How Do Cytoplasmic Determinants Affect Cell Differentiation

Cytoplasmic determinants are a type of substances found in the female gametes; they are responsible for the regulation of gene expression in the early development of the embryo. They lead to the differential specialization of blastomere during cleavage.

How do cytoplasmic factors affect cell differentiation?

The cytoplasm influences and controls the behaviour of nuclear genes and the differentiation of the cell. The control may be at the level of transcription of the cell.

What are cytoplasmic determinants quizlet?

Cytoplasmic determinants. -maternal substances in the egg that influence course of early development. -after fertilization, early mitotic divisions spread zygote's cytoplasm into separate cells.

Are cytoplasmic determinants proteins?

The factors responsible for this early mapping out, within zygotes, of subsequent cell fate determination are termed cytoplasmic determinants. They consist, for example, of stored mRNAs as well as proteins and various regulatory factors that found within the cytoplasm of the egg cell.

How is cell determination and cell differentiation related to changes in gene expression?

Each differentiated cell type has a specific gene expression pattern that it maintains stably. The genes expressed in a cell type specify proteins and functional RNAs needed by that particular cell type, giving it the right structure and function to do its job.

What are two factors that affect cell differentiation?

The two factors that affect how cells differentiation is distance and energy.

What is an example of cell differentiation?

It is the process in which a cell changes into another cell type. ... An example of cell differentiation is the development of a single-celled zygote into a multicellular embryo that further develops into a more complex multisystem of distinct cell types of a fetus.

What is the role of cytoplasmic determinants?

Unsourced material may be challenged and removed. Cytoplasmic determinants are special molecules which play a very important role during oocyte maturation, in the female's ovary. ... Thus, all the organs of the future embryo are distributed and operating well thanks to the right position of the cytoplasmic determinants.

What are inductive signals?

Synonyms: inductive cell-cell signalling. Definition: Signaling at short range between cells of different ancestry and developmental potential that results in one cell or group of cells effecting a developmental change in the other.

Which of the following would you expect to find as part of a receptor protein that binds with a steroid hormone?

Terms in this set (25) Which of the following would you expect to find as part of the receptor for a steroid hormone? A domain that binds to DNA and domains that bind proteins.

Where are cytoplasmic determinants found?

Cytoplasmic determinants are also found in some post-embryonic cells, where they produce cytoplasmic asymmetry (q.v.). In dividing cells, this leads to asymmetric cell division in which each of the daughter cells differentiates into a different cell type.

What are morphogenetic determinants?

In these embryos, morphogenetic determinants (certain proteins or messenger RNAs) are placed in different regions of the egg cytoplasm and are apportioned to the different cells as the embryo divides. These morphogenetic determinants specify the cell type.

What does morphogenesis mean?

Morphogenesis, the shaping of an organism by embryological processes of differentiation of cells, tissues, and organs and the development of organ systems according to the genetic “blueprint” of the potential organism and environmental conditions.
