NIVELES DE ORGANIZACIÓN CELULAR

Conflict is present everywhere in the world around us. We experience conflict on a daily basis, and it can be minor or major.

Conflict in a story is a struggle between opposing forces. Characters must act to confront those forces and there is where conflict is born. If there is nothing to overcome, there is no story. Conflict in a story creates and drives the plot forward.

Cromosomas

In this type of conflict, a character must take on society itself, and not a single person. The character stands at odds with societal norms and realizes the necessity to work against these norms. This is an external conflict.

Mitosis

Es el tipo de división celular que utilizan todas las células de nuestro organismo, a excepción de las células situadas en el ovario y en el testículo

Meiosis

División celular que utilizan las células que forman parte del ovario y del testículo, denominadas células germinales.

Los cromosomas tienen tres sitios específicos de particular importancia.

El lugar donde se anclan los microtúbulos del huso acromático durante la mitosis y la meiosis.

El centrómero o constricción primaria

Se encuentran en el interior de la célula eucariota

Give examples of man versus society conflict in the real world.

Formados por DNA unido a proteínas, en especial a histonas.

Give examples of man versus society conflict in a literary work.

Collar de perlas

This situation results from a protagonist working against what has been foretold for that person. While this conflict was more prevalent in stories where gods could control fate, such as in ancient Greek dramas, there are still examples of this type of conflict in more contemporary literature.

Esta formado por:

Since in real life we can't say that such examples of man versus supernatural, there are some superstitions that can influence a person's life.

Give examples of these superstitions.

Proteínas de histonas y de bases nitrogenadas de ADN.

Hebra de cromatina (ADN con nucleosomas, conformados por histonas, "cuenta de collar").

Give examples of man versus fate conflict in a literary work.

Al conjunto de estructuras se le llamas:

Fibra de cromatina, Tiene un aspecto repetitivo en forma de collar de perlas, donde las perlas serían los nucleosomas, unidos por los linker.

Solenoides

A more contemporary type of conflict, this situation results from humans involved in a struggle with man-made machines. This is an external conflict.

Se refiere a la estructura cuaternaria de los niveles de estructuras del ADN que consiste en el enrollamiento de un conjunto de nucleosomas.

Give examples of man versus machine conflict in a literary work.

Cromatinas

This conflict develops from a protagonist’s inner struggles and may depend on a character trying to decide between good and evil or overcoming self-doubt. This conflict has both internal and external aspects, as obstacles outside the protagonist's force them to deal with inner issues.

Consiste en la combinación de ADN con proteínas.

Give examples of man versus self conflict in a literary work.

Nucleosoma

In this type of conflict, a character is tormented by natural forces such as storms or animals. This is also an external conflict.

Formado por 146 pb de ADN enrolladas alrededor de un octámero de proteínas histonas

Give examples of man versus nature conflict in the real world.

Están formados por proteínas de histonas y de bases nitrogenadas de ADN.

Give examples of man versus nature conflict in a literary work.

¿Que es el DNA?

A situation in which two characters have opposing desires or interests. The typical scenario is a conflict between the protagonist and antagonist. This is an external conflict.

Asas de DNA

El nucleosoma esta formado por un octámero de hisomas

Esta estructura vista al microscopio se ve como si fuera un collar de perlas del que las cuentas son los nucleosomas.

¿Que contiene?

Adenina (a) (G) de la guanina Citosina (c) Tiamina (t)

¿Donde se encuentra?

Give examples of man versus man conflict in the real world.

La mayor parte de la DNA se coloca dentro del núcleo y se llama DNA nuclear.

La DNA es ácido desoxirribonucléico. Está situada en los núcleos de las células, que componen la carrocería.

Give examples of man versus man conflict in a literary work.
