Abstract

This study reports the cloning, characterization and identification of a previously undetected ribosomal RNA in Drosophila melanogaster. The ribosomal RNA is 370 nucleotides in length and contains the 5.8S and 2S ribosomal RNA coding regions. Analysis of polysome-containing cell extracts indicates that the RNA is present on polysomes suggesting a functional role within the ribosome. Northern blot analysis indicates that the RNA is also present in adult Drosophila melanogaster flies.

摘要

本研究报告了在黑腹果蝇中克隆、表征和鉴定一种先前未检测到的核糖体RNA。该核糖体RNA长度为370个核苷酸，包含5.8S和2S核糖体RNA编码区域。对含有多核糖体的细胞提取物的分析表明，该RNA存在于多核糖体上，表明其在核糖体中具有功能作用。Northern印迹分析表明，该RNA也存在于成年黑腹果蝇中。
