| Term | Definition |
|---|
| nucleotides | building blocks of nucleic acids |
| a phosphate, a sugar, and a base | What are the bulding blocks of nucleotides? |
| ribose and deoxyribose | What are the two possible sugars in nucleotides? |
| possible bases found in nucleotides | A (adenine) G (guanine) T (thymine) C (cytosine) U (uracil) |
| thymine | What base is NOT found in RNA? |
| uracil | What base in NOT found in DNA? |
| deoxyribose | What sugar is in every DNA nucleotide? |
| ribose | the sugar in ATP |
| three phosphate groups | How is ATP different than nucleotides found in RNA and DNA? |
| RNA is different from DNA | RNA: a single helix; U instead of T; ribose instead of deoxyribose |
| ATP | It is the only source of energy that living things can use directly. |
| DNA | It makes RNA- and controls heredity by directing protein synthesis |
| RNA | it makes proteins |
| DNA | makes up the chromosomes, and is found in the nucleus of a cell |
| ATP | made in the cytoplasm of a cell, most is made by mitochondria |
| the bases | DNA is often compared to a ladder, what molecules make up the rungs? |
| phosphates and sugars | What molecules make up the sides of the "ladder"? |
| T | What DNA base is complimentary to A? |
| G | What DNA base is complimentary to C? |
| A | What DNA base is complimentary to T? |
| C | What DNA base is complimentary to G? |
| U | What RNA base is complimentary to A? |
| A | What RNA base is complimentary to U? |
| A and G | Which bases are purines? |
| purines | Which bases are larger, purines or pyrimidines? |
| C,T, U | Which bases are pyrimidines? |
