What is the phosphodiester bond and how is it drawn?

Answer 1

See Below

Nucleotide Monophosphates, NMPs, are nucleosides that have 1 phosphate group. Here is GMP.

All simple nucleotides have this phosphoester bond.

When one nucleotide makes a linkage with another nucleotide, the phosphate group (which already has 1 ester bond) makes a 2nd ester bond. This becomes a phosphodiester bond.

In the picture below, the phosphate group has one ester bond to the nucleotide below, and one ester bond to the nucleotide above. This is the phosphodiester bond.

Phosphodiester bonds, which connect the 3' carbon of one nucleotide to the 5' carbon of the next nucleotide through a phosphate group, are covalent bonds that form the backbone of nucleic acids, including DNA and RNA. Phosphodiester bonds are drawn as a line between the phosphate group and the adjacent sugar molecules, representing the linkage between nucleotides in a nucleic acid chain.

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.
