WebCpA has been shown to be a vital part in controlling gene expression by affecting the RNA's lifespan, regulating its stability, translational efficiency, and export from the nucleus. As the presence/absence of a poly (A) regulates these processes, the length of a poly (A) tail can itself be regulated for the same purposes. In embryology, cleavage is the division of cells in the early development of the embryo, following fertilization. The zygotes of many species undergo rapid cell cycles with no significant overall growth, producing a cluster of cells the same size as the original zygote. The different cells derived from cleavage are called blastomeres and form a compact mass called the morula. Cleavage ends with the formation of the blastula, or of the blastocyst in mammals. black portugal tourWebJul 1, 2002 · This approach promises to permit generation of directed mutations in many types of cells and organisms.

Most insect eggs undergo superficial cleavage, wherein a large mass of centrally located yolk confines cleavage to the cytoplasmic rim of the egg. One of the fascinating features of this cleavage type is that cells do not form until after the nuclei have divided. Cleavage in a Drosophila egg is shown in Figure 9.1. The zygote nucleus ...
