Final answer:
Embryonic stem cells are pluripotent cells that have the ability to differentiate into any type of human tissue. They originate from totipotent cells from the zygote. Their chromatin is mostly euchromatin, allowing them access to the transcription machinery of the cell and making diverse differentiation possible.
Option B
Step-by-step explanation:
The question pertains to the nature of embryonic stem cells which are fundamentally known as pluripotent because they possess the ability to differentiate into any type of human tissue.
Embryonic stem cells originate from the division of the zygote, which are considered totipotent as they have the potential to differentiate into any cells necessary for the development of an organism. However, the chromatin of embryonic stem cells is mostly euchromatin (option B).
Euchromatin is a form of chromatin that is lightly packed and readily accessible to the transcription machinery of the cell, which facilitates their capability for diverse differentiation. This is crucial for the function of pluripotent stem cells, allowing them to differentiate into various cell types.
