| What are nucleotides made of? | + a common sugar (deoxyribose) + a phosphate group + a base |
| What are the different bases? | + adenine (A) + thymine (T) + guanine (G) + cytosine (C) |
| How do the bases pair? (base pairing) | + A always pairs w/ T + C always pairs w/ G |
| How is DNA copied? | 1. Weak bonds between bases are unzipped & separated into 2 strands 2. Free nucleotides pair w/ exposed bases, forming new strands 3. Because A always pairs w/ T, the 2 new stands are identical. |
| how does genetic code affect the making of proteins? | They determine which amino acids are used to make a protein, & their order. This affects how the polymer folds. |
| What is a triplet code? | The 3 bases on a DNA strand that code for one amino acid. |
| Where re amino acids joined together to make proteins? | @ the ribosomes in the cytoplasm. |
| What is messenger RNA (mRNA) | a single strand of DNA that carries information from the nucleus to the ribosome. |
| What are the differences between DNA and mRNA? | + mRNA is only 1 strand + in mRNA thymine (T) is replaced by uracil (U) |
