Question

Specialization in structure and function of cells is caused by a differential expression of genes. This means that certain genes are turned on or off in different cells, leading to the development of specialized structures and functions. Inhibition of transcription would prevent any genes from being expressed, while methylation of nucleotides can affect gene expression but alone is not sufficient for the development of specialized cells. Translation without transcription is not possible as transcription is necessary for the production of RNA, which then undergoes translation.
