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.

Mkey [24]

FCRL4 is an immuno-regulatory receptor that is usually expressed by memory cells that are located in the lymphoid tissues in a region called the sub-epithelial region. During the time of autoimmune disease responses, the glutathione and the FCRL4 function as pro-inflammatory for t-cells and b-cells respectively.

During gene expression, some of the DNA is copied and transcribed into another form. This smaller segment is made of(1 point)

Answer:

DNA is copied and transcribed into another form. This smaller segment is made of genes.

Explanation:

Cell growth, replication, and cell repair are controlled by genetic material found within DNA molecules. These deoxyribonucleic acids' long-chain helical macromolecules are assembled from complex sequences called nucleotides; strong covalent bonds attach these four monomers (adenine, cytosine, guanine, thymine).

Coding regions of DNA are called genes- they contain specific instructions for the cell. Genes can include multiple nucleotides and even several chromosomes. Gene expression typically includes transcription into RNA, and translation into amino acids/ proteins.
