Answer:
The correct option is D. The nerve and red blood cells will turn on and off different portions of their DNA, using different genes to make different proteins.
Explanation:
A zygote is totipotent which means it has the ability to differentiate into any cell type found in the body along with the placental cells.
The nerve and red blood cells are specialized cells and they cannot differentiate into any other cell type.
All cells in the body are formed from the zygote. All the cells in the body have the same chromosomes and the same genes. However, these cells become specialized because certain part of the DNA is activated in one type of cell which helps it perform its function. Different genes are activated in different specialized cells which are able to transcribe and translate.
After a steroid hormone binds to its intracellular receptor, transcription of specific genes occurs. The activated receptor moves into the nucleus and binds to DNA
<h3>What is steroid hormone and intracellular receptor ?</h3>
Target cells have steroid hormone receptors in their nuclei, cytoplasm, and plasma membranes. They are typically intracellular receptors (often cytoplasmic or nuclear) that start the signalling processes for steroid hormones, which modify the expression of genes over the course of hours to days.
- By attaching to intracellular receptors, steroid hormones control cellular functions by changing the expression of specific nucleotide sequences. Since the majority of steroid receptors in target cells reside in the cytoplasm, they must enter the nucleus to change gene expression.
