A is linked to T and C is linked to G via covalent bonds. In a nucleotide chain the nucleoties are linked via hydrogen bonds. NOw top scpre asks how nucleotide bases are linked. How do you know which way they are talking about to each other or to their complement on the other strand?
Thinking about it now i think if they wanted the covalent-meaning to other strand they would ask how are DNA strands linked, but im not sure. does anyone have any insight to a better wording of this question?

actually A is linked to T via Hydrogen bonds (2 to be exact)
and C is linked to G via Hydrogen bonds (3 to be exact)

on a single stranded DNA A will never be linked to the T directly, instead it will go through a phsophate and a sugar, then be linked. These are where there are phosphodiester bonds.

a nucleotide is a base, phosphate and sugar
a nucleoside is a base and sugar only (i think)

I suggest getting your definitions right, and then asking a more specific question. Or give us an example of a quesiton you think is vague

WOW I cant beleive i asked that my bad i knew that - but thanks for helping me pull it from the back of my head!

yup - a nucleoside is a base and sugar
