Determination. (Science: cell biology)
The committment of a cell to a particular path of differentiation
, even though there may be no morphological features that reveal this determination.
What is the definition of determination in biology?
In biology, determination is
the process of matching a specimen of an organism to a known taxon, for example identifying a plant
. The term is also used in cellular biology, where it means the act of the differentiation stem cells becoming fixed.
What is determination in developmental biology?
Cell determination is
the process by which the cell commits to a certain developmental pathway and eventually produces a specialized cell
. Cell determination usually takes place as a result of inductive signaling between nearby cells. There are three different mechanisms by which inductive signaling can take place.
What is genetic determination?
Sex determination,
the establishment of the sex of an organism
, usually by the inheritance at the time of fertilization of certain genes commonly localized on a particular chromosome.
What does determination mean example?
Determination is defined as a firm intent or a decision which has been reached. An example of determination is
the strength to keep applying for jobs after being turned down by dozens of
potential employers. An example of determination is a jury’s verdict in a trial. noun.
How is cell determination?
The process in which a previously undifferentiated cell is already programmed to become a specific cell type by following a specified path towards cell differentiation. Cell determination is
influenced by the action of the extracellular environment and the contents of the cell’s genome
.
How are pattern formed?
Pattern formation is
the developmental process by which cells acquire different identities
, depending on their relative spatial positions within the embryo. Pattern formation ensures that tissues and organs develop in the correct place and orientation within the body.
What’s the difference between determination and differentiation?
The main difference between cell determination and cell differentiation is that
the cell determination is the assignment of the fate of the cells
whereas, the cell differentiation is the morphological modification of the cells to perform the assigned function.
What comes first cell determination and differentiation?
Primary Factors Influencing Cell Differentiation
Gene Structure
– This is the most important factor when it comes to cell differentiation. Each of the viable genes contains important information that determine the cell type and physical attributes of the animal (host).
Does differentiation or determination happen first?
Explanation: Once a committed cell begins to develop specialized functions, it is known as
differentiation
. Before a cell differentiates, it makes a commitment to a certain cell type, first by specification, which is reversible, and then by determination, which is irreversible.
What are XY females?
XY gonadal dysgenesis, also known as
Swyer syndrome
, is a type of hypogonadism in a person whose karyotype is 46,XY. Though they typically have normal female external genitalia, the person has functionless gonads, fibrous tissue termed “streak gonads”, and if left untreated, will not experience puberty.
Which parent determines the gender of the child?
Gender is Determined by
the Father
. Because sperm cells can carry either of the two sex chromosomes, it’s the male who technically determines the baby’s gender.
Who is responsible for male or female child?
Men determine
the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother’s X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother’s to make a boy (XY).
What are the types of determination?
The four basic types of nominal determination are
singular definite, indefinite
(a variety of determinations including simple indefinite), absolute and relative, where possessive determination is a combination of relative reference and possessor specification.
What type of word is determination?
Determination is a
noun
– Word Type.
What do you mean by determination answer?
Determination is
the quality that you show when you have decided to do something and you will not let anything stop you
.
