Title: The nematode Caenorhabditis elegans Post by: ppk on May 23, 2011 The nematode Caenorhabditis elegans
A) has only a single chromosome, which has been fully sequenced. B) has about 1,000 genes, each of which has been fully sequenced. C) is composed of about 1,000 cells, in which the developmental origin of each cell has been mapped. D) uniquely, among animals, utilizes programmed cell death during normal development. E) is composed of a single cell, in which the developmental origin of each protein has been mapped. Use the following information to answer the next few questions. In a study of the development of frog embryos, researchers stained several early gastrulas with vital dyes and noted the locations of the dyes after gastrulation. The results are shown in the following table.
