The type of cloning known as somatic cell nuclear transfer (SCNT) has been a game-changer in animal reproduction. In this process, the nucleus of a somatic cell is transferred into an egg cell from which the nucleus has been removed. This technique not only paved the way for cloning famous animals like Dolly the sheep but is also used in livestock breeding to produce high-quality embryos that can be implanted into recipient cows. During pregnancy, the critical phase characterized by the differentiation of cells into distinct tissues, organs, and systems is called organogenesis. This stage typically occurs between the third and eighth weeks of gestation and is foundational for forming the complex structures that will function in the developing organism. It's a fascinating and delicate time when a single fertilized egg transforms into a multicellular marvel!
