Nucleotide sequences of two nuclear tRNATyrgenes fromTriticum aestivum

Nucleotide sequences of two glutamine tRNAs from HeLa cells.

We reported previously that 4.5S RNAj, is associated with poly A RNAs of rodent cells (1). However, this molecule was not found in human, monkey, cat, mink, rabbit or chicken cells ^1) . In HeLa cells, several 4S RNAs are released from the poly A RNA fraction (1) . We determined the nudeotide sequence of one of the most abundant 4S RNA species in this fraction. Nudeotide sequence analysis was p...

Nucleotide sequences of two soybean U1 snRNA genes.

Southern blot analyses show that the soybean genome contains many U1 snRNA genes, both in tandem arrays and as isolated genes. We have cloned and sequenced two soybean U1 snRNA genes, U1a and U1b, which represent distinct multicopy tandem repeat elements. Sequence analysis of the first 46 nt of soybean embryo protoplast U1 snRNA by primer extension shows that sequences corresponding to U1a and ...

A two-phase strategy for detecting recombination in nucleotide sequences

Genetic recombination can produce heterogeneous phylogenetic histories within a set of homologous genes. Delineating recombination events is important in the study of molecular evolution, as inference of such events provides a clearer picture of the phylogenetic relationships among different gene sequences or genomes. Nevertheless, detecting recombination events can be a daunting task, as the p...
