Average spacing of ribosomes on the majority of transcripts in embryos

Range 90 to 100 Nucleotides/ribosome
Organism Fruit fly Drosophila melanogaster
Reference Qin X, Ahn S, Speed TP, Rubin GM. Global analyses of mRNA translational control during early Drosophila embryogenesis. Genome Biol. 2007 8(4):R63.PubMed ID17448252
Method Researchers analyzed the translational status of transcripts during early embryogenesis in a genome-wide approach
Comments Researchers estimate the average spacing of ribosomes on the majority of transcripts in Drosophila embryos to be about 30-32 amino acid codons, giving an average ribosomal density of about 90-100 nucleotides per ribosome. Most mRNAs have a ribosomal density in the range of 25-40 codons per ribosome at all three developmental stages.
