Reproductive cloning of human embryos is generally considered unethical. However, on the subject of therapeutic cloning, there i
s a wider divergence of opinion. Which of the following statements provides a likely explanation? A) A clone that lives until the blastocyst stage does not yet have human DNA.
B) The use of adult stem cells is likely to produce more cell types than the use of embryonic stem cells.
C) Cloning to produce stem cells relies on a different initial procedure than reproductive cloning.
D) Cloning to produce embryonic stem cells may lead to great medical benefits for many.
D) Cloning to produce embryonic stem cells may lead to great medical benefits for many.
Explanation:
stem cells are considered as the greatest hope in medicine. Research in embryonic stem cells leads to effective and new treatment in many human diseases
In many countries the reproductive cloning in humans is totally illegal and unethical.
while in therapeutic cloning the blastocyst is not transferred to a womb instead, embryonic stem cells are isolated from the cloned blastocyst and are genetically matched to the donor organism.
therapeutic cloning also helped in the research and production of cells genetically identical to the patient.
The answer for this question would be the second option. Genomic studies cover the analysis of the changes of genome by scanning the markers across complete sets of DNA. Based on these studies, the change in gene sequences happen that resulted to a change in the way that the brain interprets speech in between 4 and 9 million years ago.
