The two DNA strands are known as polynucleotides as they are composed of simpler monomeric units called nucleotides.
Web8 jun. 2024 · The two strands of the helix run in opposite directions. This antiparallel orientation is important to DNA replication and in many nucleic acid interactions. Figure … WebAnswer: RNA can be single-stranded or form a double-stranded RNA double helix. RNA also forms lots of interesting structures with loops and such that make compact shapes …
Tertiary structure refers to the locations of the atoms in three-dimensional space, taking into consideration geometrical and steric constraints. It is a higher order than the secondary structure, in which large-scale folding in a linear polymer occurs and the entire chain is folded into a specific 3-dimensional shape. There are 4 areas in which the structural forms of DNA can differ. Web[Just emphasizing that a single strand nucleic acid, even without secondary structure, also forms helices.] The helices of both DNA and RNA form in aqueous solution because of …
