A promoterless retroviral vector indicates that there are sequences in U3 required for 3' RNA processing.

Upstream sequences other than AAUAAA are required for efficient messenger RNA 3'-end formation in plants.

We have characterized the upstream nucleotide sequences involved in mRNA 3'-end formation in the 3' regions of the cauliflower mosaic virus (CaMV) 19S/35S transcription unit and a pea gene encoding ribulose-1,5-bisphosphate carboxylase small subunit (rbcS). Sequences between 57 bases and 181 bases upstream from the CaMV polyadenylation site were required for efficient polyadenylation at this si...

Pac1 endonuclease and Dhp1p 5'-->3' exonuclease are required for U3 snoRNA termination in Schizosaccharomyces pombe.

Maturation of some snoRNAs is dependent on RNase III-like endonuclease-mediated transcript cleavage, which serves as an entry for the nuclear exosome complex that trims the transcript at the 3'-end. Sequence deletions suggest this cleavage in the U3 snoRNA transcripts of Schizosaccharomyces pombe can induce transcript termination. Using mutational analyses, we demonstrate that the degree of cle...

Delivery of short hairpin RNA sequences by using a replication-competent avian retroviral vector.

While recent studies have demonstrated that retroviral vectors can be used to stably express short hairpin RNA (shRNA) to inhibit gene expression, these studies have utilized replication-defective retroviruses. We describe the creation of a replication-competent, Gateway-compatible retroviral vector capable of expressing shRNA that inhibits the expression of specific genes.

Why Believe That There Is a God?

This article presents an argument for the existence of God, showing that the evident phenomena are best explained by supposing that a God causes them. The argument is based on the inductive force of four very evident general phenomena: that there is a physical Universe; that it is governed by very simple natural laws; that those laws are such as to lead to the existence of human bodies; and tha...
