DNA & RNA INtroduction

DNA is a biological molecule made of smaller units called

• nucleosides

• nucleotides

• adenine, thymine, cytosine, guanine

• all of the above

The image on the left is showing the

• ribose sugar

• deoxyribose sugar

Adenine & Guanine are

• Purines

• Pyrimidines

The bond formed between the Nitrogenous base & the sugar

• phosphodiester

• glycosidic

• ester

this bond results in the backbone of the nucleic acids

• ester bond

• glycosidic

• phosphodiester

this nitrogenous base is only found in RNA

select all that apply. phosphodiester bonds are formed between __________________ and ____________________

• phosphate group on carbon 5 of sugar

• phosphate group on carbon 1 of sugar

• carbon 3 on another pentose sugar

• nitrogenous base

_______________ is the reaction that takes place to form the bonds in nucleic acids

The structure in the image is a
