Chapter 8 Totora
| Question | Answer |
|---|---|
| Gene | a segment of DNA that encodes a functional product, usually protein |
| Chromosome | structure containing DNA that carries hereditary information |
| Genome | all the genetic information in a cell |
| Genetics | the study of what genes are, how they carry information, how genes are replicated |
| Genomics | the molecular structure of genomes |
| Genotype | the genes of an organism |
| Phenotype | the expression of the genes |
| DNA | polymer of nucleotides: adenine, thymine, cytosine, guanine |
| DNA synthesis are made | DNA copies are made by DNA polymerase |
| DNA is transcribed to make | RNA (mRNA, tRNA, rRNA) |
| Frameshift mutation | Insertion or deletion of one or more nucleotide pairs |
| Horizontal gene transfer | the transfer of genes between cells of the same generation |
| Genetic Recombination | exchange of genes between two DNA molecules |
| Vertical gene transfer | occurs during reproduction between generations of cells daughter cells |
