The dental lamina:

The following are all derived from the stomodeal ectoderm such as:

The reduced enamel epithelium is derived from:

Advanced bell stage of tooth development refers to:

The nerve of the third branchial arch is:

One of the following is associated with an erupted tooth:

Turbid dentin in carious tooth is all except:

A layer of cells that seems to be essential to enamel formation but do actually secrete the enamel except:

The epithelial rests in the periodontal ligament are derived from:

The primary cause of periodontal disease is:

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

One of the following does contribute to the formation of the upper lip:

An oblique facial cleft is formed when the:

The stratum intermedium:

Enamel pearls occur in:

The number of baby teeth is:

The map of taste buds for:

The taste sensations appear to be located from the parts of:

The cap stage occurs between the:

Pharyngeal mucosa is innervated by the glossopharyngeal nerves because it develops from the:

Dental lamina is formed when:

Neural crest cells are a temporary group of cells unique to vertebrates that arise from the embryonic ectoderm cell layer, and in turn give rise to A diverse cell lineage including:

In a developing tooth, if Hertwig’s sheath and the epithelial diaphragm were failed to form, the resulting tooth would exhibit:

The medial pterygoid follows the same angle as masseter arising from the medial pterygoid plate, where does it attach on the mandible at:

The three major salivary glands are:

All of the following does occur during the eruptive phase, except:

The following organisms is found in deep carious lesions rather than in incipient lesions is:

The most likely factor responsible for tooth eruption is:

The following is component of the enamel organ except:

The dental sac plays an important role in the formation of all of the following except:

The cranial nerve supplies to muscles of mastication is:

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.?

Transcription can be divided into 3 stages: initiation, elongation, and termination, each regulated by a large number of proteins such as transcription 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.?

How many types of intra oral tissue?

Protein synthesis consist of 2 steps. What are they, and where do they take place?

There are two major factors influence repair and regeneration?

What is the hierarchy of embryonic stem cells?

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.?

All four factors are absolutely necessary. In particular, the gene c-Myc is known to promote tumor growth in some cases, which would not affect iPSC usefulness in transplantation therapies. ?

Event during or following protein translation ?

Periodontium which includes?

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

Repression, or suppression – decrease the rate of gene transcription?

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

Growth factor is sometimes used interchangeably among scientists with the term cytokine.?

iPSc were generated by:?

Cytokines are a broad and loose category of long big proteins (~5–20 kDa) that are important in cell signalling.?

iPSCs were reprogrammed to an embryonic stem cell-like state by introducing genes important for maintaining the essential properties of embryonic stem cells (ESCs). ?

What are the gold standard transcription factors using for generating iPSc?

What is the outcome of regeneration?

What is the outcome of repair?

A protein that binds to DNA and regulates gene expression by promoting or suppressing transcription?

The process of making messenger RNA (mRNA) from a DNA template by RNA polymerase?

Embryonic stem cells are derived from embryos at a developmental stage before the time that implantation would normally occur in the uterus. Normally, it takes about 10 days.?

Work flow of generating iPSc?

Mesenchymal stem cells can be extract from many types of tissue, but the most commence one is bone marrow.?

Retroviruses used to deliver the four transcription factors in the earliest studies is safe to generating iPSCs.?
