Abstract

T4 polynucleotide ligase efficiently catalyzes the head-to-tail joining of the ribo-oligoadenylates, r-(pA)8 and r-(pA)10, in the presence of high molecular weight deoxypolythymidylate. The enzyme also catalyzes the joining of deoxy-oligothymidylates, e.g., d-(pT)10, in the presence of ribopolyadenylate. The enzyme failed to bring about the joining of r-(pA)10 when poly r-U was used as the template, although a slow formation of the expected activated intermediate from r-(pA)10 was detected.

Evidence of surface water ice on the moon
A study reports evidence of water ice on the moon’s surface, discerned via a signature in the near-infrared reflectance spectra that suggests the ice was formed by slow condensation due to impact or water migration through the lunar exosphere.
