Answer:
The stem cells possess two cardinal characteristics, that is, self-renewal and differentiation. The examples are embryonic stem cells and hematopoietic stem cells. The genetically determined immunodeficiency in a person is generally a result of the defective gene in the hematopoietic stem cells that produce red blood cells, white blood cells, and other components of blood.
The examples of genetically determined immunodeficiency diseases are SCID, X-linked Agammaglobulinemia, and others. The individual suffering from genetically determined immunodeficiency exhibits a defective gene in hematopoietic stem cells. There are two methods of treatment, that is, stem cell therapy and gene therapy.
The procedure of stem cell transplantation generally comprises HLA matching, in which the main step is to prevent graft rejection. It is succeeded by harvesting of hematopoietic stem cells from the HLA matched donor. The step of conditioning is performed to eradicate the recipient HSCs by radiotherapy and chemotherapy succeeded by the transfer of harvested donor HSCs to the patient or the recipient.
A person cannot receive his own stem cells as his or her each and every cell is defective in that specific gene accountable for the disease.
1. The four primary functions of carbohydrates in the body are to provide energy, store energy, build macromolecules, and spare protein and fat for other uses.
2. Glucose energy is stored as glycogen, with the majority of it in the muscle and liver.
Examples:
1. Beans and legumes, such as black beans, chickpeas, lentils and kidney beans.
2. Fruits, such as apples, berries and melons.
3. Whole-grain products, such as brown rice, oatmeal and whole-wheat bread and pasta.
4. Vegetables, such as corn, lima beans, peas and potatoes.
Numerous catabolic operons have their transcription controlled by glucose. The three enzymes needed for conversion are encoded by the operon's five structural genes.
<h3>How many genes are there in an operon?</h3>
Operons have a transcription promoter at the beginning, two to twelve genes on average, and a transcription terminator at the conclusion (Zheng et al. 2002; Lawrence 2003).
<h3>Yes, there is just one promoter for operons.</h3>
An operon is a group of genes that all use the same transcriptional promoter. Every operon contains regulatory DNA sequences that act as binding sites for regulatory proteins that either promote or inhibit transcription.
<h3>The promoter is a 3 or a 5?</h3>
An area of DNA known as a promoter is where RNA polymerase starts to transcribe a gene. Promoter sequences are often found directly in the genome.
