Document Summary
Biology 1202b: lecture 10 dna structure, organization, and replication i. Proteins may perform a variety of other functions in the cell as well. Where do proteins come from: dna replication transcription to mrna translated to protein. How does the neanderthal genome compare to modern humans: single nucleotide polymorphisms, catalogued sites where all present day humans have same snp but differ from. Differ at 31, 389 snps 87 proteins. Early 1900s scientists thought protein was the molecule of heredity: 20 amino acids vs 4 nucleotides. Protein contains more information per unit: they took a lot of convincing that dna was responsible. Despite results of avery and griffith, not all were convinced: protein made more sense. More information can be held hershey and chase remove all doubt. Results prove dna is the genetic material. Started race to find structure of dna. Nucleotide composition: 5-carbon sugar deoxyribose, phosphate group, 1 of 4 nitrogenous bases.
