Analysis of Human Transfer RNA Gene Heteroclusters

Description: Two phage lambda clones encompassing human tRNA genes have been isolated from a human gene library harbored in bacteriophage lambda Charon-UA. One of the clones (designated as hLeuU) containing a 20-kb human DNA fragment was isolated and found to contain a cluster of four tRNA genes. An 8.2-kb Hindlll fragment encompassing the four tRNA genes was isolated from the 20-kb fragment and subcloned into pBR322 for restriction mapping and DNA sequence analysis. The four tRNA genes are arranged as two… more

Functional Significance of Sympathetic Fiber Ingrowth in the Habenula

Description: The physiological significance of noradrenergic sympathohabenular ingrowth following medial septal lesions was investigated. Following septal lesions, sympathetic fibers originating in the superior cervical ganglia are known to sprout into the medial habenular nuclei, and into the hippocampal formation. Previous work involving sympathohippocampal ingrowth showed that firing rates in septal animals with no ingrowth showed that firing rates in septal animals with no ingrowth were higher than rate… more

The Nucleotide Sequences of a Mammalian Tyrosine Transfer RNA and a Cluster of Human Transfer RNA Genes

Description: Tyrosine tRNA was isolated from bovine liver and its nucleotide sequence was determined using in vitro 32p_ labeling techniques. Several important structural features of the tRNA are: the presence of gal-Q in the first position of the anticodon, acp3U at position 20, and a pair of adjacent N,N-dimethylguanosines (residues 26 and 27). A human DNA fragment harbored in a lambda phage clone was isolated, and restriction enzyme analysis revealed the presence of three tRNA genes in a 6.0-kb BamHI sub… more
