No basal lamina is found between the cells of the:

Median rhomboid glossitis is:

Hertwig’s root sheath consists of:

All of the following is the ectodermal in origin, except:

Odontogenesis of the primary dentition begins between:

Histological changes occurring during the eruptive phase:

The caries, all are true except:

Streptococcus mutans is considered to be a principal etiologic agent of caries because it produces acid and it:

The down growth of an epithelial thickening buccal to the dental lamina is known as:

The vestibular lamina gives rise to:

Initiation of caries by Streptococcus mutans is by the production of the:

During the pre-eruptive phase of tooth eruption:

In the post-eruptive phase, a tooth undergoes primarily:

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:

Initiation of dental caries depends on:

The probable reasons for a high incidence of dental caries in the teenage population relates most directly to:

The malleus of inner ear originates from:

Concerning cleft lips and cleft palates:

Fluorosis is caused by:

First stage of deglutition is:

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

Concerning teratogens and their effect on fetal development:

The palate is derived from three primordia:

Branchial arches sharing in tongue development are:

The 3 stages of Deglutition are:

Concrescence usually occurs with:

The reduced enamel epithelium is derived from:

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

One of the following indicates the major components of a tooth germ:

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

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

The first differentiation event in humans occurs at approximately —— days of development, when an outer layer of cells committed to becoming part of the placenta (the trophectoderm) separates from the inner cell mass (ICM). ?

How many protein structure were classified?

Growth factors and their receptors can be grouped into ‘families,’ based upon shared features of ?

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

A protein that works with transcription factors to increase the rate of gene transcription?

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 is the outcome of regeneration?

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

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

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.?

Chromatin immunoprecipitation (ChIP) is a type of immunoprecipitation experimental technique used to investigate the interaction between?

iPSc provided unlimited supplies of ________ cells could be used to generate transplants without the risk of immune rejection.?

An undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.?

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.?

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

What are the criteria for achieving to generate iPSc?
