Sustancia formada por ADN y proteínas histonas que integra los cromosomas

Answer:

La cromatina

Explanation:

La cromatina es una sustancia dentro de un cromosoma que consta de ADN y proteína. El ADN lleva las instrucciones genéticas de la célula. Las principales proteínas de la cromatina son las histonas, que ayudan a empaquetar el ADN en una forma compacta que encaja en el núcleo celular.

La cromatina es un complejo altamente organizado de ADN y proteínas y es un componente principal del núcleo celular. Las proteínas histonas ayudan a organizar el ADN en unidades estructurales llamadas nucleosomas, que luego se ensamblan en una estructura compacta (cromatina) y, finalmente, en estructuras muy grandes de orden superior (cromosomas).

exis [7]

Answer:

It requires energy

Explanation:

In the coupled transport system, coupled carriers couple the inward transport of one solute across the membrane to the outward transport of other solutes across the membrane. The tight bonding that occurs between the transport of two solutes allows these carriers to utilize the energy stored in one solute, usually an ion, to facilitate transport of the other. With this way, the free energy released during the movement of an ion down an electrochemical gradient is utilized as the driving force to transport other solutes inwards, against their electrochemical gradient.
