Summary Introduction

To review:

One of the techniques to show that nurse cells can transfer the maternal effect genes (gene B) to the oocyte.

Introduction:

Maternal effect genes are those genes from the mother's genome whose RNA (ribonucleic acid) and protein are accumulated in the zygote even before the expression of zygotic genes. The expression of this gene is not at all affected by the zygote. Northern and western blotting techniques are used to detect the specific RNA and protein fragments that are separated via the gel electrophoresis.
