Cloning in Animals Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is the first step in the embryo transplant process for cloning animals?

Egg cells from one animal with desirable traits are artificially fertilised with sperm cells from another animal with desirable traits.

What is the purpose of using host mothers in the embryo transplant process?

Host mothers carry the identical embryos to term, giving birth to clones of each other.

What was the first mammal to be cloned using adult-cell cloning?

The first mammal to be cloned was a sheep named Dolly in 1996.

In adult-cell cloning, what is done to the nucleus of the unfertilised egg cell?

The nucleus is removed from the unfertilised egg cell and replaced with the nucleus from a cell of the animal to be cloned.

What stimulates the egg cell to divide and form an embryo in adult-cell cloning?

A small electric shock is administered to the egg cell to stimulate division by mitosis, leading to the formation of an embryo.
