Document Summary
Genetics: study of inherited traits and their variation: heredity: transmission of traits and biological information between generations and how traits are transmitted, genes: units of heredity that tell cells how to make proteins that contributes to us. Genome: complete dna sequences - all of our cells have 2 copies of the genome: bioethics helps deal with issues of genetic technology and science in privacy, etc. Types of bases of dna: a adenine, t thymine, c cytosine, g guanine. To make protein, mrna is made by transcription of part of the dna: use translation to make the proteins, exome: 1-2% of the genome that encodes proteins. Mutation: changes in dna sequence: can cause disease or just different expressions of alleles. Chromosomes: highly wound continuous molecule of dna and proteins associated with it: body/somatic cells have 23 pairs of chromosomes (46 total) 22 pairs are autosomal (doesn"t differ between the sexes) Xy = male: karyotype: chart of chromosomes smallest to biggest.
