The tooth in permanent dentition is the most susceptible to dental caries is:

Deglutition is the complex process that:

The lateral spread of dental caries is facilitated mostly by the:

Chemico-parasitic theory of dental caries is proposed by:

Functions of the digestive system are:

Component of mastication are:

The malleus of inner ear originates from:

Median rhomboid glossitis is:

The stratum intermedium:

Taste bud is:

The palatal shelves:

Concrescence usually occurs with:

Inner enamel epithelium:

The cap stage occurs between the:

During tooth eruption, the permanent successors of the primary teeth move occlusal and:

All of the following is true of parotid glands, except:

The inferior parathyroid gland originates from:

Four basic qualities:

The cell rests of Malassez are derivatives of:

Regarding deglutition:

Second stage of deglutition is:

Hertwig’s root sheath consists of:

Miller put forth the acidogenic theory of dental caries in the year:

Why embryonic stem cells were banned for basic research?

Why transcription factors is the most import key to generate iPSc, cell reprogramming?

If the ICM, inner cell mass, is removed from its normal embryonic environment and cultured under appropriate conditions, the ICM-derived cells can ——————————————- indefinitely and still maintain the developmental potential to form any cell type of the body?

Work flow of generating iPSc?

In transcription an mRNA chain is generated, with both strands of the DNA double helix in the genome as a template.?

Transcription factor is a protein that controls the rate of transcription of genetic information from messenger RNA to DNA, by binding to a specific ribosomes.?

In our blood, there is a small amount of stem cells which are ready to be differentiate to any cell type under the control of growth factors.?

iPSc were generated by:?

Growth factors are proteins that regulate many aspects of cellular function, including survival, proliferation, migration and differentiation.?

Stem cell hierarchy from top to bottom?

Some important human diseases are caused by the death or dysfunction of one or a few cell types, e.g., insulin-producing cells in diabetes or dopaminergic neurons in Parkinson’s disease. Therefore, understanding and using stem cells as tool to study this disease model provide a better understand this dysfunction of cell types.?

How many protein structure were classified?

What is Yamanaka’s factors?

Ethical issues associated with the production of ESCs do apply to iPSCs, which offer a controversial strategy to generate patient-specific stem cell lines.?

What are the 4 steps of responses of mucosa to damage?

A,growth factor is a naturally occurring substance capable of stimulating cellular growth, proliferation, healing, and cellular differentiation. Usually it is a protein or a steroid hormone.?

A growth factor is a naturally occurring substance capable of stimulating cellular growth, proliferation, healing, and cellular differentiation.?

What do Growth Factors Do?

In the future, possible dentist can use dental pulp stem cells, 3rd mandibular molar, in cell bank due to their pluri-potent.?

What are the function of transcription factors?

Growth factor responsible for repair and regeneration: VEGF, Vascular endothelial growth factor?

The ICM, inner cell mass, cells have the potential to generate any cell type of the body, after implantation, they are ————– as they differentiate to other cell types with more limited developmental potential. ?

Yamanaka’s factors were used to generating iPSc in 1st generation because:?

Transcription factors is a protein that control the rate of transcription of genetic information from?

Controlling the rate of gene transcription for example by helping or hindering RNA polymerase binding to DNA?
