Lesson 910 of 1524
Biochemistry of the Genome
DNA was discovered and characterized long before its role in heredity was understood.
Practice this chapterDNA was discovered and characterized long before its role in heredity was understood. Microbiologists played significant roles in demonstrating that DNA is the hereditary information found within cells
In the 1850s and 1860s, Gregor Mendel experimented with true-breeding garden peas to demonstrate the heritability of specific observable traits In 1869, Friedrich Miescher isolated and purified a compound rich in phosphorus from the nuclei of white blood cells; he named the compound nuclein.
Be able to describe the discovery of nucleic acid and nucleotides; explain the historical experiments that led to the characterization of DNA; describe how microbiology and microorganisms have been used to discover the biochemistry of genes.
