What are the functional groups of DNA?

Answer 1

The functional groups are amine, amide, hydroxyl, glycoside linkage, and phosphodiester.

First, let's look at the bases in DNA.

Adenine, guanine, and cytosine have amine (#"-NH"_2)# groups, while thymine, cytosine, and guanine have amide (#"-CONH-"#) groups.

The bases are joined in DNA to form nucleotides with the general structure

) between the sugar and the base, and a hydroxyl group (#"-OH"#) and a phosphate ester (#"R-O-PO"_3^"2-"#) on the sugar.

Finally, we look at a DNA strand.

Answer from HIX Tutor

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.
