Q: What is a standard supply of donor cells in therapeutic cloning experiments?

Therapeutic cloning entails making a cloned embryo for the only function of manufacturing embryonic stem cells with the identical DNA because the donor cell. The richest supply of embryonic stem cells is tissue shaped throughout the first 5 days after a fertilised egg has began to divide. At this stage of improvement, the clump of cells are known as the blastocyst.

 Blastocyst

Epithelial cells

Astrocytes

Osteocytes

A: 1
