1) Imaginal disc is a group of epithelial cells present in the holometabulous larva of the insect which gets transformed into outside parts of the insect body like legs , wings etc during pupal transformation (metamorphosis).
During pupal stage, many larval structures are destroyed to form the adult structure through a rapid development. Each imaginal disc everts and gets elongated with the central part resembling whichever appendage is to be formed , it may be wings or legs etc. During larval period , these discs are undifferentiated which gets transformed at the pupal stage .
ASSIGNMENT 1: DROSOPHILA IMAGINAL DISC DEVELOPMENT 1) In Drosophila, the legs, wings and other adult structures...
2) Describe the antero-posterior patterning of the dorsal wing imaginal disc, including the major genes involved and their role in this patterning. 3) Describe the antero-posterior, dorso-ventral and proximo-distal patterning of the ventral leg imaginal disc, including the major genes involved and their role in patterning.
During Drosophila development, adult structures are formed from clusters of cells called imaginal discs, which are recognizable during larval and pupal stages. You are interested in the genes expressed in imaginal discs, and you have identified two such genes that are closely linked together. • Gene 1 is expressed in the imaginal discs that will become the adult antennae. • Gene 2 is expressed in the discs that will become the adult wings and legs. A map of the two...
1. According to the paper, what does lactate dehydrogenase (LDH) do and what does it allow to happen within the myofiber? (5 points) 2. According to the paper, what is the major disadvantage of relying on glycolysis during high-intensity exercise? (5 points) 3. Using Figure 1 in the paper, briefly describe the different sources of ATP production at 50% versus 90% AND explain whether you believe this depiction of ATP production applies to a Type IIX myofiber in a human....
