The correct order of these steps is? 78 98 55 98 78 55 78 55 98 98 55 78 55 78 98 55 98 78 Question 2 Select one answer. 10 points During DNA replication it is possible for the T residue in the template strand to form two hydrogen bonds with a T base on the new strand. This doesnt normally occur because: DNA polymerase cannot incorporate T into the newly synthesized strands. The T-T basepair contains two of the smaller sized bases. The normal A-T base pairing uses 3 hydrogen bonds so it will be preferred. The two T-T hydrogen bonds will be weaker than the two hydrogen bonds between an A-T pair. Question 3 Select one answer. 10 points What process is responsible creating distinct sets of proteins in skin cell compared to brain cell? DNA Replication DNA Mutation Base Titration Gene Expression Question 4 Select one answer. 10 points Which part of the nucleotide stores the genetic information? Phosphate group Nitrogen base Deoxyribose Ribose Question 5 Select one answer. 10 points Which of the following statements is FALSE? Both DNA replication and PCR use DNA polymerase. Both DNA replication and PCR use primers. Both DNA replication and PCR use a DNA template. Both DNA replication and PCR use helicase. Question 6 Select one answer. 10 points If radioactive nucleotide bases were provided to bacteria during DNA synthesis then after cell division you would find: Both bacteria would be equally radioactive. Neither would be radioactive because DNA polymerase can distinguish between isotopes. One bacteria would be radioactive and the other not. Question 7 Select all that apply. 10 points In which of the following organisms is it necessary to transport the mRNA across a membrane prior to protein synthesis. Select all that apply. Animals Plants Bacteria Viruses Question 8 Select one answer. 10 points What is the end result of DNA replication? Two DNA molecules one with two old strands and one with two new strands. Two DNA molecules which each have two new strands and two old strands. Two DNA molecules which each have one old strand and one new strand. Two DNA molecules each both have two new strands. Question 9 Select one answer. 10 points Does the DNA in the skin cell have the same sequence of bases as the DNA in the brain cell of the same organism? Yes the sequence of ALL DNA is the same. No some cells will have moms DNA other cells will have dads DNA. No the DNA sequence will vary based on cell type. Yes the sequence of bases should be the same in all cells of an organism. Question 10 Select one answer. 10 points Skin cells perform very different functions compared to brain cells. On the molecular level what makes skin cells different from brain cells in the same organism? Proteins DNA ATP pH Show less
