How do nucleotides form a double helix?

Answer 1

Nucleotides don't form a double helix. Single strands of DNA form a double helix, and single strands of DNA are made by nucleotides.

DNA is a single strand of nucleotides linked together; nucleotides are monomers that make up the polymer known as DNA. If you have a complementary strand of DNA (a strand that can basepair to the first strand, such as G:C or A:T), these two strands can form a double helix.

Adenine (A) with thymine (T) and guanine (G) with cytosine (C) are the complementary base pairs that form the double helix of nucleotides in DNA. The bases are joined by hydrogen bonds, which create a stable structure, and the sugar-phosphate backbones run antiparallel.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
