5'-Terminal m-7G(5')ppp(5')G-m-p in vivo: identification in reovirus genome RNA.

Origin of Ribonuclease P RNA ( M 1 RNA )

The origin of RNase P RNA is yet an unsolved problem, although one of us (K.O.) formerly pointed out some sequence similarity between RNase P RNA and virusoids (Ohnishi, 1992). Eigen hypothesized that tRNA is the rst gene from theoretical standpoint. On the other hand, we have postulated polytRNA theory (Ohnishi; Endocytobiology V, 407: 1993; Ann. N.Y. Acad. Sci. 707: 524, 1993; Ohnishi et al.;...

کدهای ثابت دوری از طول p^s روی حلقه (r= f_(p^m )+uf_(p^m

کدهای پایادوری نقش ویژه ای را در نظریه ی کدهای تصحیح کننده ی خطا بازی می کنند. مهمترین نوع از این کدها، کدهای دوری هستند. در این پایان نامه پس از بیان مقدماتی از جبر، قواعد و فواصل همینگ برای کدهای منفی دوری که نوع خاصی از کدهای پایادوری هستند بیان می شوند. در ادامه کدهای پایادوری را روی حلقه r=f_(p^m )+uf_(p^m ) معرفی می کنیم،که در آن f_q=f_(p^m ) از مرتبه q است و u متغیر است. سپس قواعد و فواص...

HYPERIDEALS IN M-POLYSYMMETRICAL HYPERRINGS

An M-polysymmetrical hyperring $(R,+,cdot )$ is an algebraic system, where $(R,+)$ is an M-polysymmetrical hypergroup, $(R,cdot )$ is a semigroup and $cdot$ is bilaterally distributive over $+$. In this paper, we introduce the concept of hyperideals of an M-polysymmetrical hyperring and by using this concept, we construct an ordinary quotient ring. Finally, the fundamental theorem of homomorphi...

The 5'-terminal nucleotide sequences of the double-stranded RNA of human reovirus.

The 5'-terminal nucleotide sequences of human reovirus double-stranded RNA were determined after labeling the RNA with [(32)P]phosphate by polynucleotide kinase. The 5' terminal were labeled to only a limited extent prior to sequential oxidation, beta-elimination, and phosphomonoesterase treatment, indicating that the terminal phosphates were in a modified, blocked configuration. Each genome se...
