Effects of x-irradiation on DNA synthesis in salivary gland cells of Drosophila hydei

Creator:

Wong, Patrick Tin-Choi, 1942-

Abstract:

The effect of X-irradiation on DNA synthesis in larval salivary glands of Drosophila hydei was studied using the technique of liquid scintillation spectrometry and autoradiography. DNA synthesis in salivary glands of synchronized larvae was measured at successive stages of third instar development by in vitro uptake of ³H-thymidine for a...

gland cells of Drosophila hydei AN ABSTRACT OF THE THESIS OF PATRICK TIN-CHOI WONG for the (Name) in
Temperature-effective periods during crossvein development in crossveinless-like strains of Drosophila melanogaster

Creator:

Wong, Patrick Tin-Choi

Abstract:

This investigation is concerned with the determination of the temperature-effective period (T.E.P.) for crossvein development at physiological temperatures using three isogenic crossveinlesslike (cvl) lines of Drosophila melanogaster. The method used to determine T.E.P. relies on temperature differences in phenotypes and on a program of transfers from one temperature to another...
