All cells come from preexisting cells. A cell divides its DNA in a process known as mitosis and its cytoplasmic contents in a process known as cytokinesis, producing two new daughter cells while all life begins as a single cell, the human body is not just one cell type. Cells that can divide without becoming a specific cell type (i.e. skin cells) are known as stem cells. When stem cells undergo mitosis and divide, they produce two cells. One cell remains a stem cell and the other is a partially specialized cell known as a progenitor cell. Cells undergo a process of specialization or determination called differentiation to become neurons, muscle cells, or skin cells. Stem cells are the source of all different cell types.
Thyroid hormones diffuse through the plasma and enter the cell nucleus. The hormone will then bind to specific receptors for the hormone inn the nucleus forming a thyroid hormone receptor complex. This action later binds to specific regions of the DNA known as responsive element which results in increase in transcription of certain genes . Every binding is unique in the way they form and bind. An increase in gene transcription means an increase in amount of mRNA.
