Lee la siguiente situación, y diseña un experimento. (No tienes que realizarlo)
Lynna [10]

Answer:

- Luis quiere saber si los cristales de yodo pueden disuelverse en distintos líquidos  

- Luis necesita cristales de yodo, agua, alcohol y aceite mineral

- La hipótesis de trabajo puede ser: "los cristales de yodo se disuelven en distintos líquidos", con lo cual la hipótesis alternativa indicaría que los cristales de iodo no se disuelven

- La recopilación de los datos puede consistir en la realización de tres experimentos en los cuales los cristales de yodo son sumergidos en agua (1° experimento), alcohol (2° experimento) y aceite (3° experimento).  

Explanation:

En el método científico, la pregunta científica refiere a una cuestión particular la cual es planteada con el objetivo de responder algún aspecto particular del mundo real. A partir del planteamiento de una pregunta científica es posible formular dos hipotésis denominadas hipotésis nula e hipótesis alternativa, las cuales representan supocisiones contrapuestas que permiten contestar dicha cuestión. Subsecuentemente, los científicos realizan experimentos y/o observaciones que permiten recopilar datos cuyos resultados son utilizados para confirmar (o rechazar) la hipótesis nula. Por otra parte, es necesario resaltar que durante el proceso de experimentación se requiere de la utilización de controles positivos y negativos que permitirán corroborar si dichos experimentos fueron realizados correctamente.

A mutation occurs in which a base (T) is inserted into the DNA sequence after the G, at the position marked with an asterisk, be
Zarrin [17]

A mutation which occurs when a base is introduced into the DNA sequence before transcription begins will lead to frame-shift of a single base on the DNA sequence resulting in nonfunctional protein from the transcribed mRNA.

Explanation:

This change either through addition or deletion of a single base in the codon sequences of the DNA will modify the amino acid codes and will result in nonfunctional proteins after transcription.

This mutation will just result in change of a single base, i.e., it would be added either to the enhancer region or the silencer region of the sequence before the promoter which initiates transcription.

The mRNA produced due to mutated DNA sequence after the deletion or insertion point will be read as out of frame thus resulting in nonsense protein.
