2.Genes and head formation

Question 1

Model Organism

Answer 1

A species used in research to understand basic biological processes, typically due to shared genetics or conserved traits with humans. like drosophila

Question 1

Morphogen

Answer 1

A molecule that forms a concentration gradient and influences cell fate based on its spatial distribution

Question 2

Maternal-Effect Genes

Answer 2

Genes found in mothers whose products are required for proper development of the embryo

Question 3

Bicoid Gene

Answer 3

A maternal-effect gene in Drosophila critical for anterior (head) formation by producing BICOID protein, a morphogen.

Question 4

Hunchback Gene

Answer 4

A gap gene regulated by BICOID protein that encodes a transcription factor for segmentation.

Question 5

got asked

Zinc Finger Protein

Answer 5

A DNA-binding protein with a structural motif that interacts with specific DNA sequences to regulate transcription.

Question 6

Genetic Dissection

Answer 6

A method to identify genes by

1.inducing mutations,
2.observing phenotypes, and
3.correlating them with gene function.

Question 7

In Situ Hybridization

Answer 7

A technique to detect nucleic acids in cells/tissues using complementary probes for visualization.

Question 8

Homeotic Genes

Answer 8

Genes that regulate the development of anatomical structures, such as bithorax and antennapedia in Drosophila.

Question 9

Segment Polarity Genes

Answer 9

Genes like hedgehog that establish cell fates in embryonic segments.
