FAC1601 Assignment 2 September 2024
What feature of mononucleotides provides the energy needed for polymerization
when nucleic acids are formed? - answer-their phosphate groups
Rank the following base pairs according to their stability.
Rank from most to least stable. To rank items as equivalent, overlap them. -
answer-most stable: 3 H connecting, 2 H connecting, 1 H connecting
By convention, the sequence of bases in a nucleic acid is always written in which
direction? - answer-5' → 3'
What forms the "backbone" of a nucleic acid? - answer-a chain of sugar and
phosphate groups, linked through phosphodiester bonds
Hairpins and stem-and-loop patterns make up what part of RNA's structure? -
answer-secondary
Starting at the 5' end, what is the base sequence of the RNA strand shown in the
figure? - answer-UAGC
