Meselson - Study guides, Class notes & Summaries

Everything is just like the original experiment (the bacteria is grownin many generations in 15N and then switch to light 14N) and DNA replication is semi-conservative and the culture is grown in light media for two generations. - Answer-tube C In a cell grown for many generations in the presence of fluorescent nucleotide, and then moved to grow in a medium containing only normal, nonfluorescent nucleotides for exactly one round of DNA replication, which pattern of fluorescence shown in the...

People to Know - AP Biology Exam Questions and Answers Gregor Mendel Monk who grew up in Austria, experimented with garden peas in 1857 to study inheritance, documented "particulate mechanism", came up with laws of independent assortment and segregation. Thomas Hunt Morgan Came up with first solid evidence associating a specific gene with a specific chromosome by working with various varieties of Drosophila; invented notation for symbolizing alleles; discovered sex-linked trait of whit...
