why are the third instar larval salivary glands of drosophila the organs of choice for making chromosome squashes?
Homework Answers
Scientist have always found a huge cytological advantages provided by the giant salivary glands of drosophila .The giant polytene chromosomes from Drosophila third instar larval salivary glands provide an important model system for studying. Because we can observe chromosomes undergo many rounds of replication in the tissue. In the absence of cell division, it produce nearly 1000 copies, which gives result of a enlarge chromosome along with a DNA Thus creating an opportunity to correlate chromatin morphology with the localization of specific proteins.

Map d Gunter Korge examined several proteins that are secreted from the salivary glands of Drosophila melanogaster during larval development. One protein, called protein fraction four, was encoded by a gene found by deletion mapping to be located on the X chromosome at position 3C. (G. Korge. 1975 Proceedings of the National Academy of Sciences of the United States of America 72:45504554) Korge observed that, about five hours before the first synthesis of protein fraction four, an expanded...
