1   INET Lab Report 8 DNA Structure and Function Report Template Student:    Email :   Date:    I. DNA Structure EXERCISE 8.1  – Construct the DNA molecule 5.   Which carbon atom (position) in the sugar forms a covalent bond with the nitrogen base? The outside rails Which carbon atoms of deoxyribose bond with the phosphate molecule? The outside ones 6. Which bases will pair with one another? Adenine will pair only with Thymine guanine will pair only with cytocine 9. In  Figure 8.7 , write the letters that stand for the complementary bases in your double-stranded DNA puzzle.  Indicate  the number of hydrogen bonds between the complementary base pairs by dotted lines (- for a single bond, = for a  double bond). c =g - a -t = c =g - ©  Access Learning Systems

2   a -t = Figure 8.7 Complementary DNA nucleotide strands The phosphate group at the top on the left strand is attached to which carbon atom (position) in the sugar?  Which  carbon atom of ribose would be attached to the next phosphate group added to the bottom of the left strand? C,A Which carbon atom of ribose would be attached to the next phosphate group added to the top of the right strand?  Which carbon atom of ribose is attached to the bottom right phosphate group? G,T What do you notice about the direction in which each strand is oriented? It is oppositve of the other side.  II. DNA Replication EXERCISE 8.2  – DNA replication 3. How much of the newly formed DNA molecule is new and how much is the original strand?  What term is used for this  type of replication?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
