Document Summary
The chromosomes condense, and the nuclear envelope breaks down. crossing- over occurs. Pairs of homologous chromosomes move to the equator of the cell. Homologous chromosomes move to the opposite poles of the cell. Chromosomes gather at the poles of the cells. the cytoplasm divides. Dna unwinds itself and then breaks in half to form the other side of the helix the replicate itself. Protein synthesis transcription then translation, stringing amino acids together. Genes portions of dna which are code for particular traits, one kind of phenotype. Chromosomes a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. Alleles one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. Chromatids each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Alleles or variation of the gene, the code.
