ANSWERWhat does heterocyclic mean?
UMP - VERIFIED ANSWERA major component of RNA, but not DNA is
The structure of DNA consists of two chains, or strands, that are not identical, but are complementary.
This means that one chain binds to the other through hydrogen binding between the bases adenine and
thymine, and also between cytosine and guanine. Adenine will only bind to thymine, and cytosine will
only bind to guanine. Therefore, the two DNA strands are complementary because the bases of each
chain participate in complementary base pairing. - VERIFIED ANSWERScientists say that 2 DNA strands
are complementary. Briefly describe what is meant by complementary. Provide an example in your
response.
Non-covalent interactions contribute to the 3D shape and structures of RNA molecules by allowing RNA
to fold on itself via hydrogen bonding between complementary base pairs. Nucleotides interact with
complementary resides to produce a secondary structure. - VERIFIED ANSWERBriefly describe how non-
covalent interactions contribute to the 3D shapes and structures of RNA molecules.
