I suppose the yellow peg is facing the green peg, in which case the green peg must be guanine.

The bases are associated in pairs. In each pair there is always a purine associated with a pyrimidine. The association is by weak bonds: the hydrogen bonds, two bonds for an AT pair; three links for a GC pair. When we know the sequence of one strand we can deduce the sequence of the other strand. The two strands are oriented opposite to the 3 'and 5' ends (the strands are called antiparallel).

Number the following steps in the correct order and tell which stage it occurs in:
Sedaia [141]

Answer:

The correct answer is given below:

Explanation:

1. A cleavage furrow or cell plate forms, separating the nuclei - Cytokinesis.  During cell division, after division of nucleus, cytoplasm divides by furrow in an animal cells and by cell plate formation in the plant cells.

2. Chromosomes line up at the equator and chromatids are attached to spindle fibres—Metaphase. During metaphase all the chromosomes get arranged on the equatorial plane or the central plane

3. Nuclear membrane and nucleolus reappear- Telophase. The nuclear membrane starts to form around each of the daughter chromosomes and nucleolus also reappears in the daughter nuclei.

4. Genetic material replicates and is joined at the centromere- S-phase of the interphase. Duplication or copying of the DNA occurs in this phase  

5. Centromeres divide and single-stranded chromosomes move to the poles- Anaphase.  During anaphase, the sister chromatids of each chromosome gets separated and move to the opposite poles.

- ¿Qué ruta sigue cada uno DE LOS TRIGLICERIDOS en su afán de obtener energía?… ¡sí, energía llamada ATP! - Ruta metabólica que
Fed [463]

Answer:

Los trigliceridos antes de ser disociados en moleculas energeticas necesitan ser absorvidos.

Para eso es importante aclarar que se absorbe nen elintestino en forma de quilomicron, por su caracteristica hidrofuga y son emulsionados por el jugo pancreatico y los jugos provenientes de la vesicula.

Una vez absorbido, este puede seguir diferentes rutas metabolicas de un cuerdo a la necesidad energetica de la persona.

En el caso que una persona obtiene energía de un acido graso o de su reserva adiposa es por que no hay mas reserva de glucogeno, es decir en ayunos prolongados, en personas con dificultad de asimulacion glucosidica como los diabeticos, personas con trastornos anorexicos recientes.

Explanation:

Las grasas contienen una gran aporte de ATP posterior a la adicion de CO2 y H20, en los procesos de beta oxidacion y el ciclo del acido citrico.

El metabolismo de estos se considera toxico en momentos prolongados ya que el  producto de su metabolizacion son los cuerpos cetonicos. Los cuerpos cetonicos aumentan la cetoacidosis de la sangre y atraviezan la barrera hematoencefalica.

El ph por la cetoacidosis disminuye generando toxicidad tisular y del snc, hiperventilacion, hipercapnia, cansancio, aliento cetonico, fallo proteico de algunos complejos enzimaticos de nuestro organismo.

Ademas esimportante aclarar que el ser humano obtiene carbohidratos del glicerol y no de la porcion de acidos grasos.
