Embryology 2023 Exam 2 Objectives: Lectures 9 (part)-16 | with complete solution Nodal is a signaling molecule produced by the primitive node. What is its role in the induction of the primitive streak and the establishment of left-right symmetry? It induces primitive streak and helps to establish left-right symmetry. It is a symmetry breaking molecule in the left side of the embryo. What is the first sign of asymmetry in early development? What roles are played by Nodal and Left-1? Involve...

Lecture notes from BIOL3015 Regulation of gene expression, transcriptional regulation. Covering: regulatory circuits, negative feedback, toggle switch circuits, somitogenesis oscillator, circadian clocks, transcriptional circuits of fruit flies, transcriptional circuits of mammalian clocks, transcriptional circuits of budding yeast cell cycle, northern blot, qRT-PCR, 'Sanger' sequencing, 'Next generation' sequencing and transcriptional phenotyping.

These are comprehensive, organised, and easy-to-read notes that cover a two-unit module consisting of eighteen lectures on developmental biology, the developing embryo, and ethics & philosophy of science. These are perfect for bioscience and animal/veterinary students as well as prospective students who need a quick recap of high school biology. I am a third-year MSc Bioveterinary Sciences student at the Royal Veterinary College, London. I have achieved a 1st ( 70%) in both my years and my fri...

Hi there! Using these cases I received a 8,3 for the exam. However, I would still recommend the lectures as repetition. Good luck with the course and with your exam!
