Structural analysis of templates and RNA polymerase III transcripts of Alu family sequences interspersed among the human beta-like globin genes

C H Duncan et al. Gene. 1981 Mar.

Abstract

Cloned DNA fragments form the human beta-like globin genomic region can be transcribed in vitro by RNA polymerase III. We have investigated the structure of two templates and their transcripts by DNA sequencing, size fractionation of ribonuclease T1 generated oligonucleotides, and ribonuclease H digestion of RNA : DNA duplexes. The data indicate the repetitive DNA sequences, members of the Alu family of interpersed 300 bp reiterated DNA, are imbedded in both templates. The RNAs transcribed from them are composed of an entire Alu family sequence at their 5' ends linked to 3' ends of non-repetitive sequence.
