Document Summary
Modification of a gene or chromosome during egg/sperm formation or early stages of embryo growth but is fixed during the persons lifetime. Permanently affect the phenotype of the person, but are not permanent over generations and does not change the dna sequence. If females had to x chromosomes activated too much gene product will get created and the cell will die. One x chromosome in females are not active (cid:1) Barr bodies (inactive x) are found in female cat cells only. Offspring distinguished between maternal and paternal inherited (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) organisms (cid:1) organisms (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) chromosomes. Offspring express either maternal or paternal allele not both. Dna cloning isolating & amplifying specific dna sequences. Genomics & proteomics: analysis of genomes & proteomes of. Biotechnology: add new genes; transgenic or genetically modified. Recombinant dna dna from 2 or more sources. Vector delivers foreign dna into host cell.
