TASK 1:
Question: The diagram shows the process by which sheep embryos are cloned.
ANSWER:
The diagram illustrates the process by which sheep embryos are cloned using genetic material from two different sheep.
Overall, the procedure involves several biological stages, beginning with the extraction of DNA from a body cell and ending with the birth of a cloned lamb that is genetically identical to the original sheep.
Initially, a body cell is taken from Sheep A, from which its DNA is carefully extracted. At the same time, an egg cell is removed from Sheep B, and the nucleus of this egg cell is eliminated to remove its original genetic information. Following this, the DNA obtained from Sheep A is fused with the empty egg cell taken from Sheep B, creating a combined cell containing Sheep A’s genetic material.
In the next stage, the fused cell begins to divide and develops into an embryo. This embryo is then implanted into the uterus of a foster mother, referred to as Sheep C. After a normal period of gestation, the foster mother gives birth to a lamb that is a clone of Sheep A, as it carries the same genetic characteristics.
