SLS Bio12 DNA HH
SLS Bio12 DNA Protein Synthesis HH
| Term | Definition |
|---|---|
| complementary base pairing | the specific arrangement of bases in nucleotides (adenine with thymine, cytosine with guanine) |
| DNA Helicase | an enzyme that unwinds the double helix of DNA |
| DNA Polymerase | an enzyme that assembles the nucleotides on the DNA strands |
| recombinant DNA | the combination of two or more different sources of DNA put together artificially |
| replication | duplicating the strands of DNA |
| semi conservative replication | creating two new strands of DNA which both have a strand from the original DNA |
| anti codon | a sequence of three bases located on tRNA which complement three other bases on mRNA |
| codon | a sequence of three bases located on mRNA that correspond to a specific amino acid attached to tRNA |
| DNA sequence (genetic code) | the specific order of bases in DNA |
| elongation | a step in translation where the tRNA brings in amino acids and forms a polypeptide chain |
| environmental mutagen | induces a mutation (radiation, virus, chemicals etc) |
| genetic disorder | a disorder that has been inherited through your genes (Huntington disease, Marfan syndrome) |
| initiation | the starting codon on the mRNA that begins the process of translation |
| messenger RNA (mRNA) | carries the blueprint for the structure of the protein that will be made, made from copying DNA |
| mutation | changing the structure of the gene sequence in your DNA, caused by one single alteration |
| termination | the stop codon on the mRNA that tells the protein to end |
| transcription | the process of making RNA strands from copying the information from the DNA strands |
| transfer RNA (tRNA) | in the cytoplasm where they bring the correct amino acid to the ribosome for translation to occur |
| translation | the process where polypeptide chains are made with the aid of the ribosome, mRNA and tRNA |
