequences compared. In human and mouse clones purine-pyrimidine copies of rat ID sequence were also found. In some cases these sequences were flanked by short direct repeats, they contained also poly(A)-like sequences. The possible functional meaning and evolutional origin of the revealed relations are discussed.
