3.Genes and dorsal cell fate

Question 1

Egg Polarity Genes

Answer 1

Genes that establish the dorsal-ventral and anterior-posterior axes during egg development, such as gurken and torpedo.

Question 2

Gurken Gene

Answer 2

A Drosophila gene encoding the GRK protein, which signals via the TORPEDO receptor to establish dorsal follicle cell identity.

Question 3

Torpedo Gene

Answer 3

Encodes the Epidermal Growth Factor Receptor (EGFR) in Drosophila, important for specifying cell fate via signal transduction

Question 4

Complementation Test

Answer 4

A genetic method to determine if two mutations affect the same gene or different genes based on their ability to restore a wild-type phenotype.

Question 5

Chimera

Answer 5

An organism composed of cells derived from different zygotes, used experimentally to study gene function.

Question 6

i got this

Signal Transduction Cascade

Answer 6

A series of molecular interactions initiated by ligand-receptor binding, resulting in cellular responses.

e.g between glatze protein- toll receptor

Question 7

Oncogene

Answer 7

A mutated proto-oncogene that promotes uncontrolled cell division and tumor formation.

Question 8

Tumor Suppressor Genes

Answer 8

Genes that inhibit cell division; loss of their function can lead to cancer.

Question 9

Proto-Oncogene

Answer 9

A normal gene that facilitates cell proliferation but can become an oncogene through mutation.

Question 10

FLT3 Gene

Answer 10

A proto-oncogene whose mutations are implicated in acute myelogenous leukemia, leading to unregulated cell division.
