Unit 7 DNA - Protein
CA 7 DNA to Protein
| Term | Definition |
|---|---|
| -ase | forms names of enzymes |
| Anticodon | a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule |
| base pairing | principle that bonds in DNA can form only between adenine and thymine and between guanine and cytosine |
| Codon | a sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule. |
| DNA polymerase | Enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule |
| DNA | A complex molecule containing the genetic information that makes up the chromosomes. |
| double helix | two strands of nucleotides wound about each other; structure of DNA |
| genetic code | collection of codons of mRNA |
| Messenger RNA (mRNA) | RNA molecule that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell |
| pheno- | to show |
| Replication | process of copying DNA prior to cell division |
| Ribosomal RNA (rRNA) | type of RNA that combines with proteins to form ribosomes |
| RNA polymerase | enzyme that links together the growing chain of RNA nucleotides during transcription using a DNA strand as a template |
| RNA | A single-stranded nucleic acid that passes along genetic messages |
| script | to write |
| Telomere | repeating nucleotide at the ends of DNA molecules that do not form genes and help prevent the loss of genes |
| trans | across |
| Transcription | (genetics) the organic process whereby the DNA sequence in a gene is copied into mRNA |
| Transfer RNA (tRNA) | type of RNA molecule that transfers amino acids to ribosomes during protein synthesis |
| Translation | the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm |
