WGU C785 Biochemistry Preassessment Questions and Answers Already Passed

Assuming 100% reaction efficiency, how many DNA copies are created after the completion of four complete PCR cycles? 16 What is the function of DNA polymerase in the process of PCR? It recognizes the primers and uses the available dNTPs to replicate the template DNA sequence. What are possible blood types of the parents of a patient with blood type AB? A and B − Amino Acid Number Tyr Gly Thr Pro − Amino Acid Sequence TAC GGG ACA CCA − DNA Sequence What is the amino acid in position 118 that results from a single nucleotide insertion immediately following the three guanines that encode for glycine 116? Thr In sickle-cell disease, the glutamic acid (Glu) at position number seven is mutated to valine (Val). What change in codons corresponds to this mutation? GAA to GTAWhich type of mammalian DNA damage repair requires the presence of the chromosome that is homologous to the damaged chromosome? Recombination Xeroderma pigmentosum (XP) is a recessive genetic disease that occurs when one or more of the genes that perform nucleotide excision repair are nonfunctional. Why do XP patients have a much higher incidence of skin cancer than the general population? The mutation rate of all other genes is higher due to failure to repair
