Genes for elongation factor EF‐1α in the brine shrimp Artemia

Abstract
A plasmid carrying a cDNA sequence coding for elongation factor EF-1α from Artemia was used to probe blots of mRNA and chromosomal DNA from Artemia. A messenger length for EF-1α corresponding to 1850 nucleotides was found. Southern blots pointed to a limited number (1–4) genes, coding for EF-1α. From an Artemia gene library a recombinant phage was isolated, which contains genomic sequences of EF-1α. S1-nuclease mapping indicated the presence of intervening sequences within this cloned gene.
