Nucleic Acids & Protein synthesis
| Term | Definition |
|---|---|
| DNA nucleotide has three parts. | sugar, phosphate and bases. |
| Adenine and Guanine have two rings of carbon. | Cytosine and thymine |
| Replication- | The process of copying DNA in a cell. |
| RNA | repeating units: consists of ribose (sugar) Uracil. RNA single stranded. |
| Transcription: | Process by which genetic information is copied from DNA to RNA. |
| protein synthesis | The production of proteins. |
| The Genetic Code | correlation between a nucleotide sequence and an amino acid sequence. |
| 3 mRNA | codon |
| Start codon | AUG |
| stop codon | UAA, UAG, UGA |
| Translation | process of assembling polypeptides from information encoded in RNA |
| Purine | double ringed carbon and nitrogen atoms. |
| Pyrimidines | Single ringed base of carbon and nitrogen atoms |
| complementary base pairs | contains double ringed purine |
| base sequence | order of nitrogen bases on a chain of DNA |
| helicases | separate DNA strands |
| replication fork | when two strands separate. |
| DNA replication | process by which DNA is copied in a cell before a cell divides by mitosis, meosis or binary fission. |
| promoter | is a specific nucleotide sequence of DNA where RNA polymerase binds to the promoter. |
| termination signal | is basically the"stop sign" |
| genome | entire gene sequence of the human. complete genetic content. |
| ribose | sugar |
| anti codon | three nucleotides on the RNA that are complementary to the sequence of a codon |
| protein structure | every protein is made of one or more polypeptides |
| translation | all three major types of RNA are involved in translation: the making of protein. |
| messenger RNA | a single stranded RNA molecule that carries the instructions from a gene to make a protein. |
| transfer RNA | transfers amino acids to the ribosome to make a protein. |
| one special codon | AUG acts as a start codon |
| deoxyribose | five carbon sugar in a DNA nucleotide |
