DNA and protein synt
| Question | Answer |
|---|---|
| transcription | the process where the DNA sequence in a gene is copied into mRNA |
| translation | the process where genetic information coded in mRNA directs the formation of a specific protein at a ribosome |
| mRNA | type of RNA that carries instructions from DNA in the nucleus to the ribosome |
| tRNA | type of RNA that carries amino acids to the ribosome |
| codon | sequence of three bases on a strand of mRNA that provides genetic code information for a particular amino acid |
| anticodon | group of three bases on a tRNA molecule that are complementary to an mRNA codon |
| complementary base pairing | In DNA, T pairs with A; G pairs with C; RNA, U pairs with A and G pairs with C |
| cytoplasm | A jellylike fluid inside the cell in which the organelles are suspended |
| ribosome | organelles at which proteins are synthesized. |
| nucleus | Membrane bound organelle in eukaryotes containing DNA |
| amino acid | building block/monomer of proteins |
| adenine | pairs with uracil in RNA |
| cytosine | pairs with guanine |
| nitrogenous bases | adenine, guanine, cytosine, thymine, uracail |
| deoxyribose | sugar in DNA |
| ribose | sugar in RNA |
| nucleotide | consists of a phosphate group, sugar, and nitrogen base |
| ribosome | organelle where amino acids are bonded together to form proteins |
| codon | three-base sequence on messenger RNA that codes for a single amino acid |
| DNA | A double-stranded, helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell's proteins |
| the nitrogen containing base that is found only in RNA is | uracil |
| what anticodon would line up with the codon UAC | AUG |
| in DNA, what base pairs with cytosine | guanine |
| what type of RNA has anticodons? | tRNA |
| what do stop codons code for | the end of an amino acid chain |
| UAC codes for | Tyrosine |
| AGG codes for | Arginine |
| nucleotide | monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base |
| DNA vs RNA | deoxyribose sugar vs. ribose sugar, thymine vs. uracil , double strand vs. single strand |
| rna structure | single stranded |
