Drosophila axes & pattern formation| CSIR-NET (LS)| Unit-5| Developmental Biology| Dr. Tamali Sinha
The axes of the fruit fly Drosophila melanogaster are established during oogenesis. The anterior-posterior axis is established by maternal mRNA gradients that are deposited in the egg during oogenesis. The mRNAs Bicoid, hunchback, nanos, and caudal are critical to the formation of the anterior-posterior axis. The dorsoventral axis is established by a signal that regulates the entry of Dorsal into the nucleus essential for ventralization of cells.
The video talks about the details of processes involved in axes formation in Drosophila.
Tamali's Classes has been created for children, students and people who want to learn Biology and Science and understand the subject efficiently. My intention has been to deliver my knowledge to every interested person and spread my knowledge to everyone without any hassles. I believe education is for all and must be reached to all effortlessly.
