(Problem 27, part a) For entertainment on a Friday night, a
genetics professor proposed that his children diagram a
polynucleotide strand of DNA. Having learned about DNA in
preschool, his 5-year-old daughter was able to draw a
polynucleotide strand, but she made several mistakes. The
daughter’s diagram (represented here) contained at least 10
mistakes. Which option, below, is NOT a mistake made in this
diagram?

Please explain how you solved this problem clearly.Thanks in
advance.
A. Neither 5′-carbon atom of the two sugars is directly linked
to phosphorous. |
|
B. Neither 5′-carbon atom of the two sugars has an OH group
attached. |
|
C. Neither sugar molecule has oxygen in its ring structure
between the 1′ and 4′-carbon atoms. |
|
D. In both sugars, the 2′-carbon atom has an –OH group
attached, which the 2′-carbon atom of deoxyribonucleotides does not
have. |
|
E. An –OH group is attached at a hydrogen atom rather than the
1’carbon of both sugars. |
|
F. A hydrogen atom is attached at the 3’position in both
sugars, rather than an –OH group. |
|
G. An –OH group is attached at the 1’carbon of both sugars
rather than a hydrogen atom. |
