[Participation of Proteins of the CPSF Complex in Polyadenylation of Transcripts Read by RNA Polymerase III from SINEs].

SINEs are mobile genetic elements of multicellular eukaryotes that arose during evolution from various tRNAs, as well as from 5S rRNA and 7SL RNA. Like the genes of these RNAs, SINEs are transcribed by RNA polymerase III. The transcripts of some mammalian SINEs have the capability of AAUAAA-dependent polyadenylation, which is unique for transcript generated by RNA polymerase III.

Assessing Genetic Variability and Population Structure of (Black Alder) in Kazakhstan Using SSR Markers.

plays a crucial role in flood control, riverbank stabilization, and water purification. Recognized for its ecological significance, it is listed in the Red Book of Kazakhstan. This study investigated the genetic variability of populations in Kazakhstan, analyzing 78 trees from seven populations in the Bayanaul mountain forest massif and the northern Turgay regions using 12 SSR markers.

Ere, a Family of Short Interspersed Elements in the Genomes of Odd-Toed Ungulates (Perissodactyla).

Short Interspersed Elements (SINEs) are eukaryotic retrotransposons transcribed by RNA polymerase III (pol III). Many mammalian SINEs (T SINEs) contain a polyadenylation signal (AATAAA), a pol III transcription terminator, and an A-rich tail in their 3'-end. The RNAs of such SINEs have the capacity for AAUAAA-dependent polyadenylation, which is unique to pol III-generated transcripts.

Revised checklist of endemic vascular plants of Kazakhstan.

We compiled a checklist of endemic vascular plants occurring in Kazakhstan, employing an exhaustive examination of literature sources, herbarium collections, databases and field observations. Our study reveals that 451 taxa can be considered endemic to Kazakhstan, constituting 7.97% of the total vascular plant diversity in the country.

SINEs as Potential Expression Cassettes: Impact of Deletions and Insertions on Polyadenylation and Lifetime of B2 and Ves SINE Transcripts Generated by RNA Polymerase III.

Short Interspersed Elements (SINEs) are common in the genomes of most multicellular organisms. They are transcribed by RNA polymerase III from an internal promoter comprising boxes A and B. As transcripts of certain SINEs from mammalian genomes can be polyadenylated, such transcripts should contain the AATAAA sequence as well as those called β- and τ-signals.
