TLDR
The analysis of spacer DNA by molecular cloning and its organization in the genome by Southern transfer analysis reveal both length and sequence variation of the spacer.
Abstract
The complete repeating unit of the human ribosomal RNA gene has been reconstructed by the cloning of approximately 27 kilobases (kb) of non-transcribed spacer. The structure of this tandemly repeated gene can now be studied in its entirety. We report the analysis of spacer DNA by molecular cloning and its organization in the genome by Southern transfer analysis. These studies reveal both length and sequence variation of the spacer. Sequence variations are distributed throughout the spacer while the length variations exist near the 5' end of the transcript and just beyond the 3' end. The human spacer shares extensive homology with primates but little with other mammals. Within the primates the degree of homology reflects the rapid evolutionary changes characteristic of the primate group.

A census of human RNA-binding proteins.

TL;DR: This work presents a census of 1,542 manually curated RBPs that are analysed for their interactions with different classes of RNA, their evolutionary conservation, their abundance and their tissue-specific expression, a critical step towards the comprehensive characterization of proteins involved in human RNA metabolism.

The nucleolus: A structural and functional interpretation

TL;DR: This review addresses the problem of understanding nucleolar morphology in terms of nucleolar function by reviewing in situ-cytochemical results that have not led to a generally accepted view on the structure-function correlation for nucleoli.

Human ribosomal RNA gene arrays display a broad range of palindromic structures

TL;DR: Findings show that rRNA genes are a mosaic of canonical and (presumably nonfunctional) palindromic units that may be altered by factors associated with genomic instability and pathology.

Role of platinum-DNA adduct formation and removal in cisplatin resistance in human ovarian cancer cell lines

TL;DR: A role for DNA repair and alterations in interstrand cross-link formation in cisplatin resistance is supported and evidence for heterogeneous interstr and cross- link formation in the genome is provided.

Construction and characterization of new cloning vehicles. II. A multipurpose cloning system.

TL;DR: In vitro recombination techniques were used to construct a new cloning vehicle, pBR322, which is a relaxed replicating plasmid, does not produce and is sensitive to colicin E1, and carries resistance genes to the antibiotics ampicillin (Ap) and tetracycline (Tc).
