Document Summary

Lecture 12 genetics and disease (oct 17) Dna is transcribed into rna and translated into proteins. Dna is our genotype, protein gives us our phenotype. Can be good genetic diversity leading to evolution. Insertion extra base pair put in (interrupts codon sequence) Substitution should have been t, now an a. Deletion deletion of part of chromosome (missing genetic info) Duplicate not necessarily good thing to have more dna. Translocate chromosome 2 is now located on chromosome 12. Somatic cells reproduce through mitosis (everything other than gametes) Will not be passed down b/c not located in gamete (non-inheritable) Each cell in nucleus as genetic info (dna) Used to think we had millions of genes, when in fact we have about 25000. Genes in dna arranged in 46 chromosomes that happen in pairs. 22 pairs of autosomal chromosome (non sex) Genes inherited in pairs one set form mom and one set from dad.
