1. What is the difference between a parasegment and segment in Drosophila development? a) Segments correspond to the anatomical divisions seen in larvae and adults, whereas parasegments are subdivisions of the embryo that correspond to regions or domains of gene expression. b) Parasegments correspond to the anatomical divisions seen in larvae and adults, whereas segments are subdivisions of the embryo that correspond to regions or domains of gene expression. 2. Which of the following statements about vertebrate Hox genes is...

Maternal effect genes are a special class of genes that have their effect in the reproductive...
Maternal effect genes are a special class of genes that have their effect in the reproductive organs of the mutant. They are interesting because the mutant organism may appear phenotypically normal, and it is the progeny that express detectable differences, and they do so whether the progeny have inherited the mutant gene or not. The first maternal effect gene identified was the gene controlling shell coiling in the water snail Lymnaea peregra. Alleles of this maternal effect gene are non-lethal...

Developmental Biology Help! Please answer all the questions 1) We discussed the fact that each stripe expression pattern is affected by the enhancer region that is utilized. Knowing that the maternal genes and the gap genes can both contribute to the pair-rule genes, and that in many cases multiple stripes may be contained in one area of GAP, how does the embryo have definition of stripes if all of these transcription factors can be within the same cell A it...

See the diagram below regarding the process of V-J recombination. After RAG1,2 activity and hairpin formation, an endonuclease cuts at the positions marked by the arrows. CATGCG is then added to the D gene segment and ACAGG is added to the gene segment. In the absence of any further modification, the two gene segments are filled in and then ligated together. Answer the following in the essay box provided. First - provide the full name of the enzyme that adds...
