Chapter 7, Problem 11WIO
Summary Introduction
To determine:
The ways by which a roundworm cell is able to silence the unneeded genes.
Introduction:
Gene silencing is a mechanism of reducing the expression of a particular gene. It can be done either during transcription or translation. Caenorhabditis elegans consists of 556 cells at the time of hatching, but each cell expresses only a subset of the genes, and they become specialized only in a particular function.
