watson -Crick pairing 5. Now draw tautomers of the nucleotides and show alternative base paring that could result form tautomeric shifts:
Question 1 1 pts Why is it important for DNA to have complementary base pairing? O Complementary base pairing allows base pairs to be packed in the most energetically favorable arrangement inside of the double helix structure. O Complementary base pairing will pair a purine with a purine, which are a similar width, thus they are able to hold the sugar-phosphate backbone an equal distance apart along the DNA molecule o Complementary base pairing is only important for maintaining the...
Question 4 (2 points): In the space below, draw the two Watson-Crick base pairs that are present in DNA? Draw only the nucleobases. Indicate atoms where the nucleobases are attached to sugar. Also, make sure to draw all H-bonds connecting two nucleobases in the base pairs.

Question 8 1 pts Base pairing is an essential property of a DNA helix. Its presence or absence is very important for all of the following EXCEPT: Establishing the 5' to 3' polarity of a piece of DNA Providing a primer for DNA polymerase. Identifying an origin of replication. Identification of a damaged nucleotide that needs to be repaired. The use of a template to make a new daughter strand Question 9 Primase is an essential component of the replication...
a) Please draw the nucleotide sequence AC, from DNA; start at 5' and draw the backbone vertically down the page. Please draw a 5' phosphate and 3' hydroxyl. b) Please draw just the bases of the complementary strand, including a "squggle bond" to indicate the attachment to the ribose; mark hydrogen bonds with the standard dashed lines. c) Please label the bases of both strands with their names. d) Please explain why you would lose points in part c if...
C6) (8 points) a) Draw a GC base pair, such as one would see in a standard B form DNA double helix. Include the full structure of each nucleotide in the base pair and use dashed lines to indicate the specific hydrogen bonding interactions between the bases. b) Briefly explain why you would expect to see a higher portion of guanine and cytosine bases (compared to thymine and adenine) in the DNA sequences of thermophilic bacteria (i.e. bacteria that live...
