Document Summary
Humans 100,000+ genes, 1 gene on average 3,000 bases long. Protein synthesis: general definitions of transcription (dna- mrna) and translation. Transcription: rna polymerase, pre-mrna- immature rna (includes exons and introns, alternative splicing. _____ fuse into clusters unload ___ into ____ ____ Genes can be turned on and off by ____ ex of each (casein synthesis and secretion) Indirect genetic control bc produced by ____ reactions, enzymes proteins encoded by genes. Cell must duplicate before dividing so : dna storage chromatids and histones- up until midpoint (metaphase) of cell divison. Dna replication: unwinding, unzipping, building new dna strands, repackaging, histones, dna helicase, dna polymerase. Kill, no issues, cancerous, genetic defects in future generations. Cell cycle- produce 2 identical daughter cells- interphase and mitotic phase. Heredity, karyotype (how many chromosomes, how organized), homologous chromosomes, how many each parent, autosomes vs sex chromosomes x x vs xy. 2n vs n locus, alleles, polygenetic inheritance (multiple genes), pleiotropy (multiple phenotypes), sex-linked.
