Mutaciones moleculares o puntuales

Las mutaciones moleculares involucran cambios en los nucleótidos del ADN, afectando la codificación de aminoácidos y la estructura de las proteínas. Existen varios tipos de mutaciones, como las silenciosas, que alteran una base pero no cambian el aminoácido resultante.

Mutaciones moleculares o puntuales

Mutaciones moleculares o puntuales

Type in the name of the multiple-perspectives text.

Example: Bridge to Terabithia by Katherine Paterson

es un cambio en un solo nucleótido o en un número reducido de nucleótidos

Identify an important issue from the text that is being presented from different angles. Type it in.

Example: Jesse's drawing talent.

Expansión por repetición
repeticiones de tripletes o cuatripletes de nucleótidos

pequeñas secuencias de ADN de 3 ó 4 pares de bases que se repiten en serie

Cambio de marco de lectura

Decide on the fourth point of view

Type in the name of the last character whose perspective on the issue you are going to present.

Example: Leslie Burke, Jesse's new next-door neighbor, and best friend.

se da cuando por inserción o pérdida de pares de bases se cambia el marco de lectura

Point of view

Type in a relevant quote that highlights the character's point of view. Try to follow a citation format: author's name, chapter, and page.

Example: I can't get the poetry of the trees,' he said. She nodded. Don't worry,' she said. You will someday. He believed her.' (Paterson, 4. 24)

as bases se leen de tres en tres, esto es, cada tres bases determinan un aminoácido.

How is the viewpoint introduced in the story?

Choose an answer:

First person point of view - using the personal pronouns 'I' or 'we'Second person point of view - using the personal pronoun 'you'Third person point of view - using the third-person pronouns 'he', 'she' and 'they'Omniscient point of view - an all-seeing observer tells the story
Duplicación

Whose character does the third point of view belong to?

Type in his/her name.

Example: Mr. Aarons, Jesse's father.

hay un fragmento de ADN que está copiado una o varias veces

What does the character think, say or do that suggests their perspective on the issue?

Type in a quote and try to maintain the citation format.

Example: 'He would like to show his drawings to his dad, but he didn't dare. (...) He'd thought his dad would be pleased. He wasn't. What are they teaching in that damn school? he had asked.' (Paterson, 2.8)

altera la formación de la cadena de aminoácidos y la función de la proteína

What kind of narration introduces the viewpoint?

Choose an answer:

First person point of view - using the personal pronouns 'I' or 'we'Second person point of view - using the personal pronoun 'you'Third person point of view - using the third-person pronouns 'he', 'she' and 'they'Omniscient point of view - an all-seeing observer tells the story
Inserción
se pierde un trozo de ADN alterando la cadena proteica

se puede alterar el marco de lectura para formar la proteína o eliminar aminoácidos que son propios de la cadena proteica

Nonsense mutation

el nuevo triplete que se forma determina la señal de fin de la cadena de aminoácidos

Missense mutation

el triplete codifica para un aminoácido diferente del que debería

en esa posición de la proteína habrá un aminoácido incorrecto

Polimosfirmos

Decide on the second point of view

Name the character (it can either be the main character or one of the supporting characters) whose point of view you are presenting.

Example:
Miss Edmunds, Jesse's music teacher.

hay un cambio de una de las bases de ADN

Type in a quote that points out the character's position about the issue.

Try to follow a citation format: author's name, chapter, and page.

Example: 'She said he was unusually talented, and she hoped he wouldn't let anything discourage him.' (Paterson, 2. 8)

el triplete de nucleótidos que es una parte se cambia

How is the viewpoint introduced in the story?

Choose an answer:

First person point of viewSecond person point of viewThird person point of viewOmniscient point of view

el aminoácido que entra en el lugar en cuestión resulta tener poco o ningún impacto en la función de la proteína.

Mutaciones silenciosas

Decide on the first point of view you are going to present.

Type in the name of the character (it can either be the main character or one of the supporting characters) whose point of view belongs to.

Example: Jesse Oliver Aarons, Jr., the main character of the novel, a fifth-grader living in a rural Southern area.

hay un cambio en una de las bases del ADN

Type in a relevant quote that highlights the character's point of view towards
es un cambio en un solo nucleótido o en un número reducido de nucleótidos.

Try following a citation format: author's name, chapter, and page.

Example: 'Jesse drew the way some people drank whiskey. (...) Lord, he loved to draw. (...) When he was in first grade, he told his father that he wanted to be an artist when he grew up.' (Paterson, 2. 7)

el triplete de nucleótidos se modifica, pero sigue codificando para el mismo aminoácido

What type of narration introduces the viewpoint?

Choose an answer:

First person point of view - using the personal pronouns 'I' or 'we'Second person point of view - using the personal pronoun 'you'Third person point of view - using the third-person pronouns 'he', 'she' and 'they'Omniscient point of view - an all-seeing observer tells the story
