Cloning

Question 1

Who are the offspring of a somatic cell nuclear transfer genetically identical to?

Answer 1

They are genetically identical to the donor of the somatic cell

Question 2

Who are the offspring of embryo splitting genetically identical to?

Answer 2

Each other

Question 3

What does SCNT stand for?

Answer 3

Somatic cell nuclear transfer

Question 4

When is embryo splitting beneficial?

Answer 4

When testing medical procedures

Question 5

What is the process of embryo splitting?

Answer 5

Embryo removed from donor, split in the lab and each new embryo is implanted into a surrogate

Question 6

How many donors are there in the an SCNT and what do they each donate?

Answer 6

2 donors, one donates a somatic cell and another donates an egg

Question 7

What would SCNT be used for?

Answer 7

If an adult has favourable traits and are wanted in new offspring

Question 8

Outline the process of SCNT briefly

Answer 8

Two donors donate: one somatic cell and one egg cell, the nucleus of the egg cell is removed and the enucleated cell is fused with the DNA of the somatic cell nucleus. Hormones are added to initiate mitosis and the embryo is implanted in a surrogate
