You work in a DNA lab and have been doing karyotypes for research on various animal species. Your labeling has fallen off several of your specimens. You think this karyotype is from a human. How do you know?
1.There are 23 different chromosomes (46 chromosomes total), which is characteristic of humans.
2.Humans do not have Y chromosomes.
3.There are two of each chromosome, which is characteristic of humans.
4.There is no way to tell. You need more information to determine if this karyotype is from a human.
Question 2In patients who receive transplants, the recognition protein in the transplanted organ would be different than that of the recipient. What would this mean for the patient?
1.The patient would begin to recognize the new protein as self.
2.The patients immune system would attack and reject the new organ, requiring the patient to take immune suppressing medication.
3.The protein of the transplanted organ must be changed to match that of the patient.
4.The proteins on the surface of the cells from the transplanted organ will modify themselves to more closely resemble those of the patient, so the patients immune system wouldnt reject it.
