Use the figure to answer the following question. Which of the following enzymes was used to produce the molecule of DNA in the figure?

How can a gene that contains introns be made shorter (but remain functional)for genetic engineering purposes?

Why is it so important to be able to amplify DNA fragments when studying genes?

In recent times, it has been shown that adult cells can be induced to become pluripotent stem cells (iPS). To make this conversion, what has been done to the adult cells?

Why are yeast cells frequently used as hosts for cloning?

In large scale, genome-wide association studies in humans, what types of genetic markers do researchers look for?

The first cloned cat, called Carbon Copy, was a calico, but she looked significantly different from her female parent. Why was this the case with this clone?

Which of the following statements correctly describes one characteristic of genetically engineered plants?
