Chapter 43.4, Problem 1CYL
Summary Introduction
To explain:
The roles of gene regulating substances in the egg cytoplasm, transcription factors and induction between cells in development.
Introduction:
Fertilization is a process in which haploid male gamete (sperm) fuses with the haploid female gamete (egg or ovum) that result in the formation of diploid zygote. The zygote then further develops into an embryo. During the developmental process, the cytoplasm of an egg contains certain gene regulating substances, such as transcription factors which transcribe and translate those genes which involved in development of an embryo.
