Document Summary
Understand why genetics is an important non-modifiable determinant of disease. Understand how genetic mutations can lead to disease. Understand how genetic information can inform prevention programming. Watson and crick -> co-discoverers of dna structure in 1953. 4 types of bases: a(adenine), g(guanine), t (thymine) c(cytosine) Dna (deoxyribonucleic acid) tells cell what its function is. Order of bases -> exact instructions required to create a particular organism with unique traits. Dna found in nucleus and mitochondrion, primarily in nucleus. Dna serves 2 purposes: replication, generation of form. Chromosome= millions of base pairs with some proteins. Genomics -> how complete set of dna affects disease all human cells have dna except red blood cells. >> want complete genome of all participants to be able to compare those who develop a disease vs. those who do not. Sequence of bases of gene contains instructions to make a protein. Tells cell when a gene should be used.
