摘要:
Oligonucleotides of the formula: 5'(U).sub.n -3' in which U is an identical or different radical of a natural or a synthetic nucleoside and n is a number from 2 to 200 comprising at least one structural unit of two consecutive nucleosides wherein one of the nucleotides is substituted in the 2'-position or wherein the nucleotides are substituted differently in their 2'-position and wherein the backbone is modified.

Oligonucleotide analogs are provided wherein phosphodiester inter-sugar linkages are replaced with four atom linking groups. Such linking groups include NR--C(O)--CH.sub.2 --CH.sub.2, NR--C(S)--CH.sub.2 --CH.sub.2, CH.sub.2 --NR--C(O)--CH.sub.2, CH.sub.2 --NR--C(S)--CH.sub.2, CH.sub.2 --CH.sub.2 --NR--C(O)--R--CH.sub.2, and CH.sub.2 --C(S)--NR--CH.sub.2. Methods for preparing and using these oligonucleotide analogs are also provided.
摘要:
A computer system utilizing an N bit word in which a directly addressable space is limited to 2.sup.N-1 words or 2.sup.N characters by the system architecture. Extension of this directly addressable space to 2.sup.N words is accomplished by a combination of a memory management circuit and a character selection signal instructions which allows both characters and words to be mixed in a first 2.sup.N-1 words of directly addressable space and words only to be addressed in a second 2.sup.N-1 words of directly addressable space.
