what is the linkage involved in nucleic acids

phosphodiester bonds

this is the structure/distribution of a phosphodiester bond

C - O - P - O - C

where does the first Carbon come from ?

where does the last carbon come from?

1. from the first nucleotide

2. from the second nucleotide

what is the structure formed when you combine 2 nucleotides

Dinucleotide

define polynucleotides

molecules formed by the repetition of nucleotides which are held together by a phosphodiester bond

function of nucleotide’s
