Answer:
tres puentes de hidrógeno
Explanation:
El acido desoxirribonucleico (ADN) es una molécula compuesta por dos hélices antiparalelas las cuales interaccionan entre sí a través de puentes de hidrógeno entre bases nitrogenadas. Existen dos clases de bases nitrogenadas: 1-purinas (Guaninas y Adeninas) y 2-pirimidinas (Timina y Citosina). En la doble hélice, la Adenina (A) siempre aparea con Timina (T) a través de dos puentes de hidrógeno, mientras que la Citosina (C) siempre interactúa con Guanina (G) a través de tres puentes de hidrógeno, es decir un enlace de hidrógeno más por cada par de bases. Es por esta razón que una molécula de ADN con alto contenido GC es más estable y por lo tanto tiene una temperatura de desnaturalización mayor.

Variables. An experiment generally tests how one variable is affected by another. The affected variable is called the dependent variable.
Certain medication could cause the blood vessels in your eyes to dilate. Also lack of sleep and sleeping on your stomach can also cause this. <span />
E. coli are a species of bacteria. Like all bacteria, they have a round piece of DNA that contains most of their genetic information, but also plasmids, that contain some more. Plasmid can be passed on from bacterium to bacterium and they contain information for fighting antibiotics. Tetracycline is such an antibiotic. The process of putting a plasmid inside a bacterium is called transformation. So what the above sentence really says, is that a bacterium just got a plasmid that is probably holding the genetic information to produce proteins that fight antibiotics like tetracycline. While regular strains of E. coli might not be able to deal with tetracycline, transformed strains will probably be able to survive it. Hence, the culture will have live bacteria and the bacteria that have a plasmid against tetracycline will be favored and survive.
