Nucleic Acids
1) How many categories of naturally occurring nucleic acids are
there?
a. What’s the difference between them (like in a pentose)?
b. What are their purposes?
2) How many parts does a nucleotide consist of? What are they?
Nucleic acid = DNA or RNA
DNA OR RNA = 3 parts
3 parts = phosphate group, a sugar, + nitrogenous base
Pentose sugar = deoxyribose or ribose
Missing an O
Has an extra O
OH H
OH OH
3) What kind of reaction links nucleotides together?
4) Describe a segment of DNA or draw a picture. Explain the
relationship between the strands as well as what they consist
of.
As the sugar-phosphate backbone
5) Transcribe this DNA strand:
5’ ATGTCAATGGA
Now provide the mRNA:
0
